I also tried to force 100% brightness(in order to defeat PWM) and counterbalance from the PC (as this guy did) but that didn't help at all.

I guess PC monitors makers have a lot to learn from those who make TV's huh....I previously tried a CCFL TV from Hitachi that made me see bright green RBE's but nothing more, even this cheapo TN TV didn't hurt my eyes at all: http://www.amazon.co.uk/dp/B00933LX5G

BenQ supposedly have a flicker-free monitor in the works, but I don't think I'll try it if it's like the BL2410PT at max brightness huh(and the contrast spec falls back from 5K:1 to 3K:1): http://www.benq.com/product/monitor/gw2760hs/

In order to remain OT, I would say that it's capped to 1080p@66.66Hz(due to the 165MHz pixel clock limitation of SL DVI, didn't have any DL DVI cable around) and FRC in mVR looked OK'ish, definitely not as smooth as 90Hz on a CRT though IMHO.

Apart from this, gamut and contrast were great, black was also the best I've seen on a LCD screen(even though it "glowed" and wasn't as solid as a CRT but it was really black!), the antiglare layer was a bit annoying due to its pearly appearance(the GW2760HS supposedly comes with a semi-glossy finish), the front panel buttons barely worked(thanks to a craptastic motion detection) and the pivot of the panel was a real pleasure to use. There was also a small round patch in the right bottom corner that looked slightly lighter on a light gray background, humm...I think the blue panel is FUBAR.

And anyway, all those PC monitors work internally in 8bit(and more often than not 6bit, as proven by their poor REC709 gamut coverage), that's really the stone age when all serious TV's work in 12bit and videoprojectors have been working in at least 10bit for over a decade.....oh well, someday I'll find a flat screen that'll make me happy, I'm a believer

It is not a decimal to do arithmetic with.
You can do 100 revisions with 1.01, 1.02, etc. How is that unreasonable? The other option of course is to use more than one decimal point; it's more obvious that 1.1.0 is larger than 1.0.2 than 1.10 being larger than 1.2.

madVR settings

I've created my own media center frontend using SDL 2.0 and use LAV filters with madVR. I create a native win32 window to host the renderer. This window is disabled and disallows focus to allow window events to be captured by the primary SDL window. When entering and leaving madVR fullscreen exclusive mode, the hosted window becomes enabled and focused, so keyboard and mouse events aren't being captured by SDL. The first time I change from windowed to exclusive, the hosted widow remains disabled, but any subsequent change back to windowed allows the renderer to be focused.

Would it be possible to add an option to keep the hosted window's styles when entering and leaving fullscreen exclusive mode? It would also be nice to see an option to fully disable keyboard shortcut processing in madVR. I'm sure most user's wouldn't need these options, but it would help my effort tremendously. The frontend is designed to use DirectShow, VLC, mplayer, mplayer2 and any additional player that supports embedding, but DirectShow is default for obvious quality reasons.

BTW, here's a sample of a levels range issue I've been encountering quite a bit lately: test.mkv (2.9 MB)

Here are some screenshots showing the problem.

Basically, the auto-detected TV range looks washed out and I have to use the PC range that looks OK, but apart from some randomly pesky video files, PC range usually looks lighter than TV range so I'm kinda confused here? FFDshow shows that there is indeed life <16 but then processing a PC>TV conversion should make it darker and not lighter

Oh well, I'm not too used to 0-255 native content, maybe that's expected behavior after all

Thanks for the feedback. Personally I'm a fan of CRT image and couldn't be happier with Sony FW900 as a monitor. It offers so much compared to LCDs. Even having a great projector (Mitsubishi HC5) there are times when I miss the image my FW900 can produce.

I am actually still using a GDM-C520 but it can take up to 5-10min to start it at the beginning of the day (I think the caps are drying out or something). Well it has lasted over 10 years so far... still waiting for something better to be invented.

With the newer scaling modes really pushing many gpus hard is there any plan to offer CUDA support in the future. This could allow us to possibly use more than one low end card and still use high quality scaling.

You still seem to be acting as if version numbers of arithmetic decimal numbers which it is not. The period is nothing but a delimiter between a major and minor version number. Also, adding a second period is usually signifying that the 3rd number is a bug fix number. So saying to use 1.0.2 instead of 1.2 doesn't really make any sense.

Think of it this way: When you type out numbers from, say, one to ten do you type 01, 02, 03, 04, etc. or do you type 1, 2, 3, 4? Each number delimited in the version number major.minor.bugfix (or whatever format used) is a distinct integer value of its own it is not a fractional number just because it's after a decimal.

End of derail.

