Reactor LongLive-2.0
LongLive-2.0 is Reactor's autoregressive real-time video model built for multi-shot generation — a single session moves through many scenes without ever tearing down the stream. Set an opening shot, then steer with soft shot transitions and hard cuts, live or scheduled in advance. Each scene runs up to ~58 seconds (48 chunks of ~1.2s); cutting to a new scene resets the budget, so a session that keeps cutting can run indefinitely.
Overview
| Status | Live in Roamscape |
|---|---|
| Access | API available |
| Released | 2026 |
| Inputs | text prompt (no reference image) |
| Outputs | real-time multi-shot video stream (1280×704 @ 24 fps) |
| Best for | multi-shot real-time sequences, storyboarded scene transitions, long-form generated video, live-directed cinematics |
Why it matters
It reframes real-time generation as directed cinema rather than one endless clip — storyboard scheduling and clean scene cuts make it a tool for narrative sequences, not just ambience.
Roamscape use
Tracked via the Reactor API — a candidate for a future Roamscape multi-shot / cinematic mode.
Strengths
- one continuous session across many scenes
- soft shots keep continuity; hard cuts break to a new scene
- storyboard scheduling at exact chunk indices
- unbounded length via scene cuts
Limitations
- text-only — no reference-image anchoring
- ~58s per scene before a cut is needed to continue
- live stream rather than an exportable asset
- not yet runnable inside Roamscape (Reactor API only)
