Trying off & on yesterday I got the site to load, though filling out the form to set up an account failed repeatedly. Surprisingly I got an email with the new account info & a link to access their libraries. I couldn't reach the site for the rest of the day, so I tried this morning -- I did get through & managed to sign in, but the site was apparently so overwhelmed that it was inoperable for the most part. The sign up page was active & reachable just now when I tried it [2:48 PM Est 1/13/23].
TO use the clips you will need a video editor [NLE] that allows layers & transparency to do greenscreen work, or use them for titles etc. where you add text &/or graphics on top of the clip as a background. I downloaded one clip just to get an idea of the format etc.
