I’ve uploaded a new tool, to hopefully help with timing out a scene. The idea is that you click a button to correspond with when you feel like your beats should be, and then the spacing of those clicks is recorded so that you can reference it for your animation. Thanks to Mike Clark on this one, for motivation and helping flesh out the idea. ml_stopwatch is on the Tools Page.
If you get an error about ml_utilities with this script, you probably just need to download the latest ml_utilities.py.
