Full video tutorial: every setting explained, plus the 12 GB VRAM setup step by step: https://youtu.be/UBgrzyj1sfg The fastest MiniMax H3 setup I've found: the lightx2v 4-step turbo LoRA + the FastVideo sparse attention (VSA) gate + the Semantic Bridge adapter, text to video and image to video with native audio in one graph. Measured on my test GPU (RTX A4500 20 GB, PyTorch cu130): Text to video, 5 s, 640x960 (0.6 MP): 0:55 sampling, peak about 12.8 GB VRAM (a 12 GB limit still ran at full speed, 0:57) Image to video, 1 MP: 2:08 sampling, 12.2 GB peak (on 12 GB cards use 0.6 MP: 1:04, 11.3 GB
