One Take, Two Faces
Reference Acting to AI Generation
One actor's take, one voice recording, and a different face on screen — the same performance re-cast after the shoot rather than before it.

Mission Brief
The objective, and how we met it.
// The Challenge
Casting is decided before a frame is shot, and it is the most expensive decision to reverse. The question was whether a performance could be captured once and cast afterwards — with the timing, the delivery and the voice all preserved well enough to survive a side-by-side comparison rather than a flattering edit.
// What We Deployed
The character is built before any performance touches it. A reference portrait fixes the face, the wardrobe and the light; a turnaround sheet then locks that same character across front, three-quarter, profile and back, so every later frame has something to be consistent with. Only then does the performance arrive: a single take of an actor delivering to camera, whose timing, beats, head turns and closing gesture are transferred onto the built character and lip-synced to the original voice recording. Nothing is re-shot, nothing is re-read, and no motion-capture rig is involved. The output holds frame-for-frame against the reference across the full take, which is the part that actually decides whether a shot is usable: drift of even a fifth of a second reads as wrong long before a viewer can say why.
// BUILD
Before the performance
The character is made first.
A generated face drifts the moment the head turns unless there is something for it to be consistent with. These two plates are that something.
01 · Character portrait
Generated first. Fixes the face, the wardrobe and the key light — everything the performance will later be hung on.
02 · Character sheet
The same character turned through front, three-quarter, profile and back, with head detail. This is what a generated face is checked against when it moves.

Engagement Log
How the mission ran.
Every PAR2 engagement runs the same four-phase doctrine — adapted here to the specifics of this operation.
01
Recon

02
Strategy
Set the operating plan and success criteria, aligning ai film pipeline & performance transfer & post production into a single line of attack.
03
Build
Engineered and iterated in the field — single reference take transferred to a different character, validated continuously.
04
Deploy
Shipped, monitored, and tuned. One Take, Two Faces stands as the headline outcome of the deployment.

Both plates above were generated on Higgsfield before any performance was applied.
This case study documents a technique. Both performances are shown to explain how the work was made — not to suggest that either performer endorses, is associated with, or has any connection to PAR2 LABS or anything we sell. Neither likeness is licensed, sold, or offered for use by anyone else, and the film is not an advertisement for any person or product. All rights in the original performance and in the depicted likeness remain with their owners. If you hold either and want this taken down, write to ceo@par2labs.com and we will remove it.
