Overview
- MagicMotion lets users control video generation with trajectory guidance
- Introduces dense-to-sparse trajectory conditioning strategy
- Works with any diffusion model without retraining
- Addresses problems of previous methods that relied on sparse control points
- Uses RAFT optical flow estimation and PnP sampling
- Achieves state-of-the-art results in motion controllability
Plain English Explanation
When you watch videos created by AI, you might notice they often look strange - objects move oddly or unrealistically. MagicMotion solves this problem by giving you better control over how things move in AI-generated videos.
