Mild Pixelation on HD movies. Irritating! - Overclock.net

Truth · 2 Weeks Ago

I just upgraded my operating system to Windows 7 (See PC specs below) and I was going to watch another one of my high definition movies. Some of them are 720p and others are 1080p. Regardless, when I view them, there appears to be mild but highly irritating pixelation. The only reason it bothers me so much is because it wasn't like this before! I tried updating the drivers on my Radeon HD 4870 but nothing was resolved.

I even played with several of the settings in my VLC media player and nothing would rectify this issue. It's highly annoying and seems to happen only when I set it to full screen, despite the fact that it did not do this before when I had set it to full screen (Usually with an aspect ratio of 16:9 or 16:10)

Help would be greatly appreciated to rid me of this annoyance.

Does this only happen in videos that have a resolution of 720 and above? Does it happen with other applications, such as Windows Media Player or Quicktime?

How about removing all codec packs and installing just KMPlayer and see if the problem persists.Be sure to restart the PC after removing any codec packs.

PS: This happened with mkv playback right?

It's VLC. The renderer you're using is using point resizing which makes tiny blocks.

Find the video renderer setting and try all of them until you find one where black is not gray and there's no pixelation. There should be one.

What's the resolution of your monitor? And finally, where's the screenshot? :P

I cannot find this "renderer" you speak of.

Resolution = 1920x1080

EDIT: You can't see it very well in that image but it's there. Like I said, it's small but amazingly annoying. It should be smooth like it used to be.

Off topic:

Nice! Resident Evil CG Movie

It was pretty cool

I also get the same problems, but I was able to fix it by changing the Video Render to DirectX9, although that was done in Media Player Classic Home Cinema.

Hi, i used this guide and my cpu never moves as its all gpu proccessed, can't help with your problem , just thought i'd share the link with you so you could try a different approach

Page 3 is where it all really starts

So what we'll do is this, I'll show you what you need to have installed in your PC, how to set everything up and then enjoy the fruits of benefit with this intriguing Media Player Classic HT software.

Minimum System recommendations

Depending on what you plan to do with your home theater based PC, the requirements can differ. If you can live with the GUI and will stick towards Media Player Classic, you won't need much of a PC at all.

We tested this software even on an NVIDIA ION mini-PC with Atom 230 processor and x.264 DXVA acceleration wise it works fine. To be a little future proof we do recommend the minimum hardware level to be a tad higher:

For graphics processing we need:

nVidia series 8*, (9)xxx and GTX or newer.
ATI Radeon HD series 3000 and 4000 or newer.
* some older models 8800 cards have the older VP1 (video processing) engine, the updated NVIDIA VP2 asic can decode bitstreams which is what we are after. Examples of VP1 would be 8800 GTS 320 and 640 MB. You will still be able to decode content, yet partly. The 8800 GTS 512MB en newer cards have the new VP2 engine, which will be 100% supported.

Let me show you some cheap examples of what would be very sufficient as a HTPC, if you wan to use MPC HT software.

Example AMD based HTPC:

AMD Athlon 64 X2 4800+ Dual Core Processor (45 USD)
2 GB Dual channel memory 667 MHz or higher (30 USD)
AMD 780 GX Chipset based motherboard (70 USD)
As you can see the above example is a 150 USD configuration has an integrated Radeon chipset that works really well with Media player Classis when it comes to x.264 acceleration. However, if you like to run shaders like Image sharpening, we recommend a dedicated graphics card.

A passive NVIDIA GeForce 9500 GT or Radeon 4650 would be very sufficient to handle additional image processing.

Example Intel based HTPC:

Intel CORE2 Duo Processor E5200 (72 USD)
2 GB Dual channel memory 667 MHz or higher (30 USD)
nForce 730 / GF9300 chipset based motherboard 120 (USD)
As you can see, an Intel configuration immediately boosts price a little. We end up spending roughly 220 USD for roughly the same features as the AMD offers. Again, if you like to run shader like Image sharpening, we recommend a dedicated graphics card. A passive NVIDIA GeForce 9500 GT or Radeon 4650 would be more than enough to handle the additional image processing.

These examples are of course the lowest range, cheapest products to build a HTPC. Anything faster is recommended. But the gear mentioned above, will manage 1080P x.264 content, accelerated by Media Player Classic Home Cinema perfectly.

Now your question would be, what components would you use if you had some more cash to spend. Personally I'd opt an AMD 790 GX/FX based motherboard, 2 GB DDR 800 MHz and Phenom X3 720 processor (review here). Massive value for money. I would insert a dedicated graphics card though, just to be sure I could enable complex shader algorithms to enhance image quality. Something as simple as a Radeon 4650 or GeForce 9600 GT is fine really, but faster and newer is always better. The clock frequency on these products (important for the video processors) are high enough to process data + they have enough shader processors for post processing.

Software Requirements

What do we need to do:

Download Media Player Classic Home Cinema (GPU accelerated) - click here.
Download and install the latest Direct X - click here
Make sure your graphics card drivers are up-to date.
Make sure you have a nice collection of x.264 / MKV content. Lots of trailers can be download on the web.
Windows XP or Windows Vista ?

Both operating systems work fine with Media Player Classic Home Cinema. We included both the 32-bit and 64-bit versions in our download. We do however feel that Windows Vista is the better OS to opt, it's also the OS we'll test on. In the MPC software we'll have to specifically setup the software in order to support either Windows XP or Vista.

Windows XP users, select Overlay Mixer, VMR7, VMR9 or VMR9 renderless
Vista users, select EVR or EVR custom renderer
But let's walk through the software setup, next page please.

Still need help with this problem. :P

(Don't know where to find the video renderer setting on VLC.

Coma · 1 Week Ago

You can just not use VLC. Post a full-size screenshot.

The video renderer is now called Output under the Video tab.

Just upgrade to CCCP + MPC instead of fiddling around with a subpar player.
