Frequently asked questions
Does this crop to 9:16?
No. The default behavior fits the complete source frame and pads unused space. This is safer for AI-generated subjects near the edge of frame.
Can I use it for AI-generated clips?
Yes. It is useful when a generated shot was created in landscape but needs a vertical review or social version.
