I believe this should be a viable routine for two-pass encoding using libx264,
but it fails, as shown. A similar command to encode the same video source file
using libx265 with Matroska output is successful, so I don’t think the source
file is the culprit. Both the x264 and x265 encoding report

I'm trying to convert 30 fps videos to 24 fps. I've been playing with a lot of

How do I specify an output format? I did not do that in the original command

Maybe you would benefit from using “h264_videotoolbox” rather than “libx264”.

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.

Please tell me how ffmpeg may be used to correctly detelecine the source so
that the output compares
qpmin=8:qpmax=28:qpstep=4
'2023ffmpeg_telecine..m4v’” when I changed it from the above after resorting to
wild guesses, but please consider the above as what was used, because it yields

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