MiniMax H3 Official I2V

Summary

Official MiniMax H3 image-to-video template from the Comfy workflow templates. Good baseline for seeing how the official Comfy packaging expects MiniMax to be wired.

Developer notes

• The model card lists several pruned and scaled model variants, including pruned_fp8_scaled files, which are the most interesting ones for tighter hardware.
• The official card also separates diffusion models, text encoders, and VAEs clearly, which is useful when wiring custom local setups.

Our notes

• This is the safest MiniMax baseline we have.
• On a 3070, MiniMax still looks tight to heavy, but the pruned/fp8-scaled model variants make it worth keeping on the board.
• If MiniMax becomes practical for you, this official workflow is the best starting point before moving into community turbo variants.

Required custom nodes

• current official Comfy support for MiniMax templates

Notes

• Best first official MiniMax import.
• Most relevant low-VRAM angle is choosing the pruned/fp8-scaled files from the model card rather than the heavier variants.
