We don't allow the direct embedding of YouTube, Vimeo or other external site videos in AT2. The reason for this is because we don't want the advertisements and other playlists in these systems to show to Clients on our system. We also have a quality control on videos and this is maintained by uploading your files directly to our servers.
However, if you have videos on YouTube, Vimeo or other sites, that you would like to upload to your AT2 Profile, we have a solution for you!
1. Use the following links to rip these videos from these external sites. Given it is your own content, this isn't breaching any laws.
http://keepvid.com/ (this site supports downloads from over 50 different sites including Facebook, Vimeo, YouTube etc)
http://www.clipconverter.cc (this site allows you to enter the video link from YouTube, Vimeo etc and will start auto download to your computer)
2. You can then upload these files directly to the VIDEO tab of your AT2 Profile as long as they are under the 50MB file size limit (See this article for more help Click Here for Help with Videos on AT2)
