Wrong angle, how to fix?

[color]

I got a movie filmed with a vhs-camera but its in an angle (sadly the original movie does not exist anymore so this is the only copy.) I don't realy know what its called when its not "straight".



Also, the camera is changing a bit, is it possible to crop the black automaticly frame per frame?

It needs to go from:

Look to
DavidHorman:- http://horman.net/avisynth/
(maybe Quad)

and

VCMohan plugins:- http://www.avisynth.nl/users/vcmohan/
(maybe one of Perspective, Reform, Reformer).

EDIT: They both have plugs that correct your prob, but not sure of names.

EDIT:
DavidHorman quad dll, using Martin53 demo avs (FlyingColorbars.avs)

I have tried to get it to work properly, but it was not as easy as I thought. Thank you for the links.

I ended up using:

defish(fov=50, scaling="fitx")
Perspective(a= -0.0001, b = 0.00005, ea = 0.0005, eb = -0.0005, x=505,y=655,z =5, color =$00)

It does leave a black line on the top, but thankfully its not so mutch so it can be croped away.
