No waitlist · No subscription · Pay per second
What's new in 2.5
A bigger leap than the version number suggests.
Longer single shots
Up to 30 seconds of continuous, single-shot generation — long enough for a full scene, not just a clip.
Up to 50 references
Guide a generation with many more multimodal references, so characters, products and style hold across the shot.
In-video editing
Adjust elements inside a generated shot instead of re-rolling the whole thing from scratch.
Sharper prompt control
Reported improvements in how closely the output follows your prompt — fewer takes to land the shot you described.
Directable to the second
Integer-second timestamps — 0–3s, 3–8s — direct the shot like a script, scene by scene.
Synced audio
Native audio generated in step with the motion — no separate pass to line up sound.
Coming to Studio
The moment it lands, it's one click away.
