Topic: Superposition manual alignment
is it possible to align two superpositioned videos manually? I found that I can drag a video in one screen and it's overlay would move in the other as well. But it's hard to get it accurate that way. I would also need to zoom and transform.
In my case, the static background is a plane surface of known size. So, ideally, I would draw two perspective grids (one per video) and use that information to compute the (affine) transformation from one video "plane" to the other. Applying the transformation would give us a nice aligned superposition.
Is that perhaps already possible and I haven't seen it?
