Interesting question… A "jiffy" is actually the time it takes for one vertical retrace on a VGA display. It's a hard-wired event that happens once every 70th of a second. When Jim Kent wrote Animator and Animator Pro, he felt much more comfortable working within the native constraints of the VGA hardware, and didn't feel comfortable getting into real-time conversion. That was too bad. When we rewrote 3DSr2, on the other hand, Dan Silva managed to figure out how to do the jiffy->realtime conversion and we put the realtime "locking" code into the 3DSr2 previewer. Unfortunately, that was AFTER Animator Pro was shipping. So, if you NEED to play a flic at exactly x fps, you'll have to use the Flic playback code within 3DSr2 to do it. – G
