Option to letterbox (instead of crop) when concatenating videos with different ratios

[luckydesigner123]

I want to merge 2 with with different ratio on in landscape and one in potrait but when i merge both videos is in portrait.

I need both videos in diffrent ration and orientation how to do that

I too have this problem. Can someone help how to deal with this or just point out the part of the code ( sorry I am an absolute beginer ) that does the aspect ratio stuff ( may be I can study it and modify it) .

(Pasted to all my answers today: it's been a long time since my last issues review. I am sorry about the delay and I know you likely have moved on by now. Still, I'm going to answer where I can)

This is not possible currently, but it's a good feature request.
