I was told to post my question here.

Can anybody explain why does luma signal in composite video come out blurry compared to S-Video and component?

I know NTSC standard by default used reduced bandwidth for chroma, so it had pretty sharp BW picture with slightly blurred color layered onto it. But composite output seems to blur both chroma AND luma. What gives? In essence, it produced somewhat "downscaled" picture.

I was told that was because composite low-passed luma signal. But, wouldn't it mean it would simply cut out signal with lightness up certain point, resulting in dimmer picture?

Can anybody explain why does composite video blur everything so much?

I know NTSC standard by default used subsampling for color, so basically you had sharp BW picture, with slightly blurred color layered onto it. But composite output seems to blur both chroma AND luma. What gives? Basically, instead of 320 pixels horizontal resolution it displayed only 160, speaking of Genesis (albeit with more possible colors).

Also, speaking of Genesis, does anyone know what caused the infamous "rainbow" artifacts, e.g. like on tubes in Chemical Plant stage?
