Multi-scene videos

Give each substantial scene its own component and connect it when it benefits from an independent editing timeline. Keep each instance's name, timing, and props inline in the parent.

Choose the parent structure from the editing behavior:

• For independent scene start times, use a named Track with explicit from and durationInFrames on each scene. Its items must not overlap.
• For scenes that should remain adjacent as their durations change, use TransitionSeries. Keep each scene inside its own TransitionSeries.Sequence, with duration and source trim on that boundary. Add transitions when needed and account for their overlaps in the total composition duration.

Follow editable timeline structure (timeline-structure.md in the remotion-interactivity skill) for a complete scene, parent, and registration example. See transitions [blocked] for transition timing and presentations, and connected compositions [blocked] for extraction and verification in the full video.
