These are Motion LoRA for the AnimateDiff extension, enabling camera motion controls! They were released by Guoyww, one of the AnimateDiff team.
Download them to the normal LoRA directory and call them in the prompt exactly as you would any other LoRA, while AnimateDiff is enabled. Note that they will only work with the v2 Motion Modules.
