[FFmpeg-user] Is mixing of audio channels happening by default in ffmpeg?

[Wayne Poll]

When I use this process to convert Sony F55 XAVC 4k footage to Apple ProRes 422 (HQ) quick time files, the time code in the resultant quick time matches the original XAVC MXF time code perfectly, even when excluding the metadata track.

Sorry this is so late as a response (I've been away) but the fix is easy Sam; you can exclude the ninth track like this....

./ffmpeg -i input.mxf -map 0 -map -0:9:0 -c copy -c:v prores -profile:v 3 output.mov

The "-map 0 -map -0:9:0" will tell ffmpeg to copy all streams EXCEPT stream 0:9 - which in my case is a metadata track (possibly TC - not sure).

HTH someone...





Wayne,
Definitely another useful piece of information, thanks.
Unfortunately I *do* need the ninth track (TC) so the tracks must be specified explicitly.
