As a side note, I also did a removal of a car driving on a road next to this dealership. It looks awesome and only took 10 minutes.
OK so I have a simple shot. A drone mostly hovering, but slightly moving toward a car dealer. There is a car parked on the lot I’m removing. Since this car doesn’t move, I figured cleanplate is the way to go. Create cleanplate, edit in Photoshop, done. I track the car making sure to encompass everything. Then I track the background, using a spline large enough to cover the car layer, with the car layer on top. Perfect. I then go to the Remove tab, select the car layer and import the cleanplate. Hit Render Frame. Bam. Flawless.
Problem comes in when I try to render the rest of the frames. The car layer moves with the motion, but the cleanplate image stays where it was on the frame I created it from. Am I missing something?
