Tech question, please help

Hi
Can anyone of the forum tell me why
videogames\' motion looks choppy below 30
frames p/sec and live action looks just fine at
only 25 frames p/sec ?

Thank U.

I was informed that a 60 hz T.V. is capable of displaying a max of 30 fps. So, what is all the hubub about 60 fps?

televisions that run at 24.5 frames per second use motion blurring techniques, and games do not

The standard speed for motion picture photography is 24 fps, not 25.  Ordinary video on an NTSC tv is 30 "full" images per second, made up of 30 frames (or fields) containing the odd numbered lines in the image, and 30 containing the even numbered lines.  Thus it takes 60 cycles per second to construct 30 full images on the screen.  That is how interlaced video works.

So, your question remains unanswered, Zavijava.  Here\'s a restatement for the TRUE wizards out there (ahem, Videoholic...):  If game developers are supposedly shooting for "60 fps," why bother when the NTSC tv will only display 30 full frames per second anyway?  If they put a different image in the odd numbered lines as opposed to the even lines of the game video, wouldn\'t that produce the "combing" effect common to interlaced DVD players?  The PS2 doesn\'t produce progressive video when running games, does it?
