Hi guys,
I've just made a quick'n'dirty comparison between VP8 and x264 here:

have a look and tell me what you think!
Cheers,

I watch blu-ray
I don't know what this adds to the discussion, but I'm just used to having completely uncompressed video and audio.
blu-ray is sexy Mmmmm....
Oh the first Avatar blu-ray that doesn't have any special features, but just the movie (and copy of it on DVD which is nice) is supposedly completely uncompressed. The other versions will apparently be compressed. Don't quote me on that though, I just got that info from media/audio buffs.
Have you noticed that on some blu-rays there's that grainy effect if you look really close at you TV? Avatar didn't have that though. I would understand it on the blu-ray versions of old movies, but I've seen it on some of the newer movies as well.
Well let's do simple math to compute the uncompressed movie size:
(2 hrs 25 FPS) 2*60*60*25
(full HD) 1920*1080
(YCbCr 4:2:2) 2 (bytes per pixel)
= 746496000000 bytes
Let's say we achieve a lossless compression of 75% the total becomes
173.80 GB
Is a BD able to hold such amount of data?
Yes indeed, I think this happens when they don't film in digital.Have you noticed that on some blu-rays there's that grainy effect if you look really close at you TV? Avatar didn't have that though.

Quite impressive, I wish the images were a bit bigger so it would be easier to show case the visual quality as well as perhaps a torrent of the files produced. After all pictures is one thing, motion another and often one prone to cause nasty visuals.
