Developer notes

• This graph uses the native MiniMax-H3 ComfyUI node path and keeps the audio branch in the loop.
• The source card pairs the pruned int8-convrot diffusion model with the Qwen3-VL text encoder and separate video/audio VAEs.
• The workflow is built around the 17k+5 frame grid at 24 fps.

Our notes

• Best as a baseline if you want the faster MiniMax H3 route without getting lost in the bigger community packs.
• Still heavy for an RTX 3070 with 8 GB VRAM, but much more practical than the raw full-fat path.
• Good comparison point against the older MiniMax H3 templates already in the repo.

Required custom nodes

• Native ComfyUI MiniMax-H3 support

Required models

• Comfy-Org/MiniMax-H3 or the equivalent files referenced in the workflow
• minimax_h3_fl2va_pruned_int8_convrot.safetensors
• qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors
• minimax_h3_video_vae_fp16.safetensors
• minimax_h3_audio_vae_fp32.safetensors
• minimax_h3_fl2v_turbo_8step_v1.0_comfyui_bf16.safetensors for the turbo path

Notes

• Good same-day MiniMax H3 import if you want the leaner FP8/turbo setup.
