The syntax is hard to understand if you've never written complex filter graphs before for FFmpeg.This will cause transcoding to occur, so it takes time and may degrade the quality.This method can concat videos with different encodings.Using a complex filter graph with the concat filter There are very few encodings that can do this, the only one I've used is MPEG-2 Transport Stream codec (.ts).There are some encodings that support file-level concatenation, kinda like just using cat on two files in the terminal.This method only works if the files have the same video and audio encoding, otherwise, artifacts will be introduced.This method is very fast as it avoids transcoding.There are three methods I have found thus far: It turns out, that is rather simple to do with FFmpeg. I would like to achieve the same result with either a frozen last frame or simply a black frames.I have found it very useful to concatenate multiple video files together after working on them separately. The result would then be a video file where the last frame just freezes but the audio still plays along.

I thought that this must be possible somehow, since I can also combine a large audio file and a small video with ffmpeg. So I tried to only use the audio track from input 1 ( ) but unfortunately, I'm getting this error message: Stream specifier ':v:0' in filtergraph description concat=n=3:v=1:a=1 matches no streams. I tried to do it with the following command: ffmpeg Is it possible to concatenate multiple files, if some of the files are videos with audio and some are audio only.
