merge and concat video using ffmpeg
I have 2 videos both same resolution left.mp4
and right.mp4
(1280*720).
Following are the transformations that I need to do:
Stack these 2 both videos side-by-side, this results in a wide video with top and bottom padding.
ffmpeg -i left.mp4 -i right.mp4 -filter_complex "[0:v][1:v]hstack=inputs=2,scale=1280:720" merged.mp4
Next concat
left.mp4
andmerged.mp4
:
ffmpeg -i left.mp4 -i merged.mp4 -filter_complex "[v0][0:a][v1][1:a]concat=n=2:v=1:a=1[v][a]" -map [v] -map [a] concat.mp4
Resulting concat.mp4
has both videos, but merged.mp4
content is stretched instead of top and bottom padding. I want left.mp4
and merged.mp4
to have their own resolution with padding.
Not sure what I miss here.
