I didnt know where to post, this place seemed appropriate.

Does anyone have any good links or guides
of what YUV, Spatial, and Temporal workings are?

I know that a pixel has to have color and brightness and ?
and how is that pixel and or information represented in bits?

Confused =(

Thanks

YUV is another colorspace - that means another way of storing image information.
In contrast to RGB, it has brightness and color separated, Y being the brightness (luma) and U and V being the color (chroma).

You can use greyscale() to only se Y (luma) and you can use UToY() and VToY() in AviSynth 2.5 to see how colors are represented.

The specific format used by MPEG is also known as YCbCr some places on the net.

Spatial: This is used to describe, that a filter operates across pixels in a single frame. Spatial processing is not dependant on the previous or the next frame.

Temporal: "Processing in time". A temporal filter uses information from the previous and the next frames to construct the current frame.
