How to stretch an image in vegas? Tips? (Reference image in body) That's as far as I had gone, I am trying to fit the image in the box but I just can't figure it out. no matter how much I stretch it or rotate it,  it just doesn't work

Here's another image so you guys know my pan/crop settings


and if you need to try it yourself, here's a green screen. if you at least get a still frame I guess I can animate it from there (Though, actually tell me how did you get it to work)



I also wonder, if I already have the mask, and it's already animated and stuff, could that help me?

Edit:Wait, do you guys need a green screen lol? I am going to leave it there just in case but I don't think you guys need it (Note:The green screen was made by me, by using the mask. I got the mask with the keyframes, I really hope that's useful)
I believe most of this effect can be achieved using Deform FX. 

For true perspective, you need 3D track motion. 

I have not used either but here are some links:
