After more than 10 months in development and 1400 commits, it feels so good to announce Remotion 3.0!

I am convinced that Remotion Lambda is the best piece of software that I have ever written. It is the final puzzle piece needed to complete our vision: A full stack for developing video apps! Enjoy the changelog, and if you haven't, check out the Remotion 3.0 Trailer.

Announcing Remotion Lambda

Remotion Lambda is a distributed video renderer based on AWS Lambda. It is made for self-hosting, so you deploy it to your AWS account. Once your Lambda function is up, you can give it rendering tasks, which it will split up into many small units of work that get processed in parallel by spawning itself many times.

Lambda is the best of all worlds:

  • Fast: Lambda can render a video up to many times faster than the fastest consumer computers. The longer the video, the higher the speed gain. The Remotion Lambda trailer was rendered in 15 seconds instead of 60 seconds, and a 2 hour video was rendered in just 12 minutes[1].

  • Cheap: You only pay for when you are rendering. The Lambda functions use ARM architecture for best price-performance efficiency.

  • Scalable: You can render many multiple videos at the same time. Lambda concurrency limits apply, but can be increased.

  • Easy: Chromium and FFMPEG are already pre-installed, and we handled all the edge cases. You only need to code your video, follow the steps to deploy a function and invoke a render.

All functionality is available via CLI commands and Node.JS functions. We've written 45 pages of documentation, released over 50 alpha versions to testers, and written many tests from unit to end-to-end. Lambda is mature and used in production by companies like Combo and Jupitrr.

Parallel rendering and encoding

Previously, rendering frames, and stitching them together to a video has been a sequential process where one step can start once the other has finished. In Remotion 3.0, stitching can start while rendering is still in progress! This will result on average in a 10-15% speedup.

Additionally, downloading audio assets now happens earlier in the rendering pipeline and if you rely on remote audio, you should see a handsome speedup as well.

New renderMedia() API

A new function has been added to @remotion/renderer called renderMedia(). It combines already existing functions renderFrames() and stitchFramesToVideo() but takes advantage of the new parallel rendering pipeline. It can render videos as well as audio and requires fewer arguments, so it's a win for speed and ease of use!

New openBrowser() API

Since opening and closing a browser instance can take time, we introduce a new API called openBrowser() for opening an instance of Puppeteer that you can use across the SSR APIs: renderMedia(), renderStill(), getCompositions(), and renderFrames().

Better error reporting

We are taking an initiative to make error easier to understand. While much of error handling has been handled by third-party libraries until now, we've inlined the logic, allowing us to streamline it. Minified errors are being symbolicated, we've implemented a new error overlay, and timeout errors are more descriptive. Let us know what you think!

A minified error that happened inside a Chrome browser inside a remote Lambda function displays a proper stacktrace!

Our custom error overlay has the ability to open the troublesome file in your default editor, and look for similar GitHub issues.

Config file can now import other files.

In the remotion.config.ts file, you can now import other files. Under the hood, we use ESBuild instead of Typescript to read the file. This was a paint point before: Node.JS APIs don't read from the config file and require you to specify the options explicitly. Configuration such as a Webpack config override could not be shared in a good way between CLI and Node.JS renders so far, which we address with this change.

React 18 supported

React 18 is now supported and we recommend that you upgrade to it. See our React 18 upgrade guide on how to do it!

Node 14, ESLint 8

Keeping our stack modern allows us to move faster and also, eliminate dependencies.

With Remotion 3.0, support for Node 12 is dropped, and we officially support Node 18. Our ESLint config has been updated to take advantage of ESLint 8, which is now also officially supported.

How to update

Read the migration guide to update to Remotion 3.0. The most severe breaking changes revolve around server-side rendering in an attempt to make it faster and simpler. Other than SSR changes and the Node 14 requirement, nothing should break.

The biggest announcement of this release is that the @remotion/player package is now generally available - but not just that, we have some other sweet new features too!

<Player/> is now stable

With the <Player/> component, you can embed a Remotion Video inside a React app without rendering the video. The API is modeled after the native HTML <video> tag that many developers are already familiar with.

