It needs to be done in Illustrator or some other vector art program that can save files as an .ai. You can import AI files into Motion and if set right you can maintain its vector quality.
Your Illustrator file needs to be RGB and not CMYK. Be sure to save the AI file with PDF compatibility. After you bring it into Motion, just select it, press Shift+F (takes to you the Media tab), then uncheck the Fixed Resolution checkbox. This will allow the vector image to be rasterized at whatever size it is on-screen. Hope this helps.
If you are doing Photoshop then you’ll want it to be built bigger then your working area. Don’t go bigger then 72 dpi. TV is 72 dpi so any bigger dpi will just slow down Motion and not give you any extra quality. Remember, the bigger the image the more is will play sluggishly.
Hope this helps.
