Developer notes

• The pack README describes this as the Reference-to-Video workflow.
• It is built around INT8 inference, Sol-Attn, Spectrum, Lightx2v LoRA support, optional Turbo-LoRA, 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.
• Still heavy on an RTX 3070, but the INT8 path is the main reason it is worth trying locally.
• Good comparison point against current LTX reference-control workflows.
