The output video concat.mp4 contains weird glitches and I get a lot of errors in console: Auto-inserting h264_mp4toannexb bitstream filter

With concat.txt file obviously containing: file 'middle0.mp4'īut this does not work. Then I concatenate videos: ffmpeg -y -f concat -i concat.txt -c copy concat.mp4 These two commands cut only middle part from each video, starting at 01.00 and ending at 04.00. What I am trying to do: ffmpeg -i 0.mp4 -c:v h264_nvenc -preset fast -rc vbr -qmin 1 -qmax 1 -filter_complex 'trim=start=01.00:duration=03.00,setpts=PTS-STARTPTS' -map middle_0.mp4įfmpeg -i 1.mp4 -c:v h264_nvenc -preset fast -rc vbr -qmin 1 -qmax 1 -filter_complex 'trim=start=01.00:duration=03.00,setpts=PTS-STARTPTS' -map middle_1.mp4 Both videos are exactly the same origin - same FPS and same codec. I have two videos, and I need to drop both ends for both videos and leave only middle part, and then concatenate middle parts together.
