Where H3 Recast Fits in Your Workflow
It works on video that is already in the can: the acting, pacing and audio survive intact, and only the on-screen identity changes.
- A Swap, Not a RegenerationNothing is re-imagined from scratch. The take you shot stays exactly as it is; the only thing that changes is who appears inside it.
- Up to Four New Faces, Mapped Left to RightEach portrait claims one of the leading figures and keeps that role in every shot the person turns up in, so the casting never drifts between cuts.
- Acting, Cuts and Sound Carry ThroughEvery glance and gesture, the rhythm of the performance, the light falling across the scene and the finished mix all come out of the swap unchanged.
Running H3 Recast in Three Steps
Load a clip, attach portraits, preview the result — that is the entire process.
Inside H3 Recast: What It Keeps and What It Changes
A closer look at what survives the swap, what gets replaced, and how to hold on to the original styling when it matters.
One Face, Every Cut
A portrait keeps claiming the same individual in each shot that person shows up in, so the casting stays consistent as the edit jumps between angles.
Reorder the Cast With a Prompt
Pairings default to left-to-right; name each on-screen figure and its photo in a brief prompt to change who plays whom.
Face-Only Swap on Request
With no prompt, the portrait's styling may come along for the ride; ask for the face alone when hair and wardrobe must stay exactly as captured.
Cheap Preview, Full-Res Finish
A quick 768p render tells you whether the cast reads right before you spend credits on the 1080p master.
Runtime Stays Identical
What goes in comes out at the same length, so cost tracks the clip's duration rather than an arbitrary setting.
Pacing and Audio Untouched
The cut's rhythm and its sound mix come through unchanged, so the new version drops straight back onto your timeline.
H3 Recast: Your Questions, Answered
Everything people ask before they recast a finished clip with H3 Recast.
What is the maximum clip length?
Five to thirty seconds, and no single shot longer than fifteen. Cut longer takes first — the output runs the same length as the input.
How many faces can I swap at once?
Four, with one portrait apiece. Leading figures are claimed left to right by default; a prompt can reassign them.
Which reference photos give the best results?
A sharp, evenly lit, front-facing portrait per person. Avoid sunglasses, hats, covered faces, group shots, blurry images and heavy filters.
Does the portrait also change hair and wardrobe?
Frequently yes, even from a headshot crop. If the original hair and clothing have to stay, request a face-only swap.
Do I need to render at 1080p?
Preview in 768p to check the casting, then finish in 1080p. Pricing scales with clip length either way.
When is this the wrong tool?
Whenever you need new movement, a new camera angle or a different location. Crowds, very small faces, fast action and heavy occlusion all break the swap, and likeness can drift over long shots.
Put H3 Recast to Work on Your Next Clip
Bring a clip that is already edited and mixed, then swap the people in it and nothing else. Timing, camera work, cuts and audio all stay exactly where they were.
