Speed up animating with looping
Looping lets you preview your animation in real time.
Set up loop last to loop the last 2 seconds of your animation, it will update as you capture frames so you only preview the end of your sequence.
Loop single is great for small movements, many professional animators prefer this way of working.
Many options such as "include live" and "loop once" mean you can set up looping just how you like.
