A person, not just a face
A reference can guide face, hair and clothing together. Supply the intended wardrobe when it matters; a close-up headshot cannot define every unseen detail.

02
Motion starts with your take
Gestures, blocking and the camera come from the source video. Choose a performance worth keeping rather than asking the replacement to repair a weak shot.
03
Keep people identifiable
Use a clear photo for each person and put them in mapping order. For a two-person shot, describe each source person by location or clothing in the optional instruction.

Where character replacement earns its place
Casting directions
Compare a different character appearance while keeping the take for a storyboard or pitch.
Brand character variants
Try an approved person or mascot reference in footage you own, then review clothing and scene fit.
Short narrative scenes
Keep a compact action beat while trying a new cast. Inspect continuity at every cut.
Social video concepts
Adapt a short, rights-cleared performance without rebuilding the shot from a text prompt.
Prepare a source Recast can follow
The source defines the performance. The photos define the new cast. Give each input one clear job.
Video
A 5–15 second MP4 with a visible subject, readable motion and the framing you want to keep.
Photos
Clear, well-lit portraits with useful hair, angle and wardrobe information; one per replacement person.
Mapping
Match photo order to people from left to right. Explain ambiguous positions with concise instructions.
Know what stays, and what needs review
Source audio
Recast retains the source soundtrack. The new-looking person can still have the original voice.
Wardrobe and small objects
Clothing, fingers, glasses and nearby props may shift. Inspect these details rather than assuming a face-only edit.
Occlusion and crowded frames
People crossing, tiny faces and long occlusions can complicate identity. Start with a clear, short shot.
A different creative task
For a new scene, voice replacement or a background redesign, choose a workflow designed for that task.
A quick check before downloading
- Does the replacement match the intended photo throughout?
- Are the gesture, camera and cut timing still useful?
- Do clothing, hands, glasses and nearby props look coherent?
- Does the retained source sound fit the new cast?
