Good afternoon, did anyone make a video merging horizontally?
Maybe he just has an idea how to do it?
Preferably with the help of ffmpeg
in other words: there are two videos 640x480 lasting 5 minutes each
after gluing it turns out a video 1280x480 also lasting 5 minutes
thanks in advance

ffmpeg, overlay filter , see its examples right for your case:

ffmpeg -i left.avi -i right.avi -filter_complex "
nullsrc=size=200x100 [background];
[0:v] setpts=PTS-STARTPTS, scale=100x100 [left];
[1:v] setpts=PTS-STARTPTS, scale=100x100 [right];
[background][left]       overlay=shortest=1       [background+left];
[background+left][right] overlay=shortest=1:x=100 [left+right]
"  output.mp4

Only here they are adjusted to the size of 100x100 each, and you have other sizes - adjust.
