MiniMax H3 Ref2VA Two-Stage Multi-Reference Redraw

Purpose: the two-pass multi-reference redraw. Multi-reference conditioning runs PASS 1; one pixel-space RTX upscale carries the video into PASS 2, which is re-conditioned at the actual upscaled size with the 4-step turbo LoRA at low denoise. The saved note calls this the V2 fix: PASS 2 no longer inherits PASS 1's old conditioning size.

How to use

This is the cheaper multi-reference option — one upscale instead of two. Check the RTX multiplier and the PASS 2 conditioning recompute, then keep PASS 1 audio for the export. If you need more detail than this produces, move to the three-stage file rather than tweaking denoise blindly.

Limits and not-verified items

No inference was run for this listing: no speed, VRAM or reference-consistency claim is made; values are quoted as saved. H3 weights, LoRAs, encoder and VAEs are not bundled. Source notes carry third-party attribution (MarkDKBerry.com); preserved as-is, no originality claim. The cover image is a promotional still, not a frame produced by this graph.
