Need help on graphics cards.. (buying)

[SE14man]

Hi,

I was wondering what the best cards out there at the moment for handling very high definition video:

For example .mkv files at 1080 H264?

If i play it now it's very jumpy and extremely pixelated (blocky) does not function properly. When played on WMP it does play but very jumpy and very 'liney' interlaced i htink is the word!

Can anyone tell me what sort of hardware i'd be needing to look at in order to resolve these problems? Is it not only a graphics card i'd be needing?

Thanks very much.

Have you tried play with MPCHC and see if you current card supports dxva h264 hardware acceleration ?

Pretty much all cards that cost over US$50 support hardware h.264 decoding these days. Not all h.264 features are supported by any card though. So you need to have at least a dual core CPU as a backup (and a multithreaded software h.264 decoder like CoreAVC Pro, ffdshowmt, MPCHC).

Also be sure to use the appropriate video output device and enable deinterlacing in the output device or the the graphics card's setup applet.

Hi there,

I have a Geforce 8500 GT graphics card and i'm not sure if it supports H264.

What's VLC like at handling H264? Is it still dependent on what graphics card you have?

If i were to get a good Graphics card would this stop all the jumping in video playback? Or would i still have to go adjusting everything in ffdshow?

My PC specs are: Intel Core 2 Duo E4500 @ 2.20 Ghz. 2 GB RAM

Is this good or would this be another reason why playing 10 GB HD files would be making it jumpy??

Cheers.

I'm pretty sure the 8500 GT is the lowest of the Nvidia cards that has h.264 decoding.

VLC has a single threaded h.264 decoder and it cannot use DXVA -- the Windows interface that allows for h.264 decoding by the graphics card. So it is a poor player for HD video. Try using MPCHC. Be sure it's h.264 decoders are enabled:

View -> Options -> Internal Filters... In the Transform Filters box enable H264/AVC (DXVA) and H264/AVC Ffmpeg. Double click on the latter and set the Decoding Thread Number to 2. Exit and restart MPCHC for the changes to take effect.

When playing the video you can select Play -> Filters and see a list of the filters being used.

There are some other settings that can effect video playback. We can look into those if you continue to have problems.

Thats amazing i have noticed a HUGE improvement!

thank you very much.

It seems to be kncoking sound out of sync after playing it for about 1 minute... how would i go about sorting this out?

Cheers.

Ive been using the Nvidia 8500GT video cards and they've been working fine for me.

I did recently bump up to the 9800GT cards but that is so I can play Crysis ... with higher settings.

About your Nvidia 8500GT card ... it may not be what you think it is.

Do a search and get the free program ... GPU-Z.0.3.8 ... and use it to check your speed of the video card.

Some Nvidia 8500GT video cards ... are 64bit ... and some are 128 bit .... 128 bit ... being better.

If your mobo uses ... nvidia drivers ... you might want to think about getting the program from the Nvidia website ... NVIDIA System Tools with ESA Support ... version ... 6.05_nvidia_system_tools.exe

You can use it to over clock your Nvidia video card.

Hello there,

Excellent thanks for that.

Have run GPU-Z here are my results:

Does it need overclocking and if so is it hard?

What's the exact right tool i'd need to overclock it and how do i find out if my motherboard can accept Nvidia drivers?

Thank you.

Know what i mean?

[lacywest]

Know what i mean?

Your clock speed is good for that video card ... that is the same speed I see on mine.

If you use the Nvidia System tools program ... http://www.nvidia.com/object/nvidia_system_tools_6.05.html

The speed can be bump up to 705 MHZ ... it will also bump the shader clock and the memory clock ... just remember ... the memory chips on the graphic card will become more ... hotter ... might want to find some addon heatsinks that somehow can be attached to the memory chips to help keep them cool.
