AI Video Generation Guided by 3D Previs
Give the video model a shot you have already tried in 3D, then describe its materials, lighting, and style. AI Render uses the current timeline as a video reference. Compare the result with the preview, and return to the scene to refine framing, movement, or cuts when needed.
- 01
Review the preview
Check every shot in the current timeline, including framing, camera movement, and timing. Make sure the duration meets the model’s requirements.
- 02
Describe the look
Specify appearance, materials, light, and atmosphere, and add references as needed. The preview communicates the shot; the description develops its visual detail.
- 03
Review and refine the result
Check the generated video against your intent. Revise the description or return to the scene to make changes, then generate another version.
- Uses a preview of the full current timeline, in the pass you choose, as a reference.
- Combines visual direction and reference assets to develop the image.
- Previs guides composition and motion; it does not guarantee a frame-for-frame match.
- Renders are stored separately from the original 3D scene.
- The scene and camera remain editable.
An AI Director turn is billed from model usage and draws only director credits. 10 credits is a usage example, not a fixed rate or spending cap. AI Render draws only video credits. A MiniMax H3 render at 768p for 10 seconds is a budget example of about 20 video credits. Check the quote before submitting. The free plan includes a one-time grant of 50 director credits and no video credits. 3D playback and preview exports are free.
Can previs precisely control an AI video's camera?
Previs provides a more specific spatial and motion reference than a prompt alone, but frame-for-frame adherence is not guaranteed. Compare subject size, foreground direction, orbit angle and cuts at matching times after generation.
What should I change when the camera misses the reference?
Replay the preview and verify camera position, path and look-at target first. If the reference is correct, record the current model, duration and visual direction. Change one part of the reference or description on the next attempt, then compare.
