I'm fairly up on all the jargon and what things mean etc but when i keep hearing about 5.5 pulldown im totally lost? what is this?
 
well even anyway...
 
it's actually smooth (equal/better than PAL DVD), if done properly.
 
Hi

The 5:5 pulldown is what the Americans use to convert 24p to make it suitable for their TVs which work at 120Hz.

24 x 5 = 120Hz. This is the American equivalent of 100Hz.

50Hz x 2 = 100Hz European
60Hz x 2 = 120Hz North America

The mains in America is 60Hz, in Europe its 50Hz.

5:5 is not exclusive to the U.S or 'NTSC' regions. UK sets can also convert 24p to 120p using 5:5.

24 x 5 = 120Hz. This is the American equivalent of 100Hz.

That doesn't make any sense.

What does the mains have to do with the TV's operating frequency?

24p is far from smooth, i'm not using PAL as a reference in that statement since the source for a PAL DVD is still the same 35mm film shot at 24 frames per second. 24fps that the film industry uses is horrible for fast panning shots and introduces limitations in the camera work, its an unfortunate truth of modern day filming when you consider that 24fps filming was a compromise between smoothness of motion and the cost of film its limitations are obvious, to discribe it as smooth is a joke...

...its just a compromise that became an industry standard, nothing more. Atleast a TV that can show 24p as it was originally shot can avoid introducing anymore judder then is already there.

ya sure, tell that to the backgound that likes to warp by when the camera follows the actor walking across the scene...


24p can be made smoother by elevating the level of blur...

fix't

anyway

Most TVs with motion-smoothing tech (that converts low-motion to high-motion) have an option to select the level of processing.

Usually, low is the best option. It will retain the 'film look' while making it appear tad smoother. Mid and high on the other hand can induce soapopera effect, which most people hate.
