Your prompt
The character performs in exact synchronisation with the driving performance, matching its timing beat for beat across the whole take. Head position, eyeline, jaw movement and the small muscle changes around the eyes and mouth all follow the source, while the character's own face, build, wardrobe and colouring stay locked to the reference and hold steady throughout. The performance reads as {{performance-quality}}, carried through the eyes and the small movements rather than through broad gesture. The camera holds a locked-off medium close-up at eye level for the entire clip, letting the performance do all the work. Light falls consistently from one direction, keeping the modelling on the face stable as the head turns. {{setting}} sits well out of focus behind, reduced to soft tonal shapes. Aspect ratio: {{aspect-ratio}}.

Record your driving performance first: face the camera squarely in even, flat lighting, keep your head within frame throughout, and perform a little more subtly than feels natural, since Act-Two amplifies expression. Attach that clip as the driving video and your character image as the reference. Keep takes short — sync holds best over a few seconds and drifts on longer performances. A locked-off camera is strongly preferred here, because camera movement competes with the transferred performance and makes sync errors far more visible.
