So I'm trying to do a simple thing: I've got this video shot, where camera zooms out of the scene, and I want to undo that zoom so that the scene stays the same scale.
I tried using the Perspective Corner Pin thingy, but no matter which points I choose, the analysis is damn wonky. It scales and twists the entire image, instead of making it stable. Plus, only if I select stabilise the "Apply" button un-greys out. So, what do I do wrong?
