Our review
Stable Video refers to Stability AI's open-source video models Stable Video Diffusion (SVD): generate short clips from an input image while preserving composition and subject, free to deploy locally and customize, often driven through ComfyUI — a cornerstone of open-source video generation.
In April 2026 Stability launched Stable Diffusion 4, whose API adds native text-to-video (10s clips at 30fps, ~$0.15/video second) and 8K image output. Compared with closed products like Runway and Kling, Stable Video's open-source route suits teams that want local control and their own pipelines.
