SeaArt Lite Image to Video Model
By uploading two images as the first and last frames, you can generate a video with controlled start and end scenes, ensuring smooth dynamic transitions.
**Note:** 1. The first and last frames should be as similar as possible for a natural video transition. 2. Prompts are optional; it's recommended not to fill in prompts when you have both first and last images. If prompts are needed, try to describe a reasonable dynamic transition.
