MiniMax H3 Ref2VA multi-reference + keyframe story control, with Motion Lab action repair - a single ComfyUI workflow that turns multiple reference pictures into one coherent cinematic video.

This workflow is built around the MiniMax H3 Ref2VA model (minimax_h3_ref2va_int8_convrot.safetensors) and drives it through a multi-pass SamplerCustomAdvanced pipeline with res_multistep sampling, a Qwen3-VL 32B text encoder (qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors), separate video VAE (minimax_h3_video_vae_fp16) and audio VAE (minimax_h3_audio_vae_fp32), plus a compatible 3D latent upscaler pass at 1.5x before the final save.

Main features:
- Multi-reference fusion: bind subject, outfit, environment and prop to <Picture N> slots in the prompt so identity stays consistent across shots.
- Keyframe story control: anchor specific frames to narrative beats inside one continuous generation.
- Motion Lab action repair: fixes motion artifacts on fast-action sequences.
- Two-stage output: an 8-second PASS1 preview plus the final AllInOne video, with a 3D HiRes 1.5x upscale pass before saving.

Suggested workflow:
1. Load your reference pictures (subject / outfit / environment / prop) into the image slots.
2. Write subject_definitions for each <Picture N>, then one summary line describing the full sequence.
3. Run PASS1 to check composition, then run the final pass with the 1.5x 3D upscale enabled.

Notes: 5 output-reachable nodes are intentionally bypassed in this build; their effects are disabled by design. Requires MiniMax H3 Ref2VA int8 weights, the Qwen3-VL 32B encoder and both video/audio VAEs.
