How do you train a LoRA?

A user identified as yuil12 on Hugging Face's discussion forum reports that their LoRA (Low-Rank Adaptation) training for AI video models is producing blurry and unrealistic results, and asks how professionals handle LoRA training and what mistakes they might be making, noting a lack of solid information in open sources.

yuil12 https://discuss.huggingface.co/u/yuil12 1 I’ve started creating AI models, but I’m currently stuck at the LoRA training stage; my videos are turning out blurry and unrealistic. I’d like to know how the pros handle this and what mistakes I might be making, as I haven’t been able to find any solid information in open sources.
