What is Stable Video Diffusion?
Stability AI's open-weight image-to-video model. Feed it a still image, get back a 25-frame clip with plausible camera motion and scene dynamics. Two variants: SVD (14 frames) and SVD-XT (25 frames). Image-conditioning only — no text prompt control over motion.
Pros & cons
Pros
- Surprisingly coherent short clips from a single still
- Lighter than Wan / Hunyuan — fits on 16 GB GPUs
- First widely-available open video diffusion model
Cons
- No text-prompt control over motion direction
- Outclassed on quality by newer Wan 2.2 / Hunyuan Video
