ValueErrorin LTXDirector (node 131)

Number of segment_lengths (1) must match number of local prompts (3). This almost always means a '|' character appears INSIDE one of your timeline segment prompts: the Director uses '|' to separate segments, so a '|' in the prompt text splits it into extra phantom segments. Remove every '|' from your segment prompts (use a comma or dash instead) and re-run.

[SHOT 1.05 | START FRAME: NB 1.05 still | DURATION: 8s] A tired woman having a cigarette outside a crime scene, thinking. She draws slow on the cigarette. Holds it a beat. Exhales — a long thin trail of smoke drifting sideways across the light. A second draw a little later, smaller. Small, real, unhurried. The performance is in her eyes and her face — real, subtle, unforced. Her eyes flicker faintly as thoughts move behind them, focused somewhere off-lens; one slow heavy blink; a barely-there tightening at the outer eyes — the exhaustion of someone who has seen too much and slept badly for years. The corner of her mouth pulls the smallest fraction as she exhales — not a smile, just a life. Her nostrils flare once softly on a breath. A single strand of hair moves by her temple. She does not speak. She does not react. She thinks. She feels. Camera locked. She stays where she is. Real-time. Backlit smoke catching the light. Cold morning around a warm face.
