Long ago, fanpop did briefly have the ability for users to đăng tải video to the site, but almost nobody used it, so the staff removed it about a tháng 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 thêm information, bạn might read the

That said, I would strongly recommend that bạn use a different video service than YouTube...depending on what bạn are trying to do. YouTube, now owned bởi Google, is constantly changing how video are handled and presented on other sites. In particular, YouTube is terrible for posting video to pop câu hỏi kiểm tra các câu hỏi (the các câu trả lời to the các câu hỏi are usually in the tiêu đề of the video, and now YouTube embeds the video tiêu đề with the video on other sites) and also bad for posting video involving any content that might be copyrighted (music videos, movie trailers, TV hiển thị clips, etc. - YouTube is very quick to remove such content, which then makes for broken đường dẫn all over Fanpop). So, while bạn can use YouTube to post your own personal videos, if bạn want to, say, create a fanvid, I recommend posting it elsewhere, such as on Flickr, Vimeo, hoặc Dailymotion.
