I'm struggling to find the right Frei0r plugin / approach to be able to do a keyframed animated crop and pan across a 1080P frame using a 720P zone for rendering out at 720P. Is this possible?
Seem to have one approach working instead of using a 720P project and trying to find a plugin that lets me place a 720P wireframe over a 1080P video by using the mouse to position it and keyframe that, by using a 1080P and then creating a 720P mask with transparency in Gimp as a guide, composite it over the video strip and use the Pan and Zoom effect to move the video strip up/down/left/right and keyframe that. Then crop at fixed position over the whole video timeline after?
A keyframeable crop would be a lot simpler. :-)
