Animation teams must consider many different things when creating a run cycle for an athlete. For example, the character’s design and running direction may determine what type of movements you’ll need to capture in your animation pipeline. Is he or she overweight but graceful while still being able to outrun someone pursuing him/her? Or would it be more appropriate if this person were thin with quick reflexes so they could get away from danger quickly?”
A fascinating video teaches how to animate a running cycle. The tutorial includes tips and tricks from the animator Chiara Porri, including what software she uses in her workflow! You can find out more about it on this page: https://longwinterstudiosblog.com/2018/06/run-cycle-tutorial.
