Video Assembly Motion X

Sets the horizontal focal point for Ken Burns motion on an image segment, overriding the default center.

video-assembly-motion-x[N] accepts a float from 0 to 1, where 0 is the left edge and 1 is the right edge. The default is 0.5 (center).

Use this with video-assembly-motion-y[N] to push the zoom toward a specific subject — for example, a fireplace on the right side of a room photo.

Applies to image segments only — ignored on video segments.
