YouTube Video Editor Settings
All of your videos can be seen in YouTube's Video Manager page when logged in. Get to the Video Manager by going to the gear near the Uploads button at the top of the screen (there are also links from other screens.)
The Video Manager screen is where you can easily delete or change a video's privacy settings. Select the video and under the Actions pull down menu - select the action you desire.
Behind each video is an Edit button and a small arrow which takes the user directly to specific editor settings.
