Recasting Explained: Keep the Take, Change the Faces

Nothing gets re-shot. The footage you already have supplies the acting and the runtime, while the portraits you upload decide whose face appears on screen.

  • Up to Four New Faces, Mapped Left to Right
    Give one clear portrait per person, four at most. They replace the main on-screen figures from left to right in every shot those people appear in, so the photo order must follow the positions in frame.
  • Original Acting and Camera Stay Intact
    The clip does the performing — gestures, beats, facial expressions, scene lighting and the way the lens travels are all preserved. Only faces change, along with wardrobe when your photo shows it.
  • Low-Cost 768p Preview Before the 1080p Render
    A quick low-resolution pass confirms casting and identity before you commit to a 1080p final, and pricing follows clip length rather than a flat fee.

How Face Swap MiniMax H3 Works

Three steps — bring in the footage, arrange the portraits, then preview and render. The finished length and the soundtrack carry over.

Where Face Swap MiniMax H3 Shines

It behaves like a casting desk for material that is already shot. You are not generating a fresh clip — you are deciding who appears inside the one you have.

Prompt Override for Cast Mapping

A brief optional prompt beats the default left-to-right assignment — for instance, you can state that the woman on the right should become person 1.

Identity Tracked Across Cuts

Swapped faces hold through the edit, because each person's identity is followed across cut points in every shot they appear in.

Cut Rhythm and Audio Left Alone

Original edit points and the soundtrack pass through untouched, so a recast slots into the finished clip rather than rebuilding it from scratch.

Output Length Matches the Source

The finished piece runs exactly as long as the source, so nothing needs re-timing or re-editing, and the price scales with duration.

What Makes a Good Reference Photo

One sharp, front-facing, evenly lit photo per person; a half-body frame carries hair and clothing better than a tight headshot, while sunglasses, hats, covered faces, group shots and heavily filtered portraits weaken the result.

Known Limits: Crowds, Small Faces, Fast Action

Busy crowds, distant or tiny faces, rapid action and occlusion after hard cuts are weak spots, and identity can drift back toward the original actor in long shots or profile turns.

FAQ

Face Swap MiniMax H3: Frequently Asked Questions

Answers to the questions people ask most about swapping the cast in footage they already have.

1

What exactly does this tool do?

It replaces the people in footage you already have: your portraits take the place of the on-screen cast, while motion, camera behaviour, edit points and audio stay as recorded. Nothing is generated from scratch.

2

How long can the source clip be?

Anything from five to thirty seconds. Each individual shot must stay under fifteen seconds, so split longer takes before uploading; the result comes back the same length as the input.

3

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

Four at most, with a single photo each. The default reading is left to right, matching the main figures on screen; a brief prompt lets you reassign them if that order is wrong.

4

Which reference photos work best?

A crisp, well-lit portrait facing the camera, framed around the torso rather than the head alone so hair and clothes are visible. Avoid shades, headwear, a hand across the face, several people in one frame, heavy filters or low resolution.

5

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

Run the low-resolution pass first to check the right face landed on the right person, then output at full 1080p. Pricing tracks runtime, so a wrong photo caught early costs very little.

6

When is this the wrong tool?

Skip it if you want brand-new movement, different camera angles or another location — the uploaded clip decides those. It also struggles with packed scenes, tiny or distant faces, and rapid motion or objects crossing the face right after a cut.
