UlazAI - AI Image & Video Tools
New video-to-video tool
Upload a video. Keep the motion. Change everything else.
Motion Recast runs your clip through Seedance 2.5 with character, location and product references plus a preset, so the shot-for-shot edit survives while the world, cast or style is rebuilt.
Motion Recast bills measured source seconds plus output seconds at the Seedance 2.5 video-input rate: 17 credits/s at 480p and 38 credits/s at 720p. The workspace shows the exact price before every run.
Ad remixes: keep a proven edit and recast it for a new market or product.
Style swaps: turn live footage into anime, claymation or film noir without re-shooting.
Wardrobe and product swaps: change one element while people, motion and timing stay untouched.
Two modes
Swap one element
4 to 30 seconds
Keep the film exactly as filmed and change one thing only: a character, outfit, location, product or object.
Preset gallery

What carries over
The prompt asks Seedance 2.5 to hold the exact motion, acting, timing, camera movement and edit of your upload. Reference images steer the cast, the setting and the product; your preset and note steer the rest. The price is measured, not estimated: source seconds plus output seconds, shown before you generate.
How it works
- Upload one source clip of 4 to 30 seconds; the measured duration drives the price.
- Optionally add character, location and product reference images, up to ten per slot.
- Pick Keep the motion or Swap one element, choose a preset and an optional note.
- Review the exact credit price, generate, and compare result and original side by side.
