Summary

Alpha Gen is a VFX tool that automatically generates alpha mattes from RGB video clips without requiring green screens, masks, or prompts. It specializes in difficult-to-key elements like hair, fur, smoke, and water, with both a faster distilled model and a full model for complex scenes, available in ComfyUI.

The last drop of VFX Week: Alpha Gen (Beta). Give it an ordinary RGB clip and get back an alpha matte that matches your plate frame for frame. No green screen, no masks, no prompt. Built for the edges that are hard to key or roto: hair, fur, smoke, fire, glass, water. 🧵
#2
Two workflows are included: Distilled model, for faster runs. Runs in ComfyUI today. Full model, for more complex scenes, currently limited to shorter clips. Its ComfyUI workflow is coming soon.
#3
Alpha Gen's matte drops in as the alpha channel of your original clip, so soft edges and translucent surfaces blend into your comp. Or export RGBA / ProRes 4444. Everything else stays as is.
