I just wish you would also have discussed, why 25 FPS is also a common standard in animation and how animation on doubles and singles have a further effect on our resources as well as on the end result.
HI Hochelf,
Thanks for the feedback. 25 fps is only common in countries that use the PAL system for their Television. (which runs at 25fps)
AS for animating on 1s and 2s, sadly I can't fit everything I want into a lesson ;(
