They are using LTX 2.5 for image-to-video conversion, with a 6-second clip taking approximately 18 minutes to generate. The user has attempted various configurations, including GPU-only settings and PyTorch for Apple Silicon, but the performance remains slow compared to research estimates and Nvidia hardware. They are seeking advice on how to optimize local generation times without resorting to cloud-based GPUs. AI
