About ComfyUI-MiniMaxH3-TimelineDirector

Lay clips, soundtracks, images and audio on one editable timeline for MiniMax H3 Reference to Video. This ComfyUI node pack renders them together. It splits long videos into segments and joins them in a single run, so faces drift less. You'll need a recent ComfyUI build, the H3 Ref2VA model, and some guides are Chinese-only.

Best for: Timeline editors who already run MiniMax H3 Reference to Video and want long-form or digital-human shots.

• Moves, trims, splits and snaps clips on a multi-clip timeline
• Sets each clip as Fixed Guide, Editable Reference or Boundary Only
• Continues each segment from the last one's AV latent tail to cut drift
• Runs two-stage sampling: low-res steps, latent lift, then high-res steps
• Locks original audio so lip-sync follows your uploaded soundtrack
• Exports and imports timeline presets, with or without the media files
