You must list the number of frames to loop (shown as 75 in the example above).This filter places all frames into memory.This example is the same as above but you don't have to manually make list.txt: for i in do printf "file '%s'\n" input.mp4 done) -c copy output.mp4Įxample using the loop filter to loop 4 times, each loop is 75 frames, each loop skips the first 25 frames of the input: ffmpeg -i input.mp4 -filter_complex "loop=loop=3:size=75:start=25" output.mp4 Automatically make list.txt in Linux/macOS If you want to add additional inputs make sure they all have the same attributes. Then run ffmpeg: ffmpeg -f concat -i list.txt -c copy output.mp4 Contents of an example text file to repeat 4 times. The concat demuxer allows you to loop an input without needing to re-encode because it can use stream copy.
This may not work with anything older than FFmpeg 4.0.0 means no loop, -1 means infinite loop.
