Hello all,
This is my first post, hopefully all the pertinent info is included to get
some assistance.
I'm trying to clip a XAVC file on MacOS 10.15.2. In the past, I've used
ffmpeg to pull clips from large files so I don't have to pull the whole
file into iMovie and clip it there. I just started using the higher quality
XAVC files, but seem to be running into codec issue.
First attempt bombs out with codec pcm_s16be in stream #1, codec not
currently supported in container.
ffmpeg -i C0003.MP4 -ss 00:06:15 -t 00:00:15 -c:v copy -c:a copy
/tmp/clip.MP4

I found another thread that suggested converting to MKV. This completes,
however the audio is terrible when played back through VLC (the clip won't
open with quicktime 10.5: the file isn't compatible).

Any suggestions on different syntax, codec, conversion process is welcomed!
