Open-Source ComfyUI Timeline Node Turns H3 Video Extension Into a Mini Video Editor
obvpm · reddit · 2026-09-22
Reddit user obvpm released comfyui-obvpm-timeline, open-source ComfyUI nodes that bring a mini video-editor timeline to MiniMax H3 video extension workflows (built on top of NikoDemon80's ComfyUI-H3-Motion-Context nodes).
Highlights:
- Compose video extensions directly in the workflow and instantly see whether segments flow seamlessly — solving the cumbersome UX of the original H3 nodes;
- Supports extend, prepend, bridge, cut, loop, and upscale;
- The author also open-sourced the general-purpose comfyui-obvpm node set, recommending the Value Presets node in particular;
- A demo video explains how the timeline node works.
