MiniMax H3 → LTX-2.5 Fast Refine/Upscale (2-Stage AV Pipeline) - v3.0 Showcase

v3.0 — RIFE Motion Pre-Interpolation

Adds RIFE frame interpolation before the LTX refine pass — fixes ghosting/warping artifacts on fast-motion or action shots by halving the per-frame motion delta the video VAE sees.

- Doubles frame count + fps automatically to preserve original duration/audio sync

- Fully toggleable — off falls back to previous (no interpolation) behavior exactly

- Requires ComfyUI-Frame-Interpolation (Gourieff/Fannovel16 — install via ComfyUI Manager, search "Frame Interpolation")

Adds render time (roughly doubles Stage 2 compute) — worth toggling off for calm/static shots that don't need it.

ReActor face-lock/restore still not included — early access via Patreon above.
