youre awesome. thanks!WESTNINE9 said:It's not bad...
120Hz is the best though.
A TV operating at 60Hz refreshes its image 60 times per second and it can display 60 unique images per second.
Most film is/was shot using 24 frames per second whereas video is shot using 30 or 60 frames per second.
For the video it's no problem displaying it smoothly on a TV that operates at 60Hz because the number of video frames divide evenly into the TV's refresh rate.
If the video you're displaying has 30 frames per second your TV will simply display each frame twice.
But if your source is film with 24 frames per second you can't directly map the film frames to the display frames evenly.
To get around this they use a technique called 3:2 pull down.
3:2 pull down is an algorithm that displays some of the frames 3 times and some of them twice in order to map the film's 24 fps to 30 fps.
The downside of 3:2 pull down is that it introduces motion artifacts.
This is mostly noticeable in fast moving scenes or pans and you may see blurriness and choppiness.
This is where 120Hz refresh rates come in.
120Hz is the best right now because 24 fps film or 30 or 60 fps video all divide evenly into the refresh rate of the display so you sont need to use 3:2 pull down.
In a nutshell: 24(fps), 30(fps), and 60(fps) all divide evenly from 120.
