Cinema Studio, every setting
This page lists every control in Cinema Studio, what it does, and its limits. The options you see change with the model you pick, because each model (the AI engine that makes the video) supports its own lengths, frame shapes and resolutions.
For a walk-through from first prompt to finished video, see Direct a video in Cinema Studio.

FAQ
Why can't I pick 30 seconds or 4K on my model?
Each model only offers the lengths, frame shapes and resolutions it supports. Switch to a model that lists the option you need.
What does the seed do?
The seed is a starting number for the model's randomness. Leave it on auto for different takes; set the same number to get closer repeats.
Can I choose the frame rate (fps) in Cinema Studio?
No. Cinema Studio has no frame-rate setting; you choose length, frame shape and resolution.
Why does a model say No sound?
That model makes a silent video. The studio warns you with the line No sound - this model creates a mute video.
