I don't quite understand how SARs of my videos both produced from 1280x720 pngs with the same FFMPEG parameters ended up having different SARs.įfmpeg.exe" -report -i test3.mov -i test-h264-jpg.mov -filter_complex " concat=n=2:v=1:a=1 " -map "" -map "" -start_number 0 -r 25 -vcodec libx264 -crf 15 -preset slow -profile:v main -pix_fmt yuv420p -ac 2 -ar 48000 -ab 320k -y concatted-mux.mov
Input link in1:v0 parameters (size 1280x720, SAR 1:1) do not match the corresponding output link in0:v0 parameters (1280x720, SAR 0:1) When I try to concatenate them using a custom filter I get this error: I've got two videos encoded from a sequence of png images and audio streams from mp3 with similar params.
