Why Use H3 Recast
H3 Recast operates on footage that already exists, preserving the performance while altering only the person on screen.
- A Casting Swap, Not a GenerationNothing in the take is regenerated — H3 Recast preserves what the footage gets right and alters only the person on screen.
- As Many as Four Faces, Screen-Left to Screen-RightSupply up to four portraits and they take over the leading figures in each shot those figures show up in, holding the same identity through every edit point.
- Performance, Edits and Audio InheritedEvery glance and gesture, the beat of the acting, the light as it falls and the finished audio mix survive the swap.
How to Use H3 Recast
Three steps take a finished clip to a new cast with H3 Recast.
H3 Recast Features
What H3 Recast carries over, what it swaps, and how to keep the original styling when you need it.
Identity Tracked Across Cuts
A given portrait keeps taking over the same individual in each shot that person turns up in, so the casting holds as the edit moves between cuts.
Prompt Override for Cast Order
The default pairing runs left to right; a brief prompt naming each on-screen figure and its photo changes that assignment.
Face-Only Replacement Prompt
Leave the prompt empty and the portrait's styling can come along too; request the face alone if the wardrobe and hair must stay as captured.
768p Test Before 1080p Final
A quick preview render settles whether the cast reads right before credits go toward the full-resolution finish.
Output Length Matches the Source
Length in equals length out, which ties spend to how long the clip runs rather than to an arbitrary setting.
Edit Rhythm and Sound Carried Over
The edit's pacing and its audio survive untouched, so the new version slots straight into the timeline.
H3 Recast — FAQ
Common questions about recasting the people in a finished clip with H3 Recast.
How long can the source video be?
Five to thirty seconds, with no individual shot past fifteen seconds. Split long takes first; output mirrors input length.
How many people can I recast, and in what order?
Four at most, one portrait each. Leading figures are taken over left to right by default; a prompt can change that pairing.
What kind of reference photos work best?
One sharp, evenly lit, front-facing portrait per person. Skip shades, hats, hidden faces, group shots, blurry files and heavy filters.
Will the photo change hair and clothes too?
Often yes without a prompt, even from a head crop. Ask for the face only if the original hair and wardrobe must stay.
Should I use 768p or 1080p?
Preview at 768p to validate the cast, then finish at 1080p; pricing follows clip length.
When should I not use it?
Not when new movement, camera work or setting is needed. Crowds, tiny faces, fast action and occlusion break it, and likeness can drift in long shots.
