Strange title, i know... but after many drinks last night, and not getting in till 7, im a little "off"

Anyway, i have some video footage that will be going onto the PC within the next few days, which i have just watched on through the TV... Anyway, the video is just fine, but it looks a little too sharp, or it could be described as "Light snow effect" it's not really a BIG problem, but when i edit it, and slap some effects in, it is going to look a little poor quality...

Is there any software that exists to remove this kind of thing?

Any suggestions are welccome.
