with "crop black bars" enabled:
720x480 -> 719x360 (21:9)

I don't think I can make it any clearer than that in the limited space the OSD has available.
Here are a couple screenshots with various settings. I'm just wondering why the DAR is changing from 16:9 to 21:9.

Good to hear!

Haha, yes, good point...

No.

Please use "Aspect Ratio -> Fit to Video" and not "Fit to Window". Using "Fit to Window" often destroys the correct aspect ratio. The black bar detection stuff makes much more sense if you use "Fit to Video", as you're supposed to.

I couldn't find this setting using MPC-BE.

Ah sorry, my fault. In that case use "Video Frame -> Touch Window From Inside". Do *not* use "Stretch To Window". Same thing as in my previous post, just other names.

Oh, that's surprising. And that is with madVR v0.89.11? Which MPC-BE version are you using? Can you create a debug log for me, and maybe upload a small sample of that video file?

I am using madVR v0.89.11 and MPC-BE v1.4.6.892. I'm not sure how to cut a small sample but it happens with all of my DVDs. Here is a debug log.

Another thing that really interest me is to understand the "real" difference between xbr-100 and 150, I could not find any comparison but just people preferring one or the other but without a real explanation of the reason.
Guys any comments on this?

Madshi,

Do you have any idea on how madvr would fair with Nvidia Quadro M6000?

I found that enabling it in JRiver Media Center really messes things up when videos contain multiple aspect ratios.

For example, I have a video which is supposed to be displayed as 16:9, but it is horizontally compressed.
This video contains three different aspect ratios:
  • 16:9 full-screen
  • 4:3 pillarboxed (12:9)
  • 16:9 windowboxed (16:9 letterboxed in a 4:3 frame)

Because it is horizontally compressed, it actually displays as approximately:
  • 15:9 full-screen
  • 11:9 pillarboxed
  • 15:9 windowboxed (15:9 letterboxed in an 11:9 frame)

If I enable aspect ratio correction in JRMC what happens is that you get:
  • 15:9 full-screen → 16:9 full-screen (correct)
  • 11:9 pillarboxed → stretched to 16:9 full-screen (very wrong!)
  • 15:9 windowboxed → 16:9 full-screen (correct)

The current best solution is to forgo the aspect ratio correction and have Zoom Control handle the windowboxed image:
  • 15:9 full-screen → 15:9 full-screen
  • 11:9 pillarboxed → 11:9 pillarboxed
  • 15:9 windowboxed → 15:9 full-screen
This is wrong, but not disastrously wrong.

It will just work like it's GeForce counter part, madvr don't get any benefit from huge Vram or pro card features.

Does SuperRes do any deblocking? Trying to figure out what it does exactly.

The only thing missing from madVR at this point is a deblocking filter. MPEG-2 DVDs look horrible when upscaled.

Can someone please tell the best setting for watching anime in 720p and 1080p for a high-end PC. I never watch anything below that.

@nijiko, if you have total PC freezes with v0.89.11, I'd recommend to start with test build 5 and work your way up to build 1, because build 5 is nearest to v0.89.9. So if you have no problems with v0.89.9, test build 5 is the most likely to still work ok, and the risk of getting problems is getting higher, as you get nearer to test build 1.
OK, when I have time, I'll test it immed. THX

Alright. DXVA outputs decoding results as "IDirect3DSurface9". madVR uses pixel shaders to do video processing, but pixel shaders can't access "IDirect3DSurface9". So madVR has to do lossy conversions to make the "IDirect3DSurface9" accessible for pixel shaders. This problem does not occur when using copyback or software decoding, because madVR has the pixels in CPU RAM then and can upload them to the GPU in a format pixel shaders can work with. Now don't ask me why Microsoft had the glorious idea to have DXVA output data in a format the pixel shaders can't process. You'd have to ask them, I can't really tell you that.
Is this also true for Intel QuickSync decoding?

And is this the case with all Nvidia GPUs, and with ATI/AMD as well?

quicksync is copyback only.

but the case where quicksync is a better choice than DXVA copyback is pretty rare.


and there is a simple solution to all theoretical DXVA native issue. it is called DXVA copyback.

But there IS image upscaling in this case, right?

Yes I got it, I meant there's not resolution upscaling... you got what I meant :-P

Any further comment on what I posted?

Anyway I've got another little doubt: when I play videos using MadVr I noticed that the CPU is not much involved, like 20% usage, is it normal? I know that lot of work is done by my GTX960 but the common idea is that MadVr needs good CPU...why if my old i3 is used only at 20%?

madVR doesn't really use the CPU.
