Take another look at the separator before sub-second time to see if they really are both “:” > I'm not familiar with the -f option and didn't immediately find it in the > FFmpeg documentation > How does that work? It sets the output file format, overriding what is guessed from the filename extension. There are some subtle (and some not so subtle) differences between quicktime, iso base media and mp4 formats. Files with timecode and edit list from an NLE, sometimes with references to external files = qt in my mind. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

I'm not familiar with the -f option and didn't immediately find it in the FFmpeg documentation How does that work? Tried simply switching to the .mov extension instead of .mp4 The tracks mapped properly, the quality is good, and -- though it didn't occur to me until your suggestion -- .mov is preferable to .mp4 for our workflow. So thanks for the suggestion. An "obvious" idea that only became obvious after you suggested it. BUT for some reason the time code changed. So a clip that had started at TC start/end of 12:31:20:13 / 12:31:42:16 converted to 12:30:35:12 / 12:30:57:15. Duration matches, frame rate matches, but the start/end TCs are earlier by 45:01. > On Feb 13, 2019, at 10:57 AM, Gyan wrote: > > unmap the data streams, > > -i '/Path/To/ProRes/Source.mov' -map 0 -map -0:d -g 48 -c:v libx264 > -profile:v baseline -crf 16 -c:a aac -b:a 256k -vf scale=1280:720 -pix_fmt > yuv420p '/Path/To/Mp4/Dest.mp4' Gyan -map -0:d fixed the problem entirely. Audio Tracks are good / TC is good both for .mov and .mp4 Any idea why failing to un-map the data streams causes the time code to change? Thanks to both of you.
