I'm putting together a very basic software to animate a few pixels frame-by-frame. I've skimmed through Richard William's Animator's Survival Kit in the past and noticed most traditional animation uses 24fps and he used to "animate on twos" for most motion and on "ones" for fast motion.
Since my tool will deal with frame by frame animation I'd like to make use of those principles, but I am constraint to 30 fps. Because of this, I'm wondering how would I workout at what frame interval(every frame, every two frames, every three frames, etc.) a 'keyframe'/changed frame should be placed to look good ? Is there a way to work that out arithmetically ? Does it make a bit difference/ is it safe two stick to twos even for 30fps ?
