I have hundreds of videos I've taken on my iPhone over the years that I would like to combine/merge into one long video. Some of these videos were taken in portrait mode, some in landscape mode. I'd like the end result to be just one long combined video - I'm aware that there will need to be blurry/black bars on the sides of portrait videos and the top and bottom of landscape videos if they're combined together, and I'm fine with that.

I've spent months trying out different ways to do this efficiently but have not found a solution. I know there are tons of programs that will combine videos, but I haven't found one that will (i) rotate portrait-mode videos, (ii) add black bars where necessary so that all videos when combined have the same height/width, and finally (iii) combine them.

I'm on Windows but have access to a Mac. I'm even willing to pay a fair amount for the right program, I just want to know that it will work for my purposes.

Thank you to anyone who can help, it means a lot.
