What image to video actually does
The model keeps your image as the first frame and predicts the next seconds of movement from your prompt. The better the image — sharp, well lit, subject in frame — the more natural the motion.
Quality and length
Resolution and length depend on the model: Seedance 2.5 Spicy goes up to 4K and 30 seconds with sound; Wan 3 Spicy up to 1080p and 30 seconds with sound; Wan 2.7 Spicy 720p or 1080p in 5, 10 or 15 second clips. Test at a lower resolution, then re-run the keeper in higher quality.
