Lightroom is using up a chunk of C drive storing media cache files for some video clips that I have in with the rest of my media. As of now, I don't have any plans to use lightroom to edit video clips. Is there any way to have lightroom ignore video files and prevent it from generating all these video cache files?
You can easily delete the media cache files using normal OS delete command. Any video file already in Lr catalog are easily removed. Remember to use the 'Remove form Catalog' option not 'Delete form Disk'. In future, the video files can be unchecked in Import window. This prevents them from being imported into Lr. However, you'll need to copy them to your hard disk manually if on a flash card.
there is no way to tell LR to just never import videos into the catalog other than by manually excluding them/removing them with each import?
