Asymetric mask adjustment

[Mike2003]

I would like to add a mask to an image but would like to pull each corner of the mask into a point on the image which whilst rectangular is asymmetric. Can this be done? I have looked in the help file and the forum, maybe I have searched using the wrong term. Any suggestions would be helpful. I want to map a video image onto a building where the building is asymmetrical partly because I have used a wide angle lens.

Hi Mike,

You need to use the 3D rotation to adjust it.

I have used 3D movements X, Y & Z to correct converging verticals.
It may not be as accurate as doing it in something like Photoshop, but with some trial & error you can get it near enough.

Hi Jill, thanks for reply, that's what  have been doing and have been tearing my hair out, its very much trial and error as you say and its still not quite right.    I was wondering if   had missed a more elegant and user friendly option.
