# MiniMax H3 INT8 Reference-to-Video ## Summary `MiniMax-H3` reference-to-video workflow with `INT8`, Motion Context, a dedicated reference LoRA path, and latent upscaling. This is the most practical same-day MiniMax consistency-oriented update. ## Model Family - `minimax` ## Status - `imported-only` ## Source - Workflow repo: - Workflow file: - Original publisher: `javawock7618` - Date imported: `2026-08-13` ## Developer notes - This is the `R2V` branch from the source pack. - The source README describes the pack as using `Sage-Attention`, `Spectrum`, `Lightx2v LoRA`, experimental `Turbo-LoRA`, `Motion Context`, and latent upscaling. - The `R2V` branch expects `minimax_h3_ref_lora_rank_256_bf16.safetensors`. ## Our notes - This is the strongest today-only `MiniMax-H3` workflow for actual consistency and reference control. - It is still heavy for an `RTX 3070 / 8 GB`, but it is much more interesting than a novelty-only turbo drop. - If you want one MiniMax workflow to test against `LTX 2.3`, this is the one. ## Required custom nodes - `ComfyUI-Spectrum-MiniMax-H3` - `ComfyUI-H3-Motion-Context` - `ComfyUI-MiniMaxH3_LatentUpscaler` ## Required model files - `Comfy-Org/MiniMax-H3` - `minimax_h3_ref_lora_rank_256_bf16.safetensors` from `Kijai/MiniMax-H3-experimental` - optional `Kijai/MiniMax-H3_comfy` - optional `drbaph/MiniMax-H3-Turbo-Lora-ComfyUI` ## Notes - This is the better `MiniMax-H3` pick when you care about reference fidelity, not just speed. - The pack also ships FLF and TTS workflows, but this import is the dedicated R2V graph.
