Frequently asked questions
Will this automatically reframe the subject?
No. It changes the output canvas and fits the original video. Automated subject-aware reframing is a different workflow.
Why use fit-and-pad?
It avoids accidentally cutting off faces, products or visual details that may sit near the edge of an AI-generated frame.
