The bitGen Studio window: references on the left, the preview in the middle, the prompt below it and the gallery on the right — The whole studio in one window. Every panel is a docker you can float, dock or tuck away.

One studio for the whole film

From one sentence to a whole film

A local language model writes the screenplay. The StoryBoard turns each scene into a shot, and the characters keep their faces and their own cloned voices from scene to scene.

Films with dialogue, or music videos cut to the beats of a song
MiniMax H3, LTX and Wan video models through ComfyUI
Character swap, lip sync, VR footage and SeedVR2 upscaling

A StoryBoard of scenes, each with its picture, prompt and shot

Cut it on a real timeline

Layers, keyframes, effects and adjustment layers on a preview canvas, with the tools you expect from an editor.

Colour grading, masks and tracking, multicam and nesting
Captions, karaoke with a bouncing ball, transitions and a track mixer
Proxies for big footage; export when it is right

The timeline with its layers and keyframes

Paint, comp and design

An image editor with layers, masks, smart objects and adjustment layers - and the AI in it, for generating, refining and filling.

Selections, painting, retouching, puppet warp and liquify
Type with OpenType features, vector shapes and the pen
CAD sketch layers with real dimensions and a parametric 3D body

Build the set

Sketcher is quick 3D modelling: draw, push and pull, then whole rooms and houses with shared walls, doors, windows, roofs and stairs.

Floor plans, sections and printable sheets
Lights and cameras, then render the room as a shot
Blender, Daz Studio and Unreal Engine links for the heavy lifting

Score it and give it a voice

Songs, stems and sound effects made on your own card, and voices cloned from a few seconds of speech.

Music with MiniMax Music3 and YuE2, and split stems
Text to speech in your characters' voices, speech to text
A sound effects docker that fills a scene with sound

That is the short version. Every feature - 963 of them - is listed with where to find it.
