Your protagonist looks like your protagonist. In every scene.
A persistent memory graph holds your characters, wardrobe, locations, props, and mood across the entire timeline — from scene 1 to the final shot.
Character drift is the reason AI-generated narrative films fall apart. Every clip-first tool generates each shot without memory of the last — so your lead looks different every time the camera cuts. Induce builds a memory graph that never forgets.
Character drift happens when AI generation treats every shot as a blank slate. Induce solves this at the architecture level: a persistent graph that every shot generation reads from.
Five categories. One source of truth.
Every entity in your film lives in the graph from the first time it appears in the script.
Characters — face, build, and state
Every named character gets a persistent node: physical description, distinctive features, and narrative state at any given point in the timeline.
Wardrobe — outfit per scene, transitions tracked
Characters are dressed correctly for the scene they're in, not the first scene they appeared in.
Locations — environment, time, and condition
The precinct in scene 3 is the same precinct in scene 28 — same layout, same light quality.
Props — objects that carry narrative weight
The envelope handed over in scene 4 appears in the same character's hand in scene 12.
Mood — tone and colour across the cut
Scene-level emotional register is tracked as a mood parameter and applied consistently to all shots within that scene.
Change once. Update everywhere.
Change a detail, re-generate everything.
Every shot referencing a character was generated independently. Changing appearance means regenerating each shot manually.
Change a detail, the graph propagates it.
Update a character node and the graph marks all downstream shots as stale. Induce queues targeted re-generation of only the affected shots.
The wardrobe change in act two actually happens.
Narrative state changes are read from the script and applied as temporal events in the graph.
Rewrite page one. The cut reflects it.
Upload a revised screenplay and Induce diffs the two versions. Only changed scenes are re-broken-down.
Continuity in Induce is not a feature you turn on. It is the default state of every project from the moment you upload a script.

Continuity engine questions answered.
What is character drift in AI video?
Character drift is when an AI-generated character looks different from scene to scene — different face shape, different hair, different build — despite representing the same character. It happens because most AI video models generate each clip independently with no shared memory of what came before. The character 'drifts' away from the original reference over multiple generations. It is the most frequently cited problem with AI video for narrative production, and the reason most AI-generated films look incoherent across cuts.
How does Induce keep characters consistent across scenes?
Induce builds a persistent memory graph from the script at ingestion time. Every character, location, wardrobe detail, prop, and scene-level mood registers as a node in this graph. Every shot generation request reads from the graph before rendering. When a character's appearance changes — a new costume, an injury, an aging detail — that change is recorded as a graph update and all downstream shots inherit it automatically. You do not re-upload reference images or re-specify characters scene by scene.
How is Induce's continuity different from LTX Studio's Elements system?
LTX Studio's Elements system requires you to manually configure and upload reference assets for each character, location, and object you want to keep consistent. It is an opt-in, per-asset setup. Induce's continuity graph is automatic and whole-script: it is built from your screenplay at ingestion, requires no manual reference uploads, and covers every character and location that appears in the script. The difference is the default: Induce is consistent by default; LTX Studio is consistent when configured.
Can Induce maintain continuity for wardrobe changes and injuries across scenes?
Yes. Induce tracks narrative state changes — wardrobe transitions, physical injuries, makeup and aging — as temporal events in the memory graph. When a character changes costume on page 32, shots from page 33 onward reflect the new wardrobe. When a character is injured in scene 14, shots in scenes 15 through the end show the injury. These transitions are read from the script's action lines and applied as graph updates, not as separate reference uploads.
Continuity holds your film together. Shot control lets you shape each frame.
Override any shot — angle, lens, lighting, blocking, performance — without breaking the continuity of the scenes around it.
Characters that hold.
Cuts that cohere.
Upload a screenplay and watch your characters remain consistent from scene 1 to the end — without a single reference upload or manual setup.
