MiniMax H3 Lipsync Workflow: 1.4MP Takes 3-4 Hours on 5090

A reference workflow for MiniMax H3 lipsync videos using FL2VA + REF2VA Lora at 1.4MP and 20 steps takes 3-4 hours on a 5090, utilizing sparse attention and a 4B Qwen encoder. Using a Turbo Lora at 1MP + 8 steps reduces time to 20-30 mins. The video consists of 14x 15s clips to prevent degradation, though this causes clothing drift. The author suggests shortening clips to 7s for higher res and speed.
