Choosing Your Featured Video
What video do you want potential customers to see when they visit your channel page? That's your featured video, and it's solely your choice.
To select a featured video, log in to YouTube and go to your channel page. Click the Edit button above the current featured video and make a selection from the listtypically Uploaded Videos (that is, videos you've uploaded, instead of videos from other users).
You can select a specific video from the resulting list, or opt to always display the most recent video in this set. You can also opt to have this video play automatically when someone visits your page, as well as prevent ads from displaying in the videos you display on this page. Click the Apply button when done.