The API allows you to use our predefined controls, or build your own. Familiar UI patterns like volume slider, fullscreen button, as well as gesture mechanics such as click to play/pause are supported.

You can dynamically update the props of the video at runtime, which creates an experience that stuns user: videos that react to their user input!

On mobile, restrictive policies prevent auto-play of audio content. We help you architect your player so it can play audio in as many cases as possible while still respecting the browser policies. This includes the option to mount silent audio tags, activate them while the user interacts with the page and use them later to play audio.

In this release, we added a new renderLoading prop and wrote docs for how to scale your player, code-sharing between Remotion and Create React App/Next.JS and preloading assets.

See the landing page for @remotion/player
Demo and Documentation

New error overlay

Recently, we broke the error overlay that pops up when your code contains an error. This is now fixed and we went deeper than ever before!

The Fast Refresh and error overlay is now inlined in our codebase and allows for customization that makes sense for Remotion. The overlay now matches the dark theme of the Remotion Preview and includes handy links such as opening a file in the editor, looking for the error in our GitHub issues and our Discord community.

Support for /public folder

You can now put static files inside a /public folder in your Remotion project and load it using the new staticFile() API. If you include the new <Player /> component in a Create React App or Next.JS project, the folder can be shared across Remotion and the framework you are using.

<Audio /> or <Video /> now support data: URLs

Data URLs are now valid sources for <Audio /> and <Video /> tags. This is useful for example for tones that are programmatically generated. To help with development of such projects, a new API was added to the @remotion/media-utils project: audioBufferToDataUrl(). See our festive Tone.js sample project for an example!

New audiogram template

When running npm init video, there's a new template to choose from: "Audiogram"! This one allows you to convert podcast clips to clean visualizations that you can post on social media.

getCompositions() now returns defaultProps

The getCompositions() API has been updated to return a new field for each composition: The defaultProps that you have specified for that composition.


  • Fixed videos playing in the <Player /> after they should have ended.
  • Fixed ended event in the <Player /> not firing correctly.
  • Fixed certain vulnerability messages that would show up during installation.
  • Updated @remotion/three to use React Three Fiber v7.

What's next

The next release is finally going to be our new major new release containing a refactor of our rendering pipeline and serverless rendering support. Look out as we release the missing puzzle piece in our vision of programmatic video!

We are excited to announce a packed October release! We did work in many areas and these improvements will surely boost your productivity!

In/Out markers

You may know this feature from programs like After Effects and Davinci Resolve already. It is as simple as it is useful: You can set an “In” mark and an “Out” mark and the preview will only play whatever is in-between those timestamps. This makes it much easier to visually “debug” a section of the video without having to watch the whole thing.

Thanks to Ankesh for implementing this feature!

<Loop> component

Previously, in order to repeat content, you had to manually create a bunch of sequences and calculate the timestamps yourself. We added a helper called <Loop /> which will repeat it’s children either indefinitely or for a fixed number of times. Another benefit is that we display the loop component cleanly in our timeline.

Thanks to Brian Pederson for implementing this feature!

Support for different playback rates

You can now change the playback rate in the editor and play a video in slow-motion, in fast-forward, and even in reverse! We support speeds between -4x and 4x. This makes debugging animations that don’t look clean much easier.

It also works in the <Player />! See the new playbackRate prop and we also added a ratechange event - just like the native HTML5 Video element.

Thanks to Brian Pederson for implementing this feature!

Support for J, K, L keyboard shortcuts

These new shortcuts are super handy for navigating through a timeline. With the L key, you play the video as normal. Pressing the L key again will increase the speed to 2x, and pressing L three times in total will play the video in 4x.

The J key works the same, but plays the video backwards. Now you can reach any point in the video easily with just those two keys, even if the video is playing, without using the mouse.

Once you have reached the point where you want to pause the video and continue to code it, the K key will reset the playback rate to 1x and pause the video.

Once you learn how to navigate using JKL keys, you'll never use your mouse for scrubbing again!

Thanks to Brian Pederson for implementing this feature!


