ProRes 4:4:4 output High Bitrate

  • Hey ya

    Just started using Voukoder (Great plugin by the way!), and on testing a ProRes 444 output from Media Encoder and the video bitrate is rather high compared to that of a direct ffmpeg output, and the target bitrate value in the Apple ProRes specification.

    At 25p the target bitrate is 275 Mbps (1920x1080), Voukoder is outputing 402 Mbps according to mediainfo. The same source media run through ffmpeg outputs with mediainfo at 285 Mbps.

    Voukcoder output:

    Direct ffmpeg output:

    cheers

    I did some testing and I compared the "Bit Rate" entry in both MediaInfos of ffmpeg and voukoder. In the end voukoder was even lower than ffmpeg.

    I had to disable all filters and side data entries in voukoder. I also had to set Color Range to Limited, because it is most likely limited in the source material.

    In the end I had:

    Voukoder: 1 067 Mb/s

    FFmpeg: 1 226 Mb/s

    Maybe it is also related to the alpha channel compression.
