Keeping “-an” for first pass, then using “-c:a copy” for second pass makes
sense to me, or am I completely wrong?

How do I specify an output format? I did not do that in the original command
where the size was also changed and it still made the mp4 format...
Maybe you would benefit from using “h264_videotoolbox” rather than “libx264”.
Could you provide an example .ts video?

Thanks. I’m not having any trouble with it
Is there a change to cropdetect in ffmpeg v.4.1.4_1? I've been using “ffmpeg -i
input -t 1 -vf cropdetect -f null - 2>&1 | awk '/crop/ { print $NF }' | tail
-1” for a long time, and now it appears to yield no output. Thanks.

BTW, -vf pullup -r 24000/1001, doesn’t work on the clip
(https://dl.dropboxusercontent.com/u/42718751/2024_telecine_source.zip),
either, when I used "ffmpeg -i 2024_telecine_source.mpg -vf pullup -r
24000/1001 2024_ffmpeg_detelecine.m4v.”

MacUpdate. When I saw a similar issue in Mencoder output, I discovered that
"-lavfopts format=mp4” appeared to solve it, but even with an ffmpeg
equivalent, it would mean re-encoding, of course.

Please tell me how ffmpeg may be used to correctly detelecine the source so
that the output compares favorably with the mencoder output
Thanks.