Press the ? button to learn about all keyboard shortcuts!

durationInFrames={Infinity} is now optional

If you wanted to delay an element but not cap it’s duration, you had to explicitly specify durationInFrames={Infinity} . Not anymore! This is now the default and may be omitted. If you upgrade the @remotion/eslint-config package as well, we will even automatically remove the prop when you have autofix enabled!

Thanks to Khalid Ansari for implementing this feature!

Fig autocomplete

In case you don’t know Fig, it is a free macOS application that provides autocomplete for the terminal. What sounds like a gimmick, actually works surprisingly well and I personally would miss it a lot if I didn’t have it! The Remotion CLI that you can invoke using npx remotion now has full autocomplete support in Fig! You have to do nothing except install Fig.

Thanks to Mattèo Gauthier for implementing this feature!

Node.JS 17 support

This version came out recently and broke almost every Webpack project because legacy crypto functions were removed.

We added the necessary modifications to our default Webpack config, and even contributed a pull request to Webpack to fix the last remaining bug that would break Remotion with Node 17! If you are upgrading Node, definitely make sure get this new version of Remotion.

Monorepo migrated to pnpm

Contributors to Remotion would previously often struggle to correctly set up our monorepo. Indeed it was hard to correctly link all the packages and too easy to mess it up and run into error messages.

This is why we are happy to have migrated to pnpm, which gets rid of the linking problems and also speeds up installation significantly. In your CI systems, we saw build times go down by 40%, which allows to iterate much more faster.

Thanks to Sergio Moreno for implementing this migration!

“Empty” template

A new template has been added to npm init video / yarn create video: The blank template. This template contains only the bare minimum Remotion boilerplate and a completely empty canvas. It is especially useful for people already familiar with Remotion who would like to skip deleting the Hello World project every time.

Thanks to Aneesh Relan for creating this template!

Render video to out folder

Previously by default, a video would be rendered to out.mp4 in the root directory of your project. This also meant that in order to ignore it from Git, we had a complicated .gitignore by default that would ignore video files in the root but inverse-ignore other video files. Time to simplify: From now on, we render a file into an out folder by default and simply ignore that folder.

Thanks to ahmadrosid for implementing this feature!

Updates to @remotion/three

A few interesting updates for users of @remotion/three:

  • The Three Canvas is now wrapped in <Suspense> and the render is delayed until the content has been loaded (unsuspended). This works better with the React Three.JS ecosystem and now components such as drei’s <Environment /> component will work out of the box.
  • We now default to the angle OpenGL engine for Google Chrome, which we, through empirical testing, have found to have the best overall support for Three.JS content across platforms.

More updates

  • Added support for OTF fonts - Thanks William Candillon!
  • Added possibility to customize <Player> error message - Thanks AudreyKj!
  • Windows Node.JS 14 cleanup bug fixed - Thanks Raznov!
  • Upgraded Docusaurus to the newest version, obtaining the newest features and layouts

Hacktoberfest Roundup

We opted into participating in Hacktoberfest, and put $100 bounties on 11 issues as an extra incentive! Every single of those issue has been picked up and solved! Every contributor did a great job, many greatly surpassing our expectations!

Thank you everybody who participated and contributed to this release!

In this release, we are revamping the Remotion Preview interface to make it easier on the eyes and add new features. While Remotion will always be about leveraging code instead of clicking buttons, we want to add complementary helpers to help you get your videos done faster!

New toolbar

All the actions that can be performed in the editor are now organized in a toolbar at the top, plus we added quick links to resources such as Documentation, Changelog, GitHub, Support options and our social media accounts (follow us over there!).

"New composition" helper

You can press N to bring up a modal that helps you generate code for creating a new <Composition /> or <Still />. Drag the sliders to quickly adjust the dimensions and duration of the video. Lock or unlock the aspect ratio. Click the numbers to enter an exact value. Receive warnings on invalid configuration. Once you are happy with the code, you can click the copy button and paste it in your src/Video.tsx file.

"Keyboard shortcuts" pane

To get an overview of all keyboard shortcuts, you can now press ? to bring up a list of all shortcuts.

