FFmpeg supports several additional lossless compressed formats such as: ffmpeg -i avatar35l.avi -vf 'movie=avatar35r.avi pad=1920*2:1080 overlay=1920:0 ' avatar35sbs.aviįfmpeg -i left.avi -i right.avi -filter_complex hstack -c:v ffv1 output.aviįfmpeg -i left.avi -i right.avi -filter_complex 'hstack,format=yuv420p' -c:v libx264 -crf 18 output.mp4įfmpeg -i left.avi -i right.avi -filter_complex 'hstack,format=yuv420p amerge' -map '' -map '' -c:v libx264 -crf 18 -ac 2 output.mp4 Example for ffv1 using the hstack filter instead of movie+pad+overlay: ffmpeg -i left.avi -i right.avi -filter_complex hstack -c:v ffv1 output.avi. You'll have to use a truly lossless format if you require 'a quality of output video same as input video'. You can add comments to the file, … # videos.txtfile 'input1.mp4'file 'input2.mp4'file 'input3.mp4' $ ffmpeg -f concat -i videos.txt -c copy output8.mp4 $ for f in *.mp4 do echo 'file '$f'' > videos.txt done $ ffmpeg -f concat -i videos.txt -c copy output9.mp4 ffmpeg -i 'concat:input1.mp4|input2.mp4|input3.mp4|input4.mp4' -c copy output10.mp4 FFMPEG Merge two videos into one with side-by-side same quality output

To merge videos using the concat demuxer, first create a text file with a list of videos you want to join. Merge a list of videos with FFmpeg using concat demuxer. Ffmpeg merge multiple sets of 2 videos in for loop.
