Open-Source ComfyUI Node Adds Visual Keyframe Camera Control Prompts for MiniMax H3
Emotional_Example_12 · reddit · 2026-09-13
- Developer NyckM released bruxosdovfx • Camera H3 v19.1, a visual camera editor inside ComfyUI for MiniMax H3 video generation: drag the camera, create keyframes, and the node compiles camera-path prompts.
- Note it compiles prompts, not a geometric adapter, so H3 tracking isn't guaranteed. v19.1 adds smooth/linear interpolation, timing redistribution, angle unwrapping (e.g. 350°→10°), 0.5s start/end holds, orbit/rise/dolly presets, diagnostics, and loop closure; a new subjectbox lets the camera orbit a chosen subject.
- Install by cloning into ComfyUI/customnodes; PT/EN UI and an Experimental variant available.
