There are many out there who never turn theirs on and a lot of the time the feature goes unnoticed. Turning on autoplay for your featured video is very easy and the images below show you how: First click Edit Channel at the top, next click the featured tab and then check the Enable Featured Tab, once done click Finished Editing. Next on your channel click the Edit button as seen in the second picture above. In this new panel select the video you would like featured and on autoplay from your playlist(s) and then check on Automatically start playing the video once the channel has loaded and then proceed to click Apply as seen in the last image above. You will now have your featured video on Autoplay. Hope this helps anyone who noticed the feature or thought about using it, it will bring you a whole lot more views from those visiting your channel.
