MiniMax H3 Ref2V 6x 80GB

https://youtu.be/SUJkkT6XLHI This workflow is the 80GB full-configuration reference-to-video acceleration version for MiniMax H3. It is the high-memory option in the Ref2V group and is meant for users who want the most headroom when testing reference-driven video generation. The inspected graph uses a MiniMax H3 Ref2VA pruned INT8 ConvRot model, Qwen3-VL MiniMax NVFP4/AWQ text encoding, MiniMax H3 video and audio VAEs, a connected MiniMaxH3ReferenceToVideo node, turbo LoRA acceleration, and SaveVideo output. This package is meant for practical ComfyUI and RunningHub users who want a ready-made MiniMax H3 graph instead of rebuilding loader, encoder, VAE, sampler, and video export connections by hand. The workflow is especially useful for speed comparison, hardware planning, and repeatable prompt tests. Keep the same source image and prompt when comparing versions so the difference you see comes from the workflow route, not from changing creative variables. Main features: - MiniMax H3 reference-to-video workflow for 80GB-class hardware - Full-configuration member of the Ref2V acceleration group - Reference-to-video control path is connected to the output - Pruned INT8 ConvRot Ref2VA model route - Qwen3-VL MiniMax encoder with MiniMax H3 VAE components - Euler sampling with beta 6-step schedule - Best used as the high-memory comparison route against 24GB and 48GB versions Suggested workflow: Use this version when you can run a high-memory GPU and want to stress-test reference consistency. Keep the reference material identical to the lower-memory tests, then compare output stability, subject identity, scene adherence, and motion quality before choosing the production route. For better comparisons, make one small test first, review identity stability and temporal motion, then raise prompt complexity only after the base route behaves correctly. When using speaking-character prompts, keep the face visible, avoid too many fast cuts, and separate action, expression, and camera instructions clearly.
