## Developer notes

- The source README describes this as the `First-Last-Frame` workflow.
- It uses INT8, Sol-Attn, Spectrum acceleration, Motion Context, Lightx2v LoRA, Turbo LoRA support, and latent upscaling.
- The pack says the FLF workflow is the one that uses Motion Context.

## Our notes

- Strongest new MiniMax import for controlled transitions and scene morphing.
- On a `3070`, this looks tight to heavy, but the INT8 path is the only reason it feels worth trying locally.
- Good candidate to compare directly against LTX first-frame or multi-reference workflows.

## Required custom nodes

- `ComfyUI-SolAttn_triton`
- `ComfyUI-Spectrum-MiniMax-H3`
- `ComfyUI-H3-Motion-Context`
- `ComfyUI-MiniMaxH3_LatentUpscaler`

## Required models

- `Comfy-Org/MiniMax-H3`
- `Kijai/MiniMax-H3_comfy`
- `drbaph/MiniMax-H3-Turbo-Lora-ComfyUI` if the turbo path is enabled

## Notes

- Best same-day MiniMax workflow for first/last-frame control.
