How Do Animators Time Animation?

How to time animation?

Recently a new student at Animation Apprentice asked me this question: "How do you decide on the number of frames you use for each shot?" Which is really a way of saying "How do you time animation?".

This is a good question, very commonly asked by junior animators - and a tough one to answer. The short answer is that it takes time, and patience, as a thorough knowledge of timing and spacing takes a while to acquire.

However, one simple approach is time out an action with a stopwatch, or the timer on your phone, to get an idea of how long an action will take. Some animators will count out "one one thousand, two one thousand"... to figure out how many seconds an action might take.

But the best system of all for newbies is to use live-action reference.
