Re: How exactly does 23.98 video work?

"23.976" and "23.98" video is actually 24 * 1000 / 1001 frames per second. 23.98 is generally understood to refer to that, since there is no 23.98000 fps format. 29.97 video is 30 * 1000 / 1001 frames per second.

For 23.98 you also have to use non-drop frame timecode, which doesn't keep in step with real time.

2- I believe they don't broadcast HD at 30.00fps since you'd run into all sorts of sync issues. To simulcast HD and SD at the same time, it's easier if both were at the same frame rate.

It's pesky and annoying, but it's a problem you can overcome.
