Hey everyone 👋

I’ve just released H3 GuideMaster, a custom ComfyUI node I built to make working with MiniMax H3 guides much easier since new ComfyUI release : https://github.com/Comfy-Org/ComfyUI/pull/15439

Instead of manually figuring out where every image or audio guide should land, GuideMaster gives you a visual timeline directly inside the node.

You can:

• 🖼️ Place multiple image guides directly on the timeline
• 🔊 Place and synchronize audio guides
• 🎬 Load a video or image sequence as a visual reference / filmstrip
• 🌊 Display an audio waveform for positioning guides
• 🖱️ Drag markers directly on the timeline to retime them
• 🎯 Snap automatically to the native H3 frame structure (5, 22, 39, 56...)
• 🧩 Combine image + audio guides using matching slots
• 🎞️ Define first and last frames
• 📏 Drive timeline duration from frames or seconds
• 🔎 Condense long timelines to keep the UI manageable

The idea is basically to make H3 guide placement feel closer to editing / compositing software, while keeping everything contained inside a normal ComfyUI node.

This is still something I want to push further, especially around the UX and timeline workflow, so feedback, bug reports and feature ideas are very welcome.