Improved keyboard navigation

For those true hackers that don't use mouses, we optimized the whole new UI to be usable with just the keyboard. Use the Tab key to focus items, the arrow keys to navigate through menus. Press Enter or Space to click on items. Use Escape to quit modals and menus.

Built with 0 dependencies

We want to add new features to the Preview, but not bloat Remotion by adding tons of third-party packages that increase startup time and at some point will cause you to fight with your package manager. So we carefully crafted the editor with no dependencies except React and Remotion (which also only has react and react-dom as it's only dependencies).

Other improvements

  • New <Series /> component: Introduced in 2.3.2, we added a new <Series /> component that helps you layout many sequences in a row. See this post (Instagram | Twitter) for additional infographic explanation!

  • Better handling for browser autoplay policies: If you use the <Player /> and include audio in it, you might hit a browser limitation where audio cannot be played because of a browsers autoplay policy. Remotion can now avoid some of those scenarios by playing some silent audio when the user actively triggers a play on the Remotion Player. If you then later in the video want to play some audio, Remotion will route that audio to an <audio /> tag that was already playing silent audio and was already freed from the playback restrictions of the browser. You can control the amount of silent audio tags that Remotion should place using the numberOfSharedAudioTags prop.

  • Better handling of invalid dimensions: It turns out that MP4s can only have even dimensions. So while a 1000x1000px MP4 is completely fine, a 999x999px MP4 is not possible according to the spec. Instead of erroring out when rendering, we now warn you early using a new ESLint rule, and also when you use the "New composition" dialog.

  • Bug fixed when using frameRange: A one-off error would cause the wrong frames being rendered when using the frameRange option. If you specified a frame range of 0-20, the frames -1 until 19 would be rendered. This is now rectified, if you were reliant on this option, please make sure your video renders as intended after the update!

  • Component mounts directly at desired frame: During rendering, previously the browser would always mount the React component at frame 0, and then update the component with the initial frame that should be rendered. This is now changed, so if you are e.g. using the frameRange option to render frames 20-39, your component will now never mount at frame 0 after this update.

Up next

We are working on revamping the rendering pipeline and adding more ways to render a Remotion video and plan to release this as a major version bump (v3.0) with some breaking changes. Stay tuned for announcements on how we make Remotion much easier to scale.

Remotion 2.3 is out and features first-class support for still images!

So far we focused on streamlining the workflow for making videos. While it was always possible to render out a single image instead of an encoded video, we have optimized this use-case in this release.

New <Still /> component

This new component is the same as <Composition /> but is meant for defining a compositions that output a still image. Since it's already implied, you don't have to define the fps and durationInFrames properties.

title: "Welcome to Remotion",
description: "Edit Video.tsx to change template",
slogan: "Write videos\nin React",
title: "Welcome to Remotion",
description: "Edit Video.tsx to change template",
slogan: "Write videos\nin React",

Optimized editor for stills

There are now icons in the sidebar for compositions, and those who are stills have an image icon.

Now still images (compositions with a duration of 1 frame) are marked with a special icon.

For still images, you don't need the timeline, so it will hide itself and give you a bigger canvas.

New remotion still command

Rendering stills has become easier as well. The new remotion still command allows you to quickly generate a PNG or JPEG on the command line.

npx remotion still --props='{"custom": "data"}' src/index.tsx my-comp out.png
npx remotion still --props='{"custom": "data"}' src/index.tsx my-comp out.png

New renderStill() API

If you render using the Node.JS APIs, we have a new equivalent API for rendering stills as well.

await renderStill({
serveUrl: bundleLocation,
output: "/tmp/still.png",
inputProps: {
custom: "data",
await renderStill({
serveUrl: bundleLocation,
output: "/tmp/still.png",
inputProps: {
custom: "data",

New Stills template with server rendering

We have made a new template that includes a social media preview card and a server that you can customize and easily deploy to the cloud. We have tested it on DigitalOcean and Heroku and have added instructions on how to deploy it.

We use this service to generate the social preview card for the blog post you are reading right now. Feel free to go to this URL and play around with the parameters:,%20renderStill()%20API,%20optimized%20editor%20and%20CLI,%20Server%20rendering%20template

The server includes different caching options, rate limiting and limits to 1 render at a time, so hopefully it's ready for production. We put the URL out there for you play around with it, should there be any unexpected problems, we'll fix the template.

