MinimaxHailuo03MaxReframeVideoNode - ComfyUI Built-in Node Documentation - ComfyUI

This node adapts a video to a new aspect ratio by fitting it on a new canvas and generating the surrounding areas. The timing and sound of the source video are kept. Use it to turn a landscape clip into a vertical one, or the other way around, without cropping the subject out of frame.
