What H3 Recast Does to Footage You Have Already Shot

It starts from a clip you have already finished, leaving the performance and the edit alone while changing who appears on screen.

  • Swaps the Cast Without Regenerating the Scene
    Nothing in the take gets rebuilt. H3 Recast keeps everything the footage already does well and changes only the person in frame.
  • Up to Four New Faces, Matched Left to Right
    Hand over as many as four portraits and each one takes over a leading figure, holding that identity across every shot the person turns up in.
  • Acting, Cuts and Audio Come Through Intact
    Every glance and gesture, the rhythm of the performance, the way light falls and the finished mix all survive the swap unchanged.

Running H3 Recast in Three Steps

With H3 Recast, three quick moves take a finished clip to a brand-new cast.

H3 Recast Capabilities at a Glance

See what H3 Recast carries over, what it replaces, and how to hold on to the original styling when that matters.

One Portrait, Consistent Through Every Cut

Each portrait keeps taking over the same individual wherever that person appears, so the new cast stays coherent as the edit jumps between shots.

Rewrite the Pairing with a Short Prompt

Faces are assigned left to right by default; naming each on-screen figure alongside its photo in the prompt overrides that order.

Keep Hair and Wardrobe with a Face-Only Swap

An empty prompt may let the portrait's styling carry over; ask for the face alone when the original hair and clothing must stay as captured.

Low-Cost Preview Before the Final Render

A quick 768p pass shows whether the new cast reads correctly before any credits go toward the full-resolution finish.

Runtime Mirrors the Source Clip

What goes in comes out at the same length, so cost tracks the duration of your clip rather than an arbitrary setting.

Pacing and Audio Left Untouched

The cut's rhythm and its audio mix survive exactly as they were, so the recast version drops straight back into your timeline.

FAQ

H3 Recast: Questions People Ask

Straight answers to the questions that come up most often when recasting the people in footage you have already shot.

1

How long a clip can I recast?

Between five and thirty seconds, and no single shot longer than fifteen. Split longer takes first; the output matches the input in length.

2

How many people can I swap, and in what order?

Up to four, one portrait each. Leading figures are replaced left to right by default, and a prompt can change that pairing.

3

Which reference photos give the best results?

A single sharp, evenly lit, front-facing portrait per person. Avoid sunglasses, hats, covered faces, group photos, blurry files and heavy filters.

4

Will my photo also change hair and clothing?

Often it will when no prompt is given, even from a head-and-shoulders crop. Ask for a face-only swap if the original hair and wardrobe must remain.

5

Should I preview at 768p or go straight to 1080p?

Validate the cast at 768p first, then finish at 1080p — pricing scales with clip length.

6

When is H3 Recast the wrong tool?

When the shot needs new movement, a new camera move or a new location. Crowds, very small faces, fast action and heavy occlusion break the swap, and likeness can drift across long takes.
