Provide a clean reference implementation for MiniMax H3 based text-to-video generation.
Runtime profile
Source description
Workflow Goal:
Provide a clean reference implementation for MiniMax H3 based text-to-video generation.
This workflow focuses on simplicity, reproducibility, and education rather than including every available feature or optimizations. It reflects a tested baseline for producing high-quality videos from a prompt. Treat it as a starting point and adapt the prompt and LoRA stack for your preferred artistic direction.
IMPORTANT NOTE:
Validated using an NVIDIA RTX 2080 (8 GB VRAM) with 64 GB System RAM.
Low VRAM does not mean low hardware requirements.
MiniMax H3 Text-to-Video is computationally intensive. Even when GPU VRAM is managed efficiently, higher resolutions and longer videos can require substantial system RAM for memory paging and intermediate data.

Primary configuration.
Good visual quality, motion, effects and audio.
Very fast relative to the base model.
Slight slow-motion feel may occur at the beginning of some clips.
No hardware-specific attention optimizations used.
No SageAttention.
No other VRAM/speed optimization nodes or launch parameters required.
Reference workflow intentionally uses the standard H3/ComfyUI execution path.
