Stamp out fuzzy photos!
You scan to meet your animation needs and to keep your image file sizes within reason to avoid unnecessary render slowdowns. For our purposes, scanner dots per inch (DPI) are equivalent to video pixels per inch (PPI). The more dots in your scanned im-age, the higher quality the resulting video image will be ­ and the closer you can zoom in before revealing the pixel structure of the image or before the program invents pixels which soften< the enlarged image.

The modern standard definition NTSC CCIR 601/ D1or DV video image is 720 pixels wide, and at 72 pixels per inch yields an acceptably sharp image for broadcast display. If you printed it out on paper it would be about ten inches wide. An 8" X 10" photo scanned in landscape (wide) mode at 72 dots per inch will translate to 720 pixels and completely fill the standard definition video frame. We call this 100% size for convenience.

But more pixels also means bigger file sizes. We try to strike a balance between "enough pixels" to support zoom-ins which stay sharp, and resulting file size to avoid needless time rendering. There are some rules of thumb you can follow.
