What H3 Recast Brings to Footage You Already Cut
Rather than generating a brand-new scene, H3 Recast re-casts a take you have already shot, so the acting, framing and sound carry through untouched.
- Re-Casting, Not RegenerationNothing in the take is rebuilt from scratch — the tool keeps what the camera captured and changes only who is standing in frame.
- Up to Four New Faces, Left to RightHand it as many as four portraits and each one claims a lead role in every shot that person appears in, so identity stays consistent across cuts.
- Acting, Cuts and Audio Carry OverGlances, gestures, the timing of the performance, the light falling across the scene and the finished mix all come through the swap intact.
How H3 Recast Works in Three Steps
From an edited clip to a fresh lineup of faces — the whole H3 Recast pass takes three moves.
Inside H3 Recast: What It Keeps and What It Swaps
A closer look at how H3 Recast holds identity across cuts, overrides the default pairing, and protects the look of the original footage.
One Portrait, Every Cut
A portrait keeps claiming the same performer in each shot that person shows up in, so the casting stays stable as the edit jumps between angles.
Reorder the Cast with a Prompt
Pairing defaults to screen-left first; name each on-screen figure and its photo in a short prompt to change who becomes whom.
Keep Hair and Wardrobe If You Want
With no prompt, a portrait's styling can travel along with it; ask for the face alone when the original hair and clothing must survive.
Cheap Preview Before the Final Render
A fast low-resolution pass answers whether the new cast reads right before you spend credits on the full-quality output.
Runtime Stays Exactly as Shot
What goes in comes out at the same length, so cost tracks the duration of your clip rather than an arbitrary setting.
Pacing and Mix Left Untouched
The cut's rhythm and its audio come through unchanged, so the new version drops straight back onto the timeline.
H3 Recast FAQ: Casting, Photos and Limits
Straight answers about re-casting the people in footage you have already finished with H3 Recast.
How Long Can the Source Clip Be?
Between five and thirty seconds, and no single shot beyond fifteen. Split longer takes first; the output matches the input in length.
How Many Faces Can I Swap at Once?
Up to four, one portrait each. Leads are claimed left to right by default, and a prompt can flip that assignment.
Which Photos Give the Cleanest Result?
A single sharp, evenly lit, front-facing portrait per person. Avoid sunglasses, hats, covered faces, group photos, blurry files and heavy filters.
Does the Portrait Also Replace Hair and Clothes?
Frequently yes when no prompt is given, even from a tight head crop. Ask for the face only if the original hair and wardrobe must stay.
768p or 1080p — Which Should I Pick?
Check the casting at 768p first, then finish at 1080p; what you pay follows the length of the clip.
When Is Re-Casting the Wrong Choice?
When you need new movement, new camera work or a new location. Crowds, tiny faces, fast action and occlusion break the swap, and likeness can drift in long shots.
Give Your Finished Clip a New Cast on Fuser
Bring a clip that is already cut and scored, then change only the people in it — H3 Recast holds the timing, camera work, edits and audio right where they were.
