Frame Forge Update: A Timeline UI on ComfyUI for Chaining Minimax H3 AI Videos

Super_Range45 · reddit · 2026-10-10

Frame Forge (aka Chain Motion AI Video Editor) ships its first update: an open-source UI layer on top of ComfyUI designed to make chaining Minimax H3-generated video clips into a coherent film more intuitive.

Features include reference-organizing tools, a timeline editor for piecing together prompt-by-prompt sequences with quick iteration, a Scene Writer that uses local or closed LLMs to draft prompts in a suggested format, Motion Continuation, a Pose Studio with Qwen 2.1 integration, and a Voice Studio powered by LTX 2.3. Videos can be generated locally or via Comfy cloud credits.

The workflow idea: compose video sequences on a timeline, iterate fast, and make precise edits with minimal friction.
