Studio · the product

An editor where every clip is a prompt.

Studio looks like the NLE your editor already knows — tracks, a playhead, a properties panel. The difference: select a clip, change a word, and the shot re-renders in place. Picture lock stops being a cliff.

02 Under the hood

One prompt, five passes.

Each pass is a separate model with a separate job. That is why a note like “same shot, less wind” is a 20-second re-render and not a re-roll of the dice.

03 Consistent characters

Cast once. Shoot forever.

Upload one photo — or generate a face from a description — and Kinema Faces builds a character sheet: identity, age, wardrobe, the way they hold their shoulders. Lock what should never change. Leave the rest to the scene.

  • 98.1% identity match across 200-shot sequences on the Kinema Faces benchmark.
  • Wardrobe and prop locks — the coat stays camel, the bottle stays the same bottle.
  • Consent-gated — real faces need a signed release in the project before they can be locked.

04 Camera control

Twelve moves. Real parameters.

Camera moves in Kinema are solved paths, not adjectives. A dolly has a speed in metres per second, an orbit has degrees, a rack focus has two planes and a duration. Preview the path on a top-down map before you render.

  • Dolly, truck, pedestal, pan, tilt, orbit, crane, zoom, rack focus, handheld, whip, lock-off.
  • Lens 24–135 mm, with real perspective change and matched depth of field.
  • Combine two moves — crane up while orbiting, dolly in while racking focus.

05 4K upscaling

Render fast. Finish sharp.

Work at 1080p while you are still deciding. When the cut is locked, run the 4K pass: a dedicated model that rebuilds texture — fabric weave, skin, rain — instead of just sharpening edges. Drag the handle.

  • 3840×2160 or 3840×1600 (2.39:1), 48 or 60 fps.
  • +40 seconds per 8-second shot. Costs 2× credits only on the shots you keep.
  • Temporal-aware — no shimmer between frames, no flicker in gradients.

06 Timeline

Cut like an editor. Re-shoot like a director.

Trim, ripple, reorder. Add titles and a scratch track. Then select a clip and type a note — Studio re-renders only that clip, keeps its length and in-point, and stacks the old take in Versions so nothing is lost.

  • Versions per clip — compare takes side by side, promote the winner.
  • Export the project as Premiere / Resolve XML with media attached.
  • Shared review links with frame-accurate comments.

07 API

Everything in Studio is a parameter.

The REST API mirrors the properties panel one-to-one. Submit a shot, subscribe to a webhook, pull ProRes when it lands. SDKs for Python and TypeScript.

Webhook events

Every pass emits an event, so a pipeline can start conforming while the upscaler is still running.
