Access: Signed in Ask the Spatial Agent to generate a video from your description, or animate a scene in Studio and use its rendered video as a reference.

​
Choose how to start

Access: Signed in
  • Start in Chat to turn an idea into a video quickly. Describe the subject, action, camera movement, and visual style.
  • Start in Studio to arrange the scene and demonstrate how the shot should move. Render your animation, click Add to chat, and describe the finished look you want.
You can also ask Codex to carry out the Studio workflow through WebMCP.

​
Generate a video from a prompt

Access: Signed in
  1. Open New chat in the Project you want to use.
  2. Describe your video in the Spatial Agent’s prompt box.
  3. Include the subject, action, camera movement, and visual style. Add a duration, landscape or portrait format, and sound or dialogue when they matter.
  4. Send your prompt.
For example:
Mint generates the video and adds a playable result to the chat. You can also attach an image to guide the result. Explain how Mint should use it, such as the starting image or a reference for the product’s appearance.

​
Generate a video from a Studio animation

Access: Signed in Use Studio to show where subjects belong and how the camera or objects should move. A simple scene can provide the structure for a more detailed generated video.

​
Build and animate the shot

  1. Open your Project in Studio. Arrange the objects and add or position a camera to frame the shot. For a product video, start with a simple bottle shape on a pedestal.
  2. Select the object or camera you want to animate.
  3. Move the timeline playhead to the beginning, set the starting position and rotation, and click Insert keyframe.
  4. Move the playhead to a later time, change the object’s or camera’s position or rotation, and click Insert keyframe again. For example, move the camera around the bottle while keeping it in frame.
  5. Use Play preview to check the framing, movement, and timing.

​
Render the animation

  1. Click Render in the timeline.
  2. In Render animation, choose the Camera and Animation.
  3. Set the Time range, resolution, and frame rate for your output.
  4. Click Render. Keep the Project tab open while rendering finishes.
  5. When you see Your render is ready, play the clip and wait for Saved to Renders.

​
Add the render to Chat

  1. Click Add to chat in the completed render dialog.
  2. Check that the rendered video is attached to the Project’s chat draft.
  3. Write a prompt describing the finished look and how Mint should use the reference. Then send the message.
For example:
Add to chat attaches the reference. Sending your prompt starts the generation workflow.

​
Review the appearance Preview

Access: Signed in When you use a Studio render to guide the camera and movement, Mint first creates an appearance Preview from the render’s first frame. This image shows the intended materials, lighting, and visual style. When approval is required, review the image and ask for changes if needed. Click Generate Video when the Preview looks right. With automatic generation enabled, Mint continues after the Preview is ready. Editing a Preview returns it to review before final video generation. The appearance Preview guides the finished look, while your Studio animation guides the camera and motion. The generated video may vary from the reference.

​
Revise a generated video

Access: Signed in Continue in the same chat and describe what you want to change:
Mint carries forward the previous brief, settings, and original references unless you change them. You do not need to attach the original images again. If you started with a Studio render, it continues to guide the camera and subject placement. The previous take can also guide appearance; Mint tells you if it cannot be included as an extra reference. You can ask for dialogue suggestions before generating, such as “Can you suggest better wording?” Select a suggestion or say “use that” to apply it to the video you were discussing. Each revision creates a new video, so its frames may differ from the original.

​
Credits and troubleshooting

Access: Signed in Studio rendering, appearance Preview generation, and final video generation have separate Credit costs. Check the current render quote, generation settings, and any Credits or plan messages before continuing.
  • Add to chat is unavailable: Wait for Saved to Renders. If saving failed, use Retry save. Check the button’s message for a reference-duration limit or unavailable Project chat, and adjust the render or reopen the Project as needed.
  • The video is attached but generation has not started: Add your prompt and send the message.
  • Mint is waiting at an appearance Preview: Review it and click Generate Video when ready.
  • You want different camera movement or timing: Adjust the Studio animation, render it again, and attach the new render to your next prompt.
Next step: Use Codex with WebMCP

​
Generate through API or MCP

You can also generate videos through the Videos API or Mint MCP. Both support text, image, first/last-frame, and reference-guided clips, with duration, aspect ratio, audio, and preset controls. These generation endpoints start directly without an appearance Preview.
