The Hardware Acceleration your card supports is only motion compensation if you're talking about H264 videos and it's hard to implement such feature in MPC HC.

While the above answer was dated since September...

I get it. So, what do you suggest?



From the old and unofficial MPC help:

Use regular offscreen plain surfaces - video surface is treated as usual surface outside the screen.
Use texture surfaces and render video in 2d - video surface is a texture, for copying and stretching uses 2D functions. Requires a videocard which supports 32bit RGBA textures with sizes which are not 2 multipliers at least with video resolution.
Use texture surfaces and render video in 3d - video surface is a texture which consists of two triangles in 3D. Antialiasing can dramatically slow down rendering process.
Resizing - in 3D mode you MPC can use different filters when scaling the image. The most simple and fast is Nearest Neighbor but it gives the worst quality. Bilinear is quite quick and gives good quality, there is variant which uses pixel shaders. Bicubic method has the best quality, but for realtime image processing requires powerful enough video card. There are three variants of bicubic interpolation, the difference is sharpness level (0,6 - the most sharp one).

BTW, the artifact lines when using EVR Custom with Bilinear or Bicubic PS 2.0 resizer are fixed in the latest MPC HC. I'm only mentioning this because earlier posts of this thread come up in Google search when you're looking for info on EVR vs. EVR custom, so i thought i'd mention it for those people.

Concerning the different resizers, the Bicubic ones have the best quality for me. Sharper than normal EVR and EVR Custom Bilinear.
Thanks.

Hi people!

I have a problem with DXVA.

Link: http://www.sendspace.com/file/gfihhl

Watch original_sample.avi first, then stutter_sample.avi (this is what I see).

As I see it, x264 doesn't do well with the avi container in dxva (mode or whatever it's called).
I know that you shouldn't use avi for x264.

Even if I extract the raws and put it in mkv it doesn't help.

And if you look at sample_filters.png you can see that I use EVR Custom, and that is when the stuttering appears.
If I use system default the problem goes away (dxva isn't in use).

The sample is from [Nya] Osen Ep. 6 (1280x720) (it's a japanese tv-series).

Sorry about the ranting but I hope someone can give me an answer to why this is happening maybe and/or a solution
It's greatly appreciated!

[QUOTE=Aleksoid1978;1217279]i try :

Resizer - use Bicubic A=-1.00 (PS 2.0), better resize quality;

are these settings the same as for haali video renderer for sharpness?

Couple of small problems with an otherwise brilliant media player

(i) I have been unable to play any .flac files for a while with various svn of MPC-HC, I just get "cannot render the file". It is possible I changed a setting that has broken it but I don't know what so I'd appreciate a tip to fix this as it is just about the only filetype that doesn't work.

also (ii) if I associate a filetype handled by haali splitter in MPC-HC options it seems to break haali thumbnail extraction for videos- is there a way to get round this- does MPC-HC have a thumbnail extraction ability or one in development?

Sorry to ask the obvious, but you do have a decoder installed, like madflac?

About 50% of the time, whenever I drag/drop a .m2ts (1080p AVC) file into MPC-HC (x64 r906) while a file is playing, MPC-HC crashes with a C++ Runtime error.

Edit: Another bug. With DXVA enabled, one of my 1080p AVC .m2ts files is decoded incorrectly but ffdshow displays it just fine. (Hard to get a frame accurate comparison because MPC-HC is also blending a previous frame.)
I can upload a sample if needed.

I find that when A=-1.00, the picture looks to be over-sharpened. Try A=-0.60 then go up from there.

because i read that -0.6 is the sharpest and -1.0 is the softest in haali video renderer. but i don't know where and can't find it again.

i think we should have an option to select the number instead of having just -0.60, -0.75 and -1.0

The file association code is probably deleting the shell extension registry keys that are created by Haali.

Thumbnail extraction is done by shell plugins for Explorer. That is totally unrelated to players.

Hum... I checked for myself and "-1.00" is the most soft as possible for haali and "-0.00" (haali goes from "-0.00" to "-1.00") is the most sharp.

Seems that haali uses the settings in reverse from EVR (that goes from "-0.60" to "-1.00", soft to sharp)

Your statement was corret.

Good point... thanks I thought mpc-hc might have a built in flac decoder like vlc, installed madflac now all works OK.

Thanks for your reply. So is it possible to have mpc-hc associated with video files and still have thumbnail extraction- do I need a separate plugin to enable that- if so can anyone recommend one (for XP)?

Any idea why the Standalone Filter fails rendering on NULL within timecodec ?
