I was intend to do my project in 720 resolution. For unknown reason, it was created in 1080. Without knowing it, I spent days working with "Position and Zoom" frame by frame. When I rendered it I noticed that's wrong. Now when I change it to 720 of course all positions are wrong
What can I do?
Can I leave the project as 1080, but render the output video in 720?

Just found the "Rescale" in the Rendering popup. It seems now working