🔜 Serverless in the works

We are also working on getting still image rendering working in a serverless environment and providing a framework for it. We aim to launch it this fall - if you are interested in testing an early version, write us a message in our Discord.

yarn create video now has multiple templates

When creating a new video, you now get to choose between different templates, that give you a great starting point for your usecase.

In addition to the default template and the previously announced Three.JS template, there now is also a plain-JS template, a text-to-speech template and the above mentioned Stills template.

Player now supports space key to play/pause

The <Player /> component now supports the new spaceKeyToPlayOrPause prop to toggle the video playback. We designed it with focus management in mind so it behaves well when multiple players are on the same page. This prop is by default true.

Welcome to the release notes of Remotion 2.2! It's been a while since v2.1, but in the meanwhile we had a dozen smaller releases inbetween. This post summarizes the highlights of the past 2 months 🎉.

Environment variable support

We developers use environment variables extensively to manage configuration, secrets and other stuff you don't want to commit to a GitHub repo. If you write videos with code, environment variables are useful too!

We added support for environment variables from the CLI, using a .env file, and allowing you to pass environment variables via our Node.JS APIs too. Click here to learn more.

<Freeze /> component

This new core component will freeze all of it's children and make them think that the video is paused at a certain time.

You can use it for example to display a still frame from a video:

import {Freeze, Video} from 'remotion';
import myVid from './vid.mp4';
export const MyVideo = () => {
return (
<Freeze frame={30}>
<Video src={myVid} />
import {Freeze, Video} from 'remotion';
import myVid from './vid.mp4';
export const MyVideo = () => {
return (
<Freeze frame={30}>
<Video src={myVid} />

However, it works for any content. As you can see the API is dead simple! You can combine it with the <Sequence> API to make any content play, pause and then continue again.

Read the docs for the <Freeze /> component here.

Video + Audio playbackRate

This prop allows you to slow down or speed up video and audio elements! Now you can import a video in normal speed and play it in slow motion or timelapse without re-rendering the video.

import {Video} from 'remotion';
import myVid from './vid.mp4';
export const MyVideo = () => {
return (
<Video src={myVid} playbackRate={4}/>
import {Video} from 'remotion';
import myVid from './vid.mp4';
export const MyVideo = () => {
return (
<Video src={myVid} playbackRate={4}/>

While previewing, we are using the HTML5 playbackRate API, and when rendering, we will calculate the correct FFMPEG command for any tempo.

Learn more about the playbackRate props for <Audio /> and <Video />.

@remotion/three package

In case you missed it, we released a new helper package for React Three Fiber!

0:00 / 0:10

Three.JS is admittedly not easy, but with the work that Poimandres is doing to make it more approachable and more integrated with React, this is changing rapidly. Creating 3D videos in React and rendering them to real MP4 videos, we are making it possible!

Learn more about @remotion/three and get started using our template.

ProRes support and MKV support

Creating MP4 videos with React, that's just our marketing tagline. We support a lot of other codecs too, like H265, WebM, and even transparent WebM!

We are adding two more codecs:

  • ProRes is a codec suitable for video editors using Final Cut Pro, Adobe Premiere or Davinci Resolve. Say you want to create an overlay animation using Remotion and use it in a traditional video cutting program, you can now use ProRes to export the video with an alpha channel and import it to many other programs losslessly.

  • The Matroska container format (which can be recognized using the .mkv extension) is a format that commonly also just contains the H.264 videos, the same codec used for MP4s. However it has more flexibility for audio and allows lossless audio streams to be contained by the format. MKV support will come in handy for an upcoming Remotion feature, and is the first step in allowing us to go to the moon.

Read the Encoding guide to see an overview of all options.

<Player /> updates

The @remotion/player, currently still experimental, allows Remotion videos to be played on the web without having to encode them. We've made the following progress towards getting it stable:

Audio controls

A player now has a volume slider, and a mute button to allow the user to control the video. You can decide whether you want to display these controls using the showVolumeControls prop.

