What you really want is probably turning on film mode / IVTC for this video? In that case use "deint=film" instead of the tags mentioned above. That should also make the display mode changer pick 1080p23 in your case.
Thanks. When I use "frameRate=23" no discernible change is made either, on the CTRL-J OSD I still see the original frame rate of the file. With that file in the log, I did want to do deinterlacing so deint=film does work. But with others, I want to just decimate, they're in 720/60p. I thought "frameRate=23" would have been the same as the old "23fps" option, which worked before for those, but "refresh=23" does work in that case.

Also, why not just leave the "refresh" tag instead of "refreshRate"? It doesn't really need fixing.

Such contents are very CPU computation intensive, especially on very high-bit-rated motion scenes.

My mini-server's C2D P8600 (1.6 ~ 2.4GHz) + dual-ch DDR3-1333 is not powerful enough to handle such material, either.

My HPTC is C2D E8400@3.6GHz + dual-ch DDR2-800. There is no problem for this CPU to deal with all Hi10 1080p24 contents.

Since H.264 Hi10 profile is not used in any industrial standard, I guess no graphics chipset vendor even considers to support such mode decoded with the GPU's video bitstream processor. So... Hi10p 1080p24~ needs a more powerful CPU --- at least Core2Duo 3 GHz performance level. (I guess)

I still would welcome a SD/HD threshold(as these days there are obviously far more WMV/XVID HD-to-SD 709 encodes around than upscaled PAL DVD's) but I've just been confirmed that the next build of PotP will advertize the first filename when opening a bunch of movies in seamless playback mode so at least tags will work

Hi,

I've tried to reset the settings using "restore default settings.bat" but nothing has changed.
I've looked in the registry to "HKEY_CURRENT_USER\Software\madshi\madVR" and there is only the key "LastSettingsKey".

How can I do the reset?

I'm using the Windows 7 x64.

Thanks

I found windowed overlay to be very annyong when moving player's window while in a DVD menu, it was unusable for some seconds after.

From another forum:
Quote:
Can someone posts this on doom9, I won't register there for single post:

madVR since 0.85.5 crops mod2 height video to nearest mod4 and resizes back to original resolution.
For example: 1920x866 crops to 1920x864 and stretches to 1920x866.

0.85.4 and older work fine. I tested it thoroughly in latest mpc-hc with LAV filters and also with ffdShow.

Correct | Wrong

With latest madvr and latest mpc-be auto play works again on extended display, thanks madshi if you fixed it.

ajp_anton: The bottom 2 lines are damaged of every mod2 video I've seen, avisynth problem I think, that one is no exception. It can be really annoying at times if you look for it. I'm glad madvr is cropping to mod4 but wish it wasn't stretching back.

DXVA2 resizing with a little edge enhancement is very pleasing to my eyes, even if it is just bilinear with post-unsharp. I wonder what the more sophisticated resizers would look like with a post-unsharp.

Addition to the above, after I asked about scaler algo:
Quote:
I tried Jinc 3 taps and Spline 3 taps both with and without anti-ringing filter, but it didn't change anything.

Add:
That 2px dirty line on the bottom isn't dirty all the time and it's already in the source. I've done 1920x818 encodes which don't have any dirty lines.

Tested it also on another movie (1920x818) which doesn't have any dirty lines, same behaviour (crops bottom 2px and resizes back).
edit to turbojet:
I don't want madVR to crop it. It shouldn't try to protect the user from bad encodes, it's the encoder's job to do the job right in the first place. Even if h.264 somehow inherently sucked at mod2 (which it doesn't) and a codec-based fix is needed, that would be the job of the decoder.

I suggest to give the chance to adjust color and a transparency of panels Exclusive mode.

I spoke too soon about auto play working again with latest madvr+mpc-be, it only works when player is opened on primary display then moved to extended display when it used to pause. If player is open open extended display it starts paused every time still. Madshi can you let me know if it's madvr or mpc-be's issue to fix?

While I agree it really isn't the video renderer's responsibility to fix badly encoded files but it does the job currently, same could be said for colormatrix issues. I found out it's x264 to blame for the damaged lines when height is not mod4 and reported it.

Thank you, madshi for implementing the custom pixel shader trade-offs!

On my laptop the result is:
1. doesn't make a difference if it's on or not: store custom shader results in 16bit...
2. the other is making the difference: run custom shaders in video level...
3. "don't use copyback for DXVA decodeing" causes bigger GPU usage if it's enabled !!!
(using LAV dxva native) GPU:62%/69% , VPU: 23%/27% !!! , MCU: 42%/50%
And when I enable it on the fly it results constant green picture (it works fine in the opposite way).

Edit: tested with the v306.97, now I realised that a newer whql is out, I will test them again ...
Edit2: situation is the same with the new v310.70 driver.

I honestly don't think my eyes are deceiving me, overlay looks to be smoothest option.
I don't have dropped frames without overlay, possible or placebo? Each time I look at overlay I can see it, like it's rendered to the screen ever so slightly faster.

quality 'first

v0.85.5:

* up to 56% speed improvement for Jinc3 chroma upscaling
* up to 40% speed improvement for Jinc3 AR chroma upscaling

Madshi you are a genius, I was buying a new video card and suddenly my 6670 is powerful enough, but..........What did you done? A pact with the ? Are you sure there is the same quality in this Jinc3 than before? I have a bad feeling about this and jinc3 works too good to be ruined by compromise.

Good year, Fabio

By hard-coding certain parameters, you can easily speed up algorithms, i have no doubt that its still at 100% quality.
Of course these optimizations only work for certain special cases, in this case a clear 2x scaling, which chroma typically is.

Surely 2x is rarely used for luma. Chroma 2x is obviously very useful for 1080p content on a 1080p screen but no-one has any 960x540 videos, do they? I guess those with 2560x1440 screens playing 720p content would count but if you have screens that size, surely your content would be mostly 1080p.

In any case, Jinc for chroma with 2x scaling still isn't fast enough on my HD4000 (playing a 1080i/25 file on a 1080p screen).

Doesn't madVR first scale chroma to luma resolution, so it would be useful for all 4:2:0 content, regardless of display resolution/video resolution?

I wonder if upscaling to 2x by Jinc3 and then downscaling to 1.9x by Bicubic (or any other 2-tap stuffs, or even Bilinear) would be faster than directly upscaling to 1.9x by Jinc3 or not since 0.85.5. If it's significantly faster, it might probably worth a try even if there is a tiny quality loss.

Yeah I was recently wondering the same stuff as this was discussed ages ago and 16/9 1440*1080 stuff is really a GPU hog here, but I'm quite sure that madshi wouldn't force double scaling anyway.

All this said I've got the automatic PS gamut mapping profiling stuff working in PotP(and also 4:3 AR for 720*576 movies) and I'm always stunned by how good the AVS script looks, getting accurate colors really seems to increase the subjective CR.....that's what struck me when I first tried it on a "Mitsubishi HC3100" ages ago and it's just as apparent on my CRT...mix it w/ the killer 24p smoothness of mVR + Reclock and movies just look so true to life

There's only one last slight bug in PotP's automatic rules that would need to be ironed out but I guess I'm slowly running out of excuses to not ordering the BenQ W1070 at this point

I also see refurbished HD5870's being sold for 80€(w/ a 1y warranty), and that's quite tempting as it would appear to be almost as fast as the GTX660. I know that Jinc3 AR looks AMAZING, but tossing 200€ on a board that will be worth 30€ 2 years from now makes me feel conned

OTOH, I wanted to play around with 1080i@59.94fps and that'd be a no-go on the 5870's apparently..
