+# MiniMax H3 Steffalkok I2V PDD-Acc
+
+## Summary
+
+Same-day `MiniMax H3` image-to-video workflow from StefanFalkok, using the `PDD-Acc` turbo node path.
+This is the companion import to the new ref2v workflow.
+
+## Model Family
+
+- `minimax`
+
+## Status
+
+- `imported-only`
+
+## Source
+
+- Model card: <https://huggingface.co/StefanFalkok/Minimax_H3_Workflows>
+- Workflow file: <https://huggingface.co/StefanFalkok/Minimax_H3_Workflows/resolve/main/Minimax%20H3/Minimax%20H3%20I2V%20%28with%20PDD-Acc%208-Steps%20Turbo%20Nodes%29.json>
+- Original publisher: `StefanFalkok`
+- Date imported: `2026-08-28`
+
+## Developer notes
+
+- The source pack positions these as practical ComfyUI workflows for `MiniMax H3`.
+- The same repo also includes a plain I2V workflow and a longer-video beta pack.
+- The author credits `Comfy-Org/MiniMax-H3` for the model files.
+
+## Our notes
+
+- Useful as a lower-friction community I2V variant if you want a turbo-node route rather than the official baseline.
+- Still likely tight on a `3070`, but the workflow is interesting enough to keep as a reference point.
+- This is the companion import to the ref2v workflow above, not a separate new lane.
+
+## Required custom nodes
+
+- `ComfyUI-MiniMax-H3-Turbo`
+- `ComfyUI-MiniMax-H3-PDD-Acc`
+- `ComfyUI-MiniMax-H3-LongMedia`
+
+## Required models
+
+- `Comfy-Org/MiniMax-H3`
+- matching `MiniMax H3` text encoder
+- matching `MiniMax H3` VAE
+- optional turbo LoRA files used by the graph
+
+## Notes
+
+- Best new same-day MiniMax H3 import for image-to-video.
+- Good companion to the repo's existing official and INT8 MiniMax workflows.

+# MiniMax H3 Steffalkok Ref2V PDD-Acc
+
+## Summary
+
+Same-day `MiniMax H3` reference-to-video workflow pack from StefanFalkok, using the `PDD-Acc` turbo node path.
+This is the more interesting of the new imports for reference control and identity continuity.
+
+## Model Family
+
+- `minimax`
+
+## Status
+
+- `imported-only`
+
+## Source
+
+- Model card: <https://huggingface.co/StefanFalkok/Minimax_H3_Workflows>

+- Original publisher: `StefanFalkok`
+- Date imported: `2026-08-28`
+
+## Developer notes
+
+- The source pack explicitly calls out `FL2VA` and `Ref2Video` workflows with turbo LoRA nodes.
+- The author says all models come from `Comfy-Org/MiniMax-H3`.
+- The pack also points to companion prompt-generator workflows and a longer-video beta variant.
+
+## Our notes
+
+- This is the better MiniMax H3 import for your current taste because it is directly about reference-driven video, not just generic generation.
+- Still likely heavy on a `3070`, but the `PDD-Acc` turbo path makes it more worth testing than a brute-force baseline.
+- Good candidate if you want a practical reference-control starting point that can sit beside the existing MiniMax imports.
+
+## Required custom nodes
+
+- `ComfyUI-MiniMax-H3-Turbo`
+- `ComfyUI-MiniMax-H3-PDD-Acc`
+- `ComfyUI-MiniMax-H3-LongMedia`
+
+## Required models
+
+- `Comfy-Org/MiniMax-H3`
+- matching `MiniMax H3` text encoder
+- matching `MiniMax H3` VAE
+- optional turbo LoRA files used by the graph
+
+## Notes
+
+- Best new same-day MiniMax H3 import for reference control.
+- Use this when you want a community workflow source rather than the official baseline.
