Morphing

Narrative function

A face becomes another face while the eyes stay aligned. A body interpolates toward a new contour.

Use it when becoming should be visible as a correspondence of landmarks, not as a cut or a fade. It is the wrong tool when the person stays the same and the room should change, or when makeup and performance can do the work in stages.

If only opacity changes, you shot a dissolve.

How it works

Lock pose, eyeline, and key on two endpoints. Set landmark matches (eyes to eyes, mouth to mouth, silhouette to silhouette).

Separate foreground from background so the warp does not drag the room. Control which features change first.

The midpoint should be an intentional in-between, not a melt. Prompt a morph of the subject into another state: continuous transformation, identity as a dissolve you can watch.

For video, morph into another form over the shot.

When to use it

Use it for the beat when one form must become another in a few seconds of continuous view. Do not use it as a fancy cut between two unrelated shots with no shared landmarks.

Compared with similar shots

Morph as an edit uses the warp as the join between two shots. Morphing here is the geometric interpolation itself.

Transformation can be practical makeup, a set change, or a world swap around a stable body. Morphing is landmark geometry, not a new room.

In film

Terminator 2 interpolates chrome and flesh as correspondence. Michael Jackson's Black or White walks faces through aligned landmarks.

Willow interpolates between creature forms. Grammar, not frames to copy.

• Willow 1988Transformation passages visibly interpolate between forms.

Prompt it

Morph of [Subject] into another state, continuous transformation, identity as a dissolve you can watch. Video: [Subject] morphs into another form over the shot.

Name both endpoints, keep eyes aligned, and forbid a cross-dissolve of unmatched poses.

Transform a close-up of a young fictional woman’s face into her older self over four seconds. Keep eyes aligned, head pose, expression and light direction fixed. Age changes occur gradually and coherently. Use matched endpoint portraits and controlled landmark-based compositing, no identity swap or liquefying face.

What usually goes wrong

The usual wrong cousin is a Dissolve. The tell is two images fading with no shared contour, or a liquefying face with no midpoint design.

The fix is matched pose, matched light, and landmarks that travel.
