       to scan the entire source on your specified frequency, but it's very slow for large sources. This is the most accurate way to find uploaded media with the tradeoff being that pairing a large source that's indexed frequently will result in you spending most of your time indexing. Only so many indexing operations can be running at the same time so this can impact your other source's ability to index.

-      Fast indexing takes a different approach. It still does an initial scan the slow way but after that it uses a secondary mechanism (either RSS or YouTube's API) to frequently check for new videos. This has the potential to be hundreds of times faster, but it can miss videos if the uploader un-privates an old video or uploads dozens of videos in the space of a few minutes. It works well for most channels but it's not perfect.
