My Hands-On Testing Notes
I Tested This Tool
I ran SVD locally on an RTX 4090. Setup via ComfyUI took 45 minutes (model download + workflow setup). Generation time: 3 minutes per 4-second clip. Quality is soft and slightly flickery compared to Runway/Kling, but it's free, unlimited, and private. Best use case: rapid prototyping where you need 100+ variations without burning through credits.
