How to Make Text-to-Video Prompts

1

Write Your Scene

Describe what happens on screen in plain language: the subject, the action, the setting, and the atmosphere. Concrete detail beats vague adjectives every time.

2

Add Camera and Style

Choose a camera movement like push-in or tracking shot, a visual style, and lighting. These directorial cues give Seedance 2.5 the context to frame the shot.

3

Export Your Prompt

Copy the finished prompt or the full API body and run it on any Seedance 2.5 endpoint. Save the seed if you want to iterate on a result you like.

Text-to-Video FAQ

How long can a Seedance 2.5 text-to-video clip be?

Seedance 2.5 renders up to 30 seconds in a single generation, with no stitching required. Shorter clips render faster and cost less, so match the duration to what your shot actually needs.

What makes a good text-to-video prompt?

Name a clear subject, one main action, and the environment, then layer on camera movement, lighting, and style. Avoid cramming in five unrelated ideas — one strong shot per generation gives the cleanest result.

Can I get 4K output from text alone?

Yes. Seedance 2.5 generates natively at up to 4K rather than upscaling, so pick the 4K resolution in the settings and it will be written into your request body.
