ComfyUI Node Adds Two-Stage AI Director Pipeline for Multi-Character Video Prompts

1038lab shipped ComfyUI-MiniMax-H3-Promptor v1.3.0, rebuilding multi-reference video prompting as a two-stage "AI director + screenwriter" pipeline to fix overlapping characters, stretched faces and pacing flicker in 15s generations:
- Stage 1: the LLM acts as showrunner — analyzing cast references, mapping foreground/midground/background layers, setting lighting, and enforcing a 2.5–4.0s minimum per shot to prevent pacing flicker.
- Stage 2: it builds timed cuts covering the full duration (up to 15s) and injects official MiniMax character dialogue syntax.
Other upgrades: an in-node HTML drag-and-drop panel replaces spaghetti wiring; Vision Analyzer V2 passes references at 100% original dimensions and cuts token usage/latency roughly in half; smarter entity regex (a "cat-ear headband" no longer spawns animals); sub-batch chunking respects API rate limits. Updatable via ComfyUI Manager.
