Keystone correction?

[RoadRanger]

Is there a filter for keystone correction or does anyone know of another product I could pre-process my clips though for keystone correction? Thanks!

Can't think of a filter which will do it automatically - but if you put your videos in the overlay track instead of the top track you have the ability to distort the image manually and could get your uprights vertical again by just moving corners individually - moving the GREEN boxes at the corners then either apply the crop filter to cut the edges of the images vertical as well or just stretch the distorted image (using yellow boxes) until the edges are off screen.

That sounds promising - I'm actually trying to partially correct keystoneing in the other direction. I will often have to shoot a band from one side and want to stretch the performers on the far side of the stage to more match the apparent height of those on the near side. Now that I think of it this will "fix" the height but not the width - dunno if there is anyway to do a non-linear stretch - kinda a "funhouse mirror" effect?

The green blocks allow distortion in any direction so you should be able to move up and out at the same time

You can actually distort in the main track - select the clip, pull up options on the left center, select attribute, click Distort Clip.
