This is off subject for the Thread, but to keep in the tradition of most other threads, I will post any way.
RE: 29.97 Framerate.
Not sure about that whole light flicker think, which was very creative at worst (maybe technically accurate- somewhere) but my understanding of the Framerate is this: 29.97 framerate is called drop-frame. 30 FPS is call Non-Drop. What this means in 29.97 framerate- you lose .03 of a frame everysecond. This allows the frame rate timing to keep up with "Real time" or clock cycles. (That's Clock as in tell time with a... not CPU Clock Cycles). So for non-broadcast video it doesn't really matter, but when things need to play on TV at a specific time and the time needs to fit into the Show format and not go over time for fear of a portion of the show cutting out mid sentence while the station goes to commercials and such, you need to compensate for true time. I'm not sure why true time cant be achieved with modern technology- perhaps there is a dark hidden closely garded secret in relation to the light flicker
. However, it is very similar to leap year as a method to adjust our clocks and calendar to the imperfections in measuring the length of the day.
