Casting Director

Casting is deciding who looks and feels right for each role — and maintaining that person's consistency across every scene in the film. In ACT3 AI, you create digital actors, define their appearance and personality, and cast them into the script. Once cast, the AI keeps them visually consistent across every shot they appear in.


Your work in ACT3 AI

Digital actors are reusable assets. You build them once and they can appear in any scene, any project. Their look, voice, and motion capture data all travel with them.


What you'll do here

Tasks are listed most common first.

Create a new digital actor

Build a character from scratch using text description, reference photos, or a combination. Define their appearance, age, physical build, and default wardrobe.

How to create a digital actor

Cast an actor into a scene

Assign a digital actor to a character name in the script. From that point on, every shot that references that character uses that actor.

Manage your cast list

View all actors across a project, see which scenes they appear in, and make bulk updates across all their appearances from one place.

Adjust an actor's appearance for a scene

Characters change over time — aging, wardrobe changes, injuries. You can define per-scene appearance overrides for an actor without changing their base definition.

How to modify actor appearance per scene

Add motion capture to an actor

Bring performance data from iPhone motion capture or uploaded mocap files into an actor. The motion drives body movement and facial animation in the rendered shot.

Maintain visual consistency across scenes

Review continuity — same hair, costume, and physical characteristics across every shot. The character panel shows consistency status and flags differences.

How to check actor consistency

Create an ensemble or crowd

For scenes needing background actors or large groups, create generalized "extra" characters with varied appearances and place them in bulk in the top-down editor.
