Stutter playing 1080p, Blu-Ray - Page 2 - Overclock.net

@Space Ape

If you didn't have any REP+ I would've sworn that was a SPAM add, will give it a try.

Thanks guys.
I'll try a few things and see what happens.

Tried those, looks exactly the same and still stutters...

CPU usage is still around 45-55% which seems normal to me, not too high.

If this doesnt work then i believe powerdvd also is good at decoding
HD.

My 8800GTX has the G80 COre, will that be a problem?

I have PowerDVD but it keeps crashing, I'll try it again.

yes perhaps m8. i would still uninstall all decoding software (playing sw) and then try what i proposed again.

remember to update all your drivers to the latest versions.

hmm as a lasr resort i would reinstall the operating system.

There's just so much wrong with this post.

Yes, it uses MPC's internal VobSub, so DirectVobSub doesn't load... A stock CCCP install won't load DirectVobSub. If it does, you should reinstall CCCP and tick "reset all settings' during install.

I have no idea why you'd want to do this.

Step 2. Now go to output and pick WMR7 (windowed)/WMR9 (windowed) for xp and “EVR Custom Pres.” for Vista/Win7. Set EVR buffer at the lowest value.

No. VMR is horrible. EVR works properly (I think, never tried), but you should just use Haali's Renderer in all cases, since it's guaranteed to work and it uses the GPU to do the rendering (your GPU must support Shader Model 2 for it to work).

Quote:

Step 3. Next go to Internal Filters. Make sure that under ”Source Filters” ”Matroska”, ”Ogg” og ”MP4/MOV” is unchecked. Under ”Transform Filters” make sure that ”H264/AVC (DXVA)” and ”H264/AVC (FFmpeg)” is checked.

Why?
1. CCCP comes configured already. You shouldn't modify that.
2. Enabling H.264 decoding with both DXVA and FFmpeg is unnecessary. Enable only DXVA. When it's available, MPC-HC will use DXVA, otherwise it will fall back to DirectShow (CCCP's ffdshow).

I don't like DXVA though since it forces using the Overlay Renderer which on some computers doesn't adjust levels, which makes everything looks washed out.

Quote:

Step 4. in this last step we most make sure that there isnt any filters
conflicting with DXVA. Go to ”External Filters” here click the ”Add Filter” button. choose ”ffdshow Video Decoder”

And block it.

Again, unnecessary. You've already overridden it by enabling the built-in filter.

Quote:

Done! now the way you test that it's working is by..Open an HD video.
Rightclick on the videoscreen as shown below. Pick ”Filter” then ”MPC Video Decoder”.

If it looks like on the picture you're running DXVA acceleration.

Yeah. This is probably the only thing this guide did right.

Picture enhancement:

Step 1. Again rightclick on the filmscreen. Click "Shaders" -> "Combine Shaders".

Step2. Add 16-235 -> 0-255, sharpen complex & deinterlace (blend).

16-235 -> 0-255: Your renderer should be doing this. If you do it manually too, the blacks will be crushed and the whites will be blown. You'll end up with something like this: renderer only, renderer AND manual.

At first look it may seem to be better, but it's not the way it was meant to be viewed. If you compare the "renderer only" version to the original, before the renderer did its own stretching, it would look "better" too, except with no detail loss.

You can see lots of detail was lost in dark and bright areas. You're pretty much doing this:

to:

Sharpening: You really shouldn't - especially when it's a Blu-ray. It looks exactly the way it was meant to look, and you shouldn't change it. If you sharpen, why stop there? Start playing with the hue so red is yellow. It might look better for you, but it won't look the way it was meant to look.

Deinterlacing: Just downright stupid. 99% of Blu-rays aren't interlaced, and the 1% that's left are telecined - which means you should *not* deinterlace, but perform inverse telecine. Deinterlacing will reduce quality significantly.

Hope this works for you mate

Edit: Just found the guide in english..not the danish that i've translated from
maybe more understandable:

This guide is horrible, stupid and misinformed. Don't follow it.

Instead, just install CCCP (you can install the beta I guess, though it doesn't really matter). The installer should ask you if you want to open the CCCP Settings window. Check that option so it opens. If it doesn't ask you, you can open it after installing by going to Start -> All Programs -> Combined Community Codec Pack -> Settings.

Make sure the General Settings "tab" looks like this, and press Apply:

It'll ask you if you're sure, so click OK.

You should be good to go now. If it still happens, press View -> Statistics in MPC-HC and check the Frames line. Play through that scene, and make sure it stays dropped: 0.

If it changes, then I'll continue from there. If it doesn't drop any frames, then write down timestamps for that scene - when it begins and when it ends in that specific MTS, and I'll show you how to cut just that scene out (without encoding it, takes seconds) so I can have a look.

G80s can't do full H.264/VC-1 bitstream decoding, so you can't use DXVA.

Relax dude i didn't make the guide only posted it

Good thing you can set the record staight then mate

@Coma

Will get onto that ASAP, thank you.

UNinstall ANY codec packs, use the Media Player Classic Home Cinema. It sports one of the fastest decoders around.

If it doesn't help, download the CUDA driver and get CoreAVC.
