Reference & editing workflows

AI Video Background Replacement Guide

A believable background replacement must match perspective, scale, lighting and parallax. The foreground should not be regenerated unnecessarily.

Foreground lock

Identity, wardrobe, pose timing and silhouette.

Perspective

New background horizon and camera height should match the shot.

Lighting

Adapt contact shadows and bounce light.

Parallax

Background movement must remain consistent with the original camera motion.

A practical reference workflow

  1. Identify the exact role of every reference: identity, product, environment, motion, start frame, end frame or edit target.
  2. Write down the elements that must remain unchanged before describing motion or edits.
  3. Describe one primary change at a time: action, camera, lighting, background, style or continuation.
  4. End with a stable target state that can be reviewed, edited or used as the next clip reference.
