As you did not share the output of your FFmpeg command there is
not much else than guesswork.

You did not ask for it, I did not know you wanted it, sorry. Which of them do you want, all? I'll post the one for libx264 that you suggested.

The list FAQ -clearly- says to post the entire command and unedited output.

You can simply ask politely and we simple users will provide all the 
information you need. :-)


ffmpeg version 3.4.14 Copyright (c) 2000-2025 the FFmpeg developers

It also clearly says to use the most recent if you can, 3.x is positively ancient! try something built in the last six months.

I have whatever the distribution provides. I have just looked and found 
ffmpeg-4, will try that one.

Well, you see, that's one reason for not updating the program. Scripts and 
recipes stop working.

I asked chatgpt about it. It said to try:

downconvert to 8-bit:

ffmpeg -t 10:0 -i movie.mkv -vf "scale=-1:802,format=yuv420p" \
-c:v libx264 -preset fast -crf 22 -tune fastdecode -profile:v main \
-c:a copy -c:s copy 1b_movie.mkv

keep the video 10-bit, use a compatible H.264 profile:

fmpeg -t 10:0 -i movie.mkv -vf "scale=-1:802,format=yuv420p10le" \
-c:v libx264 -preset fast -crf 22 -tune fastdecode -profile:v high10 \
-c:a copy -c:s copy 1b_movie.mkv



I'll try both.

Well, initial problem solved, thanks.  :-)


I still have the problem of having all subtittle streams copied. chatgpt says 
to use:

ffmpeg -t 10:0 -i movie.mkv \
-vf "scale=-1:802,format=yuv420p" \
-c:v libx264 -preset fast -crf 22 -tune fastdecode -profile:v main \
-c:a copy -c:s copy \
-map 0:v:0 -map 0:a:0 -map 0:s:0 -map 0:s:1 \
1d_movie.mkv

or

ffmpeg -t 10:0 -i movie.mkv \
-vf "scale=-1:802,format=yuv420p" \
-map 0 \
-c:v libx264 -preset fast -crf 22 -tune fastdecode -profile:v main \
-c:a copy -c:s copy \
1d_movie.mkv


These work, except that now the audio now doesn't work. VLC says:

Codec not supported: VLC could not decode the format "eac3" (A/52 B Audio (aka 
E-AC3)



Which is weird. When only one subtitle stream was copied, and the audio was 
copied, it worked.

Can you suggest a command line similar to

ffmpeg -t 10:0 -i movie.mkv -vf "scale=-1:802,format=yuv420p" \
 -c:v libx264 -preset fast -crf 22 -tune fastdecode -profile:v main \
 -c:a copy -c:s copy 1d_movie.mkv

that will copy all subtittle streams and doesn't make the audio to fail?


Command line output:

cer@Telcontar:/mnt/nfs/Isengard/xfsRaid/Videos/tmp> ffmpeg -t 10:0 -i movie.mkv 
\
-vf "scale=-1:802,format=yuv420p" \
-map 0 \
-c:v libx264 -preset fast -crf 22 -tune fastdecode -profile:v main \
-c:a copy -c:s copy \
