OK, for what I know about this.
NTSC: is the standard for the US and Japan.
PAL: is used in mainly Europe.
Both have Pros & Cons to them, PAL runs at a higher res then NTSC, NTSC runs at 60 Hz and now PAL also runs at 60 Hz.
I live in the US, so I only use NTSC (and I think NTSC runs at 29.95FPS and a lot of NTSC DVD's run at 24.95FPS).
But the one thing I wonder about is:
If NTSC runs at 60 Hz and about 30FPS and older PAL runs at 50 Hz and at 25FPS, does PAL60 also run at 30FPS or at 25FPS?
Because both standards are interlaced (all odd lines are drawn first, then all even lines (so for the first pass, line 1,3,5,7,9 all the whey to the last odd line
are drawn, then for the second pass, all the even lines 2,4,6,8,10 all the whey to the last even line are drawn last).
So if you do the math:
Total FPS * 2 = Hz (the two is for how many passes to make one frame on an interlaced TV)
OK, for NTSC about 30FPS * 2 = 60 Hz, and for PAL 25FPS * 2 = 50 Hz get it?
So does PAL60 run at 30FPS?
