Getting started

Add your folders and let x4u get to work.

Add the folders that hold your videos in Settings. x4u finds every video in them and works through them in the background: it reads each one, takes its fingerprint, asks StashDB what it is, and makes a thumbnail and a short preview. The bar at the top of the page shows how far it's got.

A big library takes a while the first time, from minutes to hours, most of it making previews. You can watch anything in the meantime. Afterwards only new videos need this, and x4u looks for them when it starts and every hour.
