I've created some time-lapse videos from photos, using this command:
ffmpeg -i IMG_%03d.JPG -s 1440x1080 -sameq video.MP4
And it worked great. Now I want to join several of these time-lapse videos to make a single, longer video (all the input videos have the exactly same format). I already tried using:
cat video1.MP4 video2.MP4 > stitch.MP4
but the output ends up being equal to video1.MP4
I don't want to transcode nor changing any parameter of the video, I just want a end-to-end stitching, as if those videos were on a playlist.