Audio can also be controlled programmatically. We added the methods getVolume(), setVolume(), mute(), unmute() and isMuted() to allow you to implement your own solutions.

timeupdate event

Inspired by the HTML5 event with the same name, we added a timeupdate event to the Player. Unlike the seeked event, it does not fire on every frame, so if you want only periodic updates about the time being updated, you can use this event without having to throttle it.

clickToPlay prop

This prop allows you to control whether the user is allowed to click on the video to make it pause or play. It is true by default if the controls of the player are enabled.

doubleClickToFullscreen prop

This prop allows you to control whether the user is allowed to double click on the video to make it go fullscreen. If enabled, single-clicking to pause the video will have a short delay in order to wait for a potential second click.

Timeline scroll position gets persisted

When coding a video, and refreshing the preview, the video would jump back to the first frame which was annoying. Not anymore - if you refresh you are back where you left off!

Remotion waits for fonts to be loaded

If a Webfont gets loaded via Google Fonts, it would be loaded using font-display: swap, which means Remotion would sometimes render a frame before the font is loaded. Now we use the document.fonts.ready browser API to make loading webfonts completely seamless for you.

Specify a custom --port

By default the Remotion preview starts a server on port 3000. Should you want to have it start on a different port for any reason, you can now pass a CLI flag.

More helpful error handling

We want to help you out whenever you are facing a tricky issue. Here are some examples of scenarios where we now give you a helpful warning and linking to the documentation:

  • Multiple versions of Remotion are imported on a page (for example when using the <Player /> in your app)
  • A video is loaded that does not support seeking (for example when serving from Google Cloud Storage)
  • A video with an unsupported codec is loaded (for example an MP4 in the Chromium browser)
  • A delayRender() handle has been created but never cleared

Documentation upgrades

We now have a search at the top right of the docs! Thanks to Algolia for hosting the widget and indexing the documentation.

Type hints

Did you notice it in the snippets above? You can now hover over any symbol and see it's type. It's powered by Typescript + Twoslash. A really nice side effect is that it's now impossible for us to make typos in the documentation since all snippets are type checked.

Troubleshooting guides

We now have help articles on various issues that you may face. Currently we have written about 6 common problems, and put them in a new section of the docs called Troubleshooting.

Page about third party integrations

A new page has been created listing some popular libraries and describing how well they work together with Remotion - or don't.

New landing page

Finally, the homepage of Remotion got a makeover! We hope to better communicate what Remotion is and why it's awesome.

This releases features new utility functions, improved developer experience and an experimental release of the Remotion Player!

New interpolateColors() function 🌈

Now you can easily animate between colors and mix colors to create interesting animations using interpolateColors().

I personally used it to recreate Apple's 'Spring Loaded' logo in Remotion using only <div> elements.

Thanks for Shankhadeep Dey for implementing this feature!

New measureSpring() function 🌀

One problem when using a spring animation for transitions is that you don't know the duration of the animation. This is why we added a new measureSpring() function!

Now you can adjust your timings in Remotion dynamically when changing spring configurations.

Thanks to Samuel Rodriguez-Lozano for implementing this feature!

Documentation and developer experience updates

We invested time in making sure that if something goes wrong, you don't get stuck. Here are some things we did to improve your experience with Remotion:

  • If you encounter a timeout, you will now see a stacktrace of where the delayRender() handle was not cleared. We also now have a troubleshooting page for timeouts and link to the documentation if you encounter the error.
  • If you use Chromium and import an MP4 video, you get a more helpful error and we link to a help page.
  • We added a guide for improving performance while development and while rendering.
  • The server-side rendering APIs bundle(), getCompositions(), renderFrames() and stitchFramesToVideo() with all their parameters are now more properly documented.
  • If an exception is thrown while rendering, the log output in the console is now better.

Alpha release of @remotion/player

We are working on a Remotion player component that you can import into your React app. Today we are prereleasing the player for those who wish to experiment and provide us with feedback. Let us know what you think!

This is our biggest and best release so far - today we are unloading a lot of awesome, highly requested features!

