To add a trailer, click the "Edit Profile" link at the top of your project profile page, then copy and paste the link to your video from You Tube or Vimeo into the field labeled "YouTube or Vimeo link".
If your video is password protected, you'll need to type the password to view the video in the field labeled "Video password (if needed)." Your video should also have sharing enabled on the site on which it's hosted.
When your trailer is successfully uploaded, you will see it at the top of your project profile page.
