Switch the composer to Video and choose a method:
- Text: describe the scene, action and camera movement.
- First/last frame: upload a first frame and, optionally, a last frame; the model animates between them. On the canvas you can select an image and choose Set as the first frame.
- Omni reference: mix images, videos (MP4 or MOV) and audio (MP3 or WAV), and type @ in the prompt to reference each one.
A single clip uses either frames or references, not both.
