## Developer notes

- The pack README describes this as the `Reference-to-Video` workflow.
- It is built around INT8 inference, Sol-Attn, SLA-Attention, Spectrum, Lightx2v LoRA support, optional Turbo-LoRA, native Extend support, Fun ControlNet Union V2V control, and latent upscaling.
- The workflow uses the pack's dedicated reference LoRA path for appearance retention.

## Our notes

- Best new MiniMax H3 import today if you care about reference retention more than flashy motion.
- This is the right kind of update for the current watch area because it is practical control, not just a decorative LoRA.
- Still heavy on an `RTX 3070`, but the INT8 path is the main reason it is worth trying locally.
