Long ago, fanpop did briefly have the ability for users to mettre en ligne vidéos to the site, but almost nobody used it, so the staff removed it about a mois after it was implemented.
So now users should use any video sharing site and then insert the URLs in the "Add a video" form. For plus information, toi might read the
link.
That said, I would strongly recommend that toi use a different video service than YouTube...depending on what toi are trying to do. YouTube, now owned par Google, is constantly changing how vidéos are handled and presented on other sites. In particular, YouTube is terrible for posting vidéos to pop quizz questions (the réponses to the questions are usually in the titre of the video, and now YouTube embeds the video titre with the video on other sites) and also bad for posting vidéos involving any content that might be copyrighted (music videos, movie trailers, TV montrer clips, etc. - YouTube is very quick to remove such content, which then makes for broken liens all over Fanpop). So, while toi can use YouTube to post your own personal videos, if toi want to, say, create a fanvid, I recommend posting it elsewhere, such as on Flickr, Vimeo, ou Dailymotion.
