We're taking video even more seriously with our own multimedia library, designed from the ground up for JavaScript and the web!


Remotion Media Parser Docs

In short, what does Remotion Media Parser achieve?

Better metadata retrieval

Get more information from more file formats, faster. An universal API that works on both the server and the client.

You can choose which metadata you want to retrieve, and Media Parser will choose the fastest way.

Get metadata from a video
tsx
const result = await parseMedia({
src: 'https://parser.media/video.mp4',
fields: {
durationInSeconds: true,
dimensions: true,
fps: true,
slowKeyframes: true,
slowVideoBitrate: true,
isHdr: true,
videoCodec: true,
rotation: true,
numberOfAudioChannels: true,
sampleRate: true,
metadata: true,
},
});
 
console.log(result.durationInSeconds);
(property) durationInSeconds: number | null

Video decoding and processing

Media Parser ties into the WebCodecs API – hardware-accelerated decoding, built right into the browser. Previously hard to use, now made accessible!

Video decoding
Decode video frames
tsx
const result = await parseMedia({
src: 'https://parser.media/video.mp4',
onVideoTrack: (track) => {
const videoDecoder = new VideoDecoder({
output: console.log,
error: console.error,
});
 
return (sample) => {
videoDecoder.decode(new EncodedVideoChunk(sample));
};
},
});
note

This is an oversimplified example - you might get performance problems running this code with longer videos because samples are being passed faster than they can be decoded.

Unlock new use cases

WebCodecs use cases

Developers need a better way to work with video on the web.

Media Parser is a foundational library that unlocks many upcoming improvements to Remotion and for the web in general. We will be implementing many of these ideas ourselves, but also invite you to build with Media Parser.

We built the fastest video converter on the web

Try out remotion.dev/convert, our web video converter powered by Remotion Media Parser and WebCodecs. Because it works offline and the conversion is hardware-accelerated, it is faster than any other web converter we could find!
