Hi there folks! So i've been making some downfall parodies about my friends, however they've now requested something bigger - so now i have to mix something together from youtube clips, but i'm not exactly sure what's the easiest and best way of getting them. I've tried looking at some of the extensions for Chrome and Firefox, but people are reporting problems with them either not working or installing other things too on the pc. I know there's sources like Keepvid, i'm simply just not sure if i dare accept that KeepVidDownloader java warns me about when trying to use the site. Basicly what i need is: To be able to download youtube videos in in different qualities and extensions, has to be able to download HD if possible. Anyone here who's able to help a fella out?
