Hi,
when encoding an 8bit grayscale video using the commandline
# ffmpeg.exe -f rawvideo -vcodec rawvideo -pix_fmt gray -s 1280x960 -r 30 -i
out8.yuv -c:v libx264 -qp 0 -preset ultrafast -y out8.mkv
and decoding using
# ffmpeg.exe -i out8.mkv -f rawvideo -c:v rawvideo -pix_fmt gray -y

Hi,
my input is a video with an included audio track.
I need to convert the video to a prores quicktime and extend the audio
track to the length of the video.
In the ffmpeg documentation I found the apad filter.
Since I need to apply several filters I am using filter_complex to

[0:v]setpts=((24000/1001)/24)*PTS[outv];[0:a]apad[padded];[padded]atempo=(24/(24000/1001))[outa]
Your filter graph is not connected (setpts and apad+atempo are not connected
together by any link). This is not a good
