How to control AI camera movement with a drawn path

Camera direction does not have to live only in the prompt. In my test, a red line on the reference image represented the camera route: Seedance 2.0 used that frame to produce three different 1080p moves. This is a visual steering cue, not an exact 3D camera path, so the resulting trajectory still needs to be checked.

How it works

Reference setup: the image defines the scene; the red line defines the intended camera route.

How to recreate it

Start with a reference frame whose composition is easy to read. Draw a high-contrast line from the camera's intended starting point through the subjects or toward the final position. Keep the route clear of important visual detail where possible.
Upload the marked frame as a visual reference and explicitly define the line as a camera trajectory, not an object in the scene. Also tell the model not to reproduce the line in the final video.
Describe one continuous move and the landmarks the camera should reveal. In the original tests, one move followed a fly and paused on characters, another delayed the reveal of a threat, and a third travelled through a wedding and details of a deal.
Judge route accuracy before judging polish. If the camera cuts across the path or drifts away, simplify the line, reduce the number of events or split a complicated move into separate generations.

Video walkthrough

Original experiment: three camera-path scenes generated with Seedance 2.0 at 1080p.

Camera-path prompt

Replace the landmarks with your own. The important part is defining the line as camera guidance that must not be rendered.

Camera routeEN
Use the image as the visual reference for the scene. The red line represents the camera trajectory: begin at its first point, move smoothly along the line, and finish at its final point. Preserve the reference composition, characters and environment. The red line is only an instruction for camera movement; do not show, draw or retain the line in the final video.

Models

Seedance 2.0

Seedance 2.0 was the model used for the original three-path experiment and the 1080p outputs shown here.

Seedance 2.5

The current Seedance option in Mixer AI for scenes that combine several kinds of references and input guidance.

FAQ

Does a drawn line guarantee an exact AI camera path?

No. It is a visual cue for a video model, not a coordinate-based path from 3D software. The model may simplify or alter the route.

Why can the red line appear in the generated video?

The model may interpret the annotation as part of the image. Define it explicitly as camera guidance and tell the model not to render it.

Can the camera route pass several subjects?

You can try it. The original test revealed several characters and scene details along one route, but more turns and events increase the chance of drift.

How is this different from a normal camera-movement prompt?

Text names the movement; a drawn path adds spatial guidance directly on the composition. That is useful when where the camera travels matters as much as how it moves.
