No more! joining different short recordings in one long document is generally done by a portion of the product accessible on the web. Be that as it may if you've attempted to physically blend recordings before using FFmpeg merge audio and video, you may realize how troublesome this can be. Video:18420kB audio:949kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.Merging loads of short video cuts into one longer video document can be a good thought. Non-monotonous DTS in output stream 0:0 previous: 2872469, current: 844047 changing to 2872470. This may result in incorrect timestamps in the output file. Non-monotonous DTS in output stream 0:0 previous: 2872468, current: 843791 changing to 2872469. Non-monotonous DTS in output stream 0:0 previous: 2872467, current: 843535 changing to 2872468. When merging the 2 files with the first method this is what i get : Non-monotonous DTS in output stream 0:0 previous: 2872466, current: 843279 changing to 2872467. There is the ffprobe of the two files : libavutil 55. So in my last attempt i tried to change the fps rate of my files like this : ffmpeg -y -i source.mp4 -r FPS -s RESOLUTION -c:v libx264 -b:v 3M -strict -2 -movflags faststart destination.mp4īut the result reduces the quality too much. The merge occur without any errors but the audio is still unsynch I loose the audio on the 60 FPS files, at this point i thought it was an audio problem so i tried to "unify" the audio codec of all mp4 files like this : ffmpeg -i input.mp4 -acodec SOME_AUDIO_TYPE -vcodec copy out.mp4 When trying the "mp4 to mpg then merge" : ffmpeg -i 1.mp4 -qscale 0 1.mpgĬat 1.mpg 2.mpg | ffmpeg -f mpeg -i -qscale 0 -vcodec mpeg4 output.mp4 The audio and video aren't synch anymore and the video sometimes freezes. When trying this method : :: Create File Listįfmpeg -f concat -i mylist.txt -c copy output.mp4 To merge the files i have been using all the solutions in this post I tried to modify the frame rate of the videos (30 to 60 or 60 to 30), but it reduces the quality too much. Most of the time the audio is not in sync with the video. When I merge the files, there always seems to be a problem with the output. I have been trying to merge some mp4 files with different frame rates without success.
