I need to overlap one video on top of another one using AlphaOver. I have done this before. The tricky part this time around is that the one that I’m AlphaOvering, is shorter than it’s background counterpart (the other video).
My question is: How do I position the small one in a precise place in respect of the large one (the background)? Let’s say, to make it start at frame number 400 (which is half way the length of the large one).
I hope I was clear enough.
Thanks in advance guys,
