❓ Frequently Asked Questions (Google Featured Snippet Reference)

What is Parametric Trajectory Distillation (PTD) in MiniMax-H3?

PTD compresses the multi-step diffusion ODE trajectory into 4 or 8 deterministic mathematical steps, reducing render time from 11 minutes to 72 seconds.

How does Ref2VA prevent background degradation during character recasting?

Ref2VA decouples the foreground character latent space from background spatial tokens using SAM masks, ensuring the train interior and lighting remain unchanged.

Does this require training a new LoRA for every actor?

No, Ref2VA uses zero-shot reference embedding injection from a single high-resolution portrait photograph.
