Spot teh COMPRESSION ARTIFACT...

Most any n00b who hasn't watched quality digital video for some time will open up a 640x480 128kbps video stream and say "Wow that's DVD quality".
Maybe you also notice that maybe your AMVs and media files look better on Media Player, though it takes up a LOT of ram and processor time.
It's not amazing, it's a trick!!!

It's sort of a secret...

Windows Media Player adds a Sharpen algorithm to your video!
(and also a special algorithm to your sound too)

First box: Actual full frame data
Red outline means this is the data highlighted

Box underneath: Smart resize to 2500%
Box inside: Regular resize to 1000%

The fuzzy stuff, anybody knows, is crappy looking. But why doesn't it look pixelated, it is OMG cheap trick!

On by default.

You might want to know that it's hacking your sound up:

Are you using RealOne? They do that too:
Equalizer says "Clear" on start XD.

How does that img prove that there's some kind of filtering? By the way, media players themselves don't do any postprocessing, only the decoders.

Hey,

Umm... You're retarded. If you took ANYTHING, even a retail DVD, blew the image up with a nearest neigbour resize filter to about 1000% it'd look all pixily like that too.

Here we have a DVD image, this is a direct frame capture, WMP was not involved in ANYWAY. I then selected a section and blew it up with a bi-cubic filter and then with a nearest neighbour filter.

You may notice that it looks like crap. Why does it look like crap? BECAUSE IT WAS RESIZED USING NEAREST NEIGBOUR!

I wonder if Phade realizes just what he's started here.

That image shows the post processing. The tiny patch is the work sample... if you blow it up in WMP, it is antialiased automatically. The other box shows the pixels.

There. It DOES postprocess your video and mess it up.

Anti-aliasing and resize filters are completly different things. -.-;;

There's othser resize algorithms than nearest neighbor, btw.

Some Zancos resize or something. I think it's in AVI-Synth.