Audio support

We are happy to ship audio support with a flexible API!

You can import one or multiple audio tracks into your project, cut, trim and align them in your composition. The volume can be controlled for the entirety of a track, or you can control it frame by frame to create fade effects and much more. Apply your React mindset - Remotion doesn't care how you render the audio tag, just that it's there. The mechanic of how we tell FFMPEG to mix the audio just like you hear it in the browser preview is really complex and was challenging to build - we are very proud of the outcome!

Audio visualization

With newly introduced audio visualization APIs, you can make your visuals react to the frequency of the audio.

What you need are the new getAudioData() and visualizeAudio() APIs that have been published in it's own package.

Read more about audio visualization in the docs or watch a sample video (the source can be found here).

Export as MP3, AAC, WAV

You can now also completely omit the video from the output and only emit an audio file. Yes, Remotion can also be used as an audio editing program! Pass mp3, aac or wav as a codec using the --codec flag or in your config file.

@remotion/media-utils package

This is a new helper package which includes functions useful for dealing with audio. Besides audio visualization, you can also for example measure the duration of an audio or video source, which is really useful for making a composition duration dynamic. The functions included are getAudioData(), getAudioDuration(), getVideoMetadata(), getWaveformPortion(), visualizeAudio() and useAudioData().

All of them except the last one are completely independent from the ideas of Remotion, so they might be a great fit for your other non-Remotion projects as well! This package is MIT-licensed, so you everybody can use it without obtaining a company license.

Rich Timeline (experimental)

With the normal timeline, you don't see the full picture of all the media that you have placed in your composition. The reason is that the visualization you see is based on what's currently rendered at the position of your playhead.

Introducing a new timeline mode: The rich timeline will render additional frames other than the current one to gather enough information to visualize a full timeline. Sequences which are normally not rendered because the playback head is not within the time range of the sequence, will appear because Remotion is doing an additional render at a time where the sequence is visible.

By default the rich timeline feature is disabled, but will be enabled by default if the feedback is good. You may switch between the rich timeline and simple timeline by clicking the icon with the three lines. Try it out and let us know what you think!

ESBuild loader

The traditional transpilation of Javascript and Typescript using babel-loader has been replaced by the faster esbuild-loader by default.

This will speed up bundling by a lot - hopefully you won't notice any other differences! If you for some reason need to go back to the previous behavior, you may override the Webpack config - we are releasing a helper that makes it easy.

Webpack caching

Even though transpilation is done using ESBuild now, Webpack is still being used for bundling. We rely on Webpack features such as Hot Module Replacement, asset importing, it's strong loader ecosystem and now it's caching features.

When you run npm run build for the first time, you will get a message that a cache is building. From the second time on, bundling will be much faster, even if you change your code. You shouldn't have to ever do it, but you can opt out of caching.

Partial video rendering + Stills

Want to render partial video or a still for thumbnail? You can do that with Remotion 2.0. We introduced a new CLI flag --frames to render a subset or a still of a video.

--frames=0-9 (To select the first 10 frames) or --frames=50 (To render a still of the 51st frame).

Learn more about the --frames CLI option.

@remotion/gif component

A new GIF component released in the @remotion/gif package is now available. The <Gif /> component allows to load a local or remote GIF and synchronizes it with Remotions useCurrentFrame(). For that it parses the GIF using WebAssembly - basically it's really cool tech! Thanks a lot to @jeetiss for contributing this new component.

Learn more about the GIF component here.

Resizable editor panels

In the editor, you can now resize the timeline as well as the left sidebar. Thanks a lot to Arthur Denner for this awesome contribution!


interpolate() now supports arrays with lengths bigger than 2. Really useful for a lot of scenarios - for example you can create a combined fade in/fade out transition with one line.

const opacity = interpolate(
[0, 10, durationInFrames - 10, durationInFrames],
[0, 1, 1, 0]
const opacity = interpolate(
[0, 10, durationInFrames - 10, durationInFrames],
[0, 1, 1, 0]

170+ tests added

While not strictly a new feature, this is definitely worth mentioning.

