Fill the motion between a first and a last frame
Pick a start image and an end image and describe how things move. You get a video that goes from one to the other. The end image is optional. Use it to connect two manga panels, or for transformations and scene transitions.

What you put in, what you get
You provide
- Start image (PNG, JPEG or WebP; short side at least 300 px; aspect ratio between 1:2.5 and 2.5:1)
- End image (optional; works best with the same aspect ratio as the start image)
- How it moves (required, e.g. "turns around, waves and walks toward the window")
- Length: 3, 5, 7 or 10 s (some models round to their nearest supported length)
You get
An MP4 that moves from the start image to the end image. Without an end image, it animates the start image as described.
Good for
- Connect two manga panels with a short clip
- Make the moment a character's expression or pose changes
- Fix the first and last shot of a scene, then generate the motion between them

FAQ
Do I need an end image?
No. Without one, the start image is animated as you describe (image to video).
How long can the video be?
You can pick 3, 5, 7 or 10 seconds. Veo 3.1 Fast makes 4, 6 or 8 seconds and Kling 2.6 Pro makes 5 or 10, so they use the nearest supported length at or above your choice.
Does it include sound?
Veo 3.1 Fast generates sound. Kling 3.0 and Seedance 2.0 do not.
Can the start and end images have different aspect ratios?
Matching aspect ratios work best. Different ones can make the motion in between look unnatural.
How many credits does it use?
For 5 seconds: about 352 with Kling 2.6 Pro and about 564 with Kling 3.0 Pro (as of October 30, 2026). The estimate shows the exact amount before you generate.
