You'll have to download the package to get the templates because the above image is NOT large enough to fit your One Channel. If I made the preview image full size, it might cause browser display problems.
May 28, 2014 update: I updated this pack to include a JPEG, to make them easier to work with and to make them a lot prettier to look at.
Included in this package are:
A JPEG Template
A PNG Template
A GIMP project file template
A Photoshop project file template
The preview image I made for deviantArt so I don't lose it, ha ha!
I included a bunch of image and project file formats to try and cover as many common bases as possible. Pick the one you would like to work with and feel free to chuck the rest to save disc space.
The Youtube "One Channel" design displays differently depending on the device you look at them on and/or the resolution of said device(s).
The whole image is shown when viewing it on a TV. You have to make channel art to at least the resolution of 2560x1440. Any widescreen (16:9) image will work, but it's just easier to estimate where things will land if you use a size that conforms like this.
The gray gradient boxes across the center indicate the general range of what will display on other devices. The "safe area" is the spot where people will always see no matter what they use. So put logos, text, etc... whatever is important in this area. Remember to take into account the range your icon and social/website links that might overlay the area depending on the width/device so stuff doesn't get covered you don't want covered.
Tips on creating channel art:
-Keep in mind that the template is just a loose guide since they scale the image anyway and the lines will never be exact as a result of their scaling. So put important things like 2-4 pixels away from the edges of the "safe area" in the center not covered up by links or your icon.
-Horizontal composition of your art across that center line is typically best because it'll look good at all widths.
-Having issues composing something? Try to make it abstract! Because an abstract style doesn't typically have any focal point, they can be looked at from any spot and still be appealing.
-If you want to put your name in the channel art somewhere but not have enough room, a thing you could consider is putting your name in your channel icon instead because it always overlays the channel art anyway.
Enjoy creating your channel art!
