When watching the blu ray movie "Speed" on my PS3 why do I spot alot of static or as they call it film grain

Question

I have it running 1080p through my LCD tv which supports that resolution, and it's going through the HDMI cord, so why all the film grain?

Answer 1

The film grain has been there all along -- you just can't see it very often with low-res TV.

It's possible that your LCD TV can't handle the amount of motion in the movie ("Speed" has lots of that), and that you're seeing HDTV decompression or LCD response-time artifacts. If the TV's video processor isn't fast enough to fully decompress the HDTV data, you might see data blocks that aren't fully decompressed which, when they are finally corrected, could appear to be "noisy." The LCD itself isn't very fast when it comes to changing intensity, so if the scene changes rapidly, it could add to the problems.

Too bad the PS3 doesn't have component video outputs so you could let all of that processing horsepower do all of the hard work and let the LCD just display what it gets...
