MiniMax H3 Easy-Use Workflow

T2VA and I2VA (first + optional last frame). Organized in four stages — MODELS → PASS 1 → PASS 2 → ENHANCE. Fast Turbo hybrid first pass at 0.2 MP, then 2× latent refine, FILM to 48 fps. High quality without touching the heavy SR/sharpen nodes unless you want them.

Leave both image loaders bypassed for T2VA. Un-bypass FIRST FRAME for I2VA. Un-bypass both for first-to-last.