Calvin Falter, Jonas Brunner and Tobias Boner took Remotion as their project for their university seminar and contributed over 100 tests, strengthening the code and ironing out edge cases.

@cnnr contributed a really cool end-to-end test that tests the video seeking of Remotion and makes sure it is frame-accurate by matching the colors in each frame.

The remaining added tests are testing the tricky parts of audio rendering. Thanks to test-driven development, we've been able to catch regressions and ship really solid audio support.

The bottom line: In Remotion 1.5.4 we had total 43 tests, in Remotion 2.0 we added a total of 174 tests to come out at a total of 217.

<Video/> and <Audio/> have startFrom and endAt props

These new props make it easier to cut the start or the end of the video. This is implemented using sequences, which was also possible before, but this is a convienient shorthand.

Fixed: Frame seeking

In Remotion 1.x, a <Video/> would not always perfectly synchronize with Remotions time during render. This is now fixed and validated by tests that scan the color of the output frames - however not in the most efficient way. Help on improving it further is still welcome.

Fixed: Timeouts while importing large videos

Importing files into your webpack bundle that were of significant size (the problems started at around 40MB) led to slow renders and timeouts. This is now fixed by swapping out dependencies and making sure the whole stack supports the HTTP range header well. Now if you seek a video, only the necessary parts will be loaded from the filesystem rather than the whole file being read.

Breaking changes and upgrade

We've taken this opportunity of a major release to introduce some breaking changes that we think are beneficial for an awesome future of Remotion. Please take a moment to read through the 2.0 Migration guide and see if you are affected.

The future

Most of the core functionality for making videos in React is now implemented. This gives us time to focus on improving all the areas around it - we are talking better documentation, developer experience, examples, abstractions on top or Remotion, improving speed and reliability of Remotion.

Furthermore, we want to provide a way to embed Remotion compositions in traditional web apps and to make server-side rendering easier - stay tuned!

This release contains no big new features, but addresses some common problems.

No Chromium download necessary

Until now, every time you ran yarn create video, a binary of Chromium was installed, which was slow and took a lot of space (between 170-280MB depending on the OS). Making matters even worse, these binaries would not include the codec required to play MP4 videos, meaning if you wanted to embed one, you had to convert it to WebM first.

Now Remotion will try to find an existing installation of Chrome on your machine and if it finds one, it will use it and skip the download. If it doesn't find one, you can specify the path using the setBrowserExecutable() option or the --browser-executable command line flag.

If you are running Remotion on a machine where neither Chrome nor Chromium is installed, Remotion will still download a version from the internet. However, the download only happens when you invoke npm run build for the first time, so you don't have to wait so long before you can start experimenting.

Improved Apple Silicon and WSL support

Apple Silicon support is another nice side-effect of the Puppeteer refactor, since previously the installation would fail because no Chromium binaries were available for the Apple Silicon architecture. Now that Remotion will try to use the local Chrome installation this is way less likely to happen.

On Windows Subsystem for Linux, a missing flag would lead to Remotion getting stuck during rendering. This is now fixed. Linux users also need to install some additional libraries, which is now documented.

Smoother timeline

Why would the timeline of your 30 FPS only play at 28.7FPS? Turns out it's a bug that was investigated and fixed by yuta0801! Now the playback during preview is smoother and the FPS counter is way more likely to display a number matching your desired FPS.

Failing to render a frame fails hard

If a frame fails to render for some reason (such as calling delayRender() and never resolving the lock), this will now stop the rendering process. Previously you would get an error message but Remotion would keep trying and keep failing.

Rendering will happen on a localhost server

Previously during rendering, frames would be opened via file:// protocol and get screenshotted. Now the frames are being served on http://localhost:3000 (if port is not available, it will try 3001, 3002, etc.), which is the same behavior as in the preview.

Now APIs can now simply whitelist localhost domains in their CORS configurations, and you can more easily use those APIs to feed data into your video.

New tutorial: Programmatic Instagram Stories

In case you missed it, I released a new tutorial showing the workflow of how to programmatically create Instagram Stories with dynamic content. You can watch it here.


As always, you can upgrade to the newest version by running npm run upgrade in your Remotion project.
