Screen Replacement/Color Correction Question

Hello,
Teaching myself Fusion today and using screen replacement as the project. I've been able to replace the screen with a pic using the planar tracker, key out the green, and merge a background behind the pic to clean things up. I would like to use a color corrector on the mediain2 node, make it look a bit more like it's supposed to be there. When I add the corrector, it doesn't stay within the confines of the corner pins. I've tried adding polygon's and another tracker pre correction, but I just can't sort it out. Any advice? Is there an easier way? Pics below.

Complete newb here, go easy. Thanks all.

Not sure if this is the problem as I can't see the images but try going to the 'options' tab on the color corrector and selecting the Pre-Divide / Post Multiply option.

Hi,

the images you posted are not visible.

Since it's the OP's first post on the forum, he can't post images yet.

Thanks all. Sorted it out. Instead of dropping media directly into Fusion, I did the create fusion clip. Was able make adjustments much easier.

Awesome forum. Thanks all.
