’ve got a question about the Prores implementation in ffmpeg because I’ve seen some odd behavior here with FCPX (running on a very beefy 16-core Mac Pro with 192Gram and an Afterburner card).
When I output files from ffmpeg in ProresLT format and bring them into FCPX, they stutter badly… playback is ~5fps. But when I transcode/optimize them in FCPX, which creates Prores422 versions of those files, they play back in FCPX seamlessly. The ffmpeg files _used_ to play back seamlessly on this machine when I was doing this Jan-March, but I haven’t been using this workflow since March. My questions are: 1. Is the Prores implementation in ffmpeg a 100% accurate implementation as per the Apple spec? 2. Has anything changed in the Prores code transcoding of ffmpeg in the lat 4 months? Thanks! -g _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
