Persistence of Vision

T-PRIN-001-002

Persistence of vision is when your eye's retina retains an image for a fraction of a second before replacing it with a new image. If the images before you are moving fast enough, you'll have the impression that you're seeing both images at the same time.

This persistence of vision allows us to "fill in" movement from one image to the next when viewing media on screen, which is usually filmed at 24 frames per second. In animation, it's also typical for an animator to use 24 images for one second of screen time.

We recommend that you, as a beginning animator, use 12 frames per second when you're working on your projects. In studio production, you will work in 24 or 25 frames per second.
