Transcoding for better performance and easier editing



  • @iFang "Is there any open source software that will convert a MP4 h.264 file to MOV ProRes or Cineform?"


    Yes. Seriously, read this thread.


  • @NormanPCN I can't find a single comment mentioning about an open source software that can convert to ProRes on Windows machine.

     @iFang ProRes isn't the codec you should be using for Windows. You should be using Cineform--something stated multiple times in this thread. 

    If you insist you can use FFMPEG and Avanti as described here.

    But here's someone else's article on why you shouldn't do that. TL/DR: ProRes is a commercial codec and any Windows encoders you might find are reverse-engineered hacks, arguably illegal, and likely to not work well--pointing back to the FFMPEG/AVANTI method above, where, multiple times the author says something like "the actual instructions didn't work, I had to do this instead."

    So. If you want to do ProRes through FFMPEG, there's your link. If you do this and discover any problems with those files the answer to all future questions from you on this topic is "use Cineform."

    I'll add a link to some ffmpeg Windows scripts that can be used to do easy transcoding to DNxHD, DNxHR and Prores. The ZIP has a contained readme text file.
