Different Contrast Ratio in WMPC Vs VLC and WMP also blocky

x_rex30 · Post by **x_rex30** » Wed Jul 16, 2008 7:03 pm

When I tried playing an mp4 or DVD in WMPC, the brightness seemed higher. When I captured a dark area that was suppose to be completely black and opened it up in Photoshop, it shows the black to be this..

When I capture the same scene from VLC or WMP11 it shows up like this..

Also when I play mp4s and movies in Windows Media Player Classic and VLC(blacks are fine in VLC), the footage gets blocky if I make it full screen, at least that's when I notice it.

Here's an example

In Windows Media Player 11 full screen it looks fine

Now here in WMPC Full Screen it's blocky.

See the blocks on the top of the guys head in the middle around the corners?

Now I was trying to fix the blocks in Avisynth then realized that it's not suppose to be there.

Any idea how to fix this?

Also if increase the size whatsoever in Virtualdub, the edges around characters get messed up.. I guess that's normal but not good for editing. This isn't as important to find out about so don't worry about this unless you have a good idea about it.

So mainly I want to see what's up with WMPC and VLC and if I can fix it. If you could help me out with that mainly that would be great.

It depends on a few things...

1) decompresser:

VLC uses an internal system for decoding video so you don't have to have the codecs installed on your system

MPC and WMP use what's installed. You can have multiple codecs that'll decode the same thing.

2) video rendering

There are different ways to render video. In MPC go to option and then Output and you'll see a bunch of different render methods.

I think this is a #2 issue so try playing with that. depending on your video card you should be able to configure video overlay through it's driver's control panel. from there you can tweak the settings so they look right.

Wow, second time in two days that you are there the second I'm asking for help!

I'll mess around with those settings and see what happens.

Thanks for the help again!

Haali's Video Renderer seems to fix the mp4s but causes dvds to stop loading... I'll keep messing around with the settings.

OK, I guess VRM9 renderless is the ticket.

I think I'll research every single one of these so I can make the best choice. I guess that's about it, thanks for the help. If you or anyone thinks they have something to add please do. Otherwise it seems I'm getting everything to work just fine except VLC. Thanks Pwolf!

I just found it it fixes problems but adds problems too.

On fast moving scenes now you see lines going through the screen(forget what you call this)

It's not something I can take a screenshot of, it only shows up during movement. When I put the settings back to VMR7 Then this problems goes away, but then the blacks get all messed up again... argh! Well... guess I'll keep messing with things.

Any tips?

Think it's called Screen tearing. I find it happens in WMP11 as well.

Oh well, this is a whole different issue then.. I think I saw this in games I played as well.. Nvmnd then I'll do my own research on the issue. Thanks anyways.

sure it's not interlacing?

screen tearing is due to the refresh rate of you monitor.

I've read just a sec ago there are things you can do to fix this. I'm finding out I might need to adjust settings in NVIDIA

And no it's not interlaced at all, it's progressive and things only have issues at fast parts.

Maybe it could be called display flicker? Well, I'm sure I'll find out all I need to know with some research.
