ProRes bits per macroblockv4.0.543

Set the bit budget per macroblock for software ProRes encoding. Accepts an integer from 128 to 8192. Lower values can reduce file size and quality; higher values may produce the same output depending on the content and ProRes profile. Default: null, which lets the encoder choose based on the profile. This maps to FFmpeg's -bits_per_mb option for prores_ks and requires the prores codec. With hardwareAcceleration set to if-possible, encoding falls back to software; required is not supported. The ProRes profile and pixel format still determine the output format and alpha channel support.
