Improving realistic fighting scenes with Minimax H3 and R2V
FreddyShrimp · reddit · 2026-08-19
A user is trying to generate realistic street fight videos using Minimax H3 (int8 convrot) via a ComfyUI R2V workflow. Despite providing reference videos of the two subjects and proper punches, the generated scenes lack impact, with punches failing to land convincingly. Running on an RTX 5090 at 1.0MP (2:3 aspect ratio) with 20 steps, the user seeks technical advice and questions whether training a LoRA is necessary to resolve this common issue with physical contact in T2V/I2V.