With the new presentation path, the GPU driver is responsible for syncing to vsync, so it's the GPU driver which misses the vsync fliptime, not madVR. Doesn't make any difference to you, but I'm not taking the blame for NVidia bugs...

I'm slightly confused now. SmoothMotion FRC does not reduce 24/25p judder.

If copyback doesn't work, either, then it can't be madVR's fault. You may want to report this in the LAV thread. If copyback doesn't work, it's nevcairiel's job to fix this.

That sounds weird. Is this a new problem or did it always behave this way for you? If it's a new problem, does it only occur with specific MPC-HC builds? Or what else did you change recently which might have introduced this problem?

Well, you could switch your PC into 720p output mode and then let your TV upscale. Of course the end result will not be as nice as letting madVR do all the work, but if your GPU is so slow, you'll have to live with *some* compromise. You could also try all those "trade quality for performance" options in the madVR settings. Maybe some of those make a difference for you? But keep only those checked which you absolutely must.

gave me massive frame drops with smooth motion on. Then I said using FSE fixed it. But turned out I was wrong. It's when I zoom in the picture in MPC (hit Pan&Scan increase size about 8 times) that I get the frame drops with smooth motion on. Playing in unzoomed size or smooth motion off causes no problem. windowed/windowed overlay/FSE makes no difference.

Oddly, most stuff play fine. I don't know what's different with that video (and others).
I don't know, either, seems to work fine on my PC. You could try demuxing the video and audio tracks, and then mux the video to MKV with eac3to. Afterwards add the audio track back in with mkvtoolnix. This way you should get an MKV file with "optimal" timestamps. Maybe the timestamps in the original file are somewhat broken. This is just a wild guess, though...

Activating Lanczos/Jinc makes no difference if you don't actually scale.

I usually only update the first post when I release a new build. So the date is usually equal to the date of the latest version. Of course there's no guarantee, I might update the first post once in a while without posting a new build - but that's rather rare.

Anyway, why is the date so important? I would imagine the version number is the key and that's visible on the first post.

However, for the odd video file that I have, even if I tag it with [refreshRate=60], the display will still switch to 24hz because I don't have 1080p60 as a display mode in the settings. Is there a way you can make the filename tag override this and force the switch to whatever refreshRate is specified?
It's possible, of course, but it's not as easy as it might sound. E.g. if you use a tag [refreshRate=60] how would madVR know which resolution to switch to, if there's no such mode in the display mode changer list? This sounds like too much of a headache for me. Why don't you simply add 1080p60 to the list of supported modes?

But on Windows XP, after the upgrade any video I play with MadVR shows dropped frames for like 10-15 seconds, then plays normally and after a while dropped frames appear again for the same length. If I choose other renderers videos play normally. If I choose lower settings in Madvr, delay may appear much later or not at all if the video is lower in quality.
I'd suggest to check whether the GPU is clocking down when the frame drops occur. Try forcing the GPU clocks to a fixed value with one of those tweaker tools.

Other people reported that for SmoothMotion FRC to work correctly, they had to increase the queue size. Seems this is one of those things that is different for every user, depending on OS, GPU, driver etc. Maybe the higher queue makes problems for you because the GPU is running out of RAM? Don't know...

If you watch 1080p content on a 1080p display, madVR doesn't have to scale at all (except chroma), so that's a lot easier on the GPU. However, 720p content upscaled to 1080p should consume at least as much resources as 480p upscaled to 1080p, so I'm not sure what's going on there. Well, maybe the 720p content was 24fps and the 480p content might be DXVA deinterlaced to 60fps? Of course 60fps consumes 2.5x as much power as 24fps.

Sounds weird. Does your laptop use the NVidia GPU or the Intel GPU for rendering? Maybe it's one of those cases where the communication between Intel <-> NVidia GPU makes problems somehow, I don't know. If you don't have any problems with windowed mode, you can simply disable exclusive mode. Although for most people it should produce better performance than windowed mode! You could also try whether the "use a separate device for presentation" option helps or not.

I've had got set Chroma Upscaling to Jinc3 but have dropped to Spline3 which has reduced no. of instances of the buffer dropping to 0 - but not totally eliminated it

What is the difference between the content where the render buffer drops to 0 and that where it stays at 6+? Different framerate maybe? Or one interlaced, the other progressive, maybe? Are you using fullscreen exclusive mode? Maybe posting a screenshot of the debug OSD (Ctrl+J) when the rendering queue does to 0 might be helpful to diagnose the problem further...

Why is your present queue so small? Try using a *much* higher value, unless you're short on GPU RAM. E.g. try 12. Does the present queue then still go to 0-4/12?

If you have disabled the display mode switcher, madVR will simply use the desktop GPU mode. Whether madVR upscales or not depends on the settings of your media player. E.g. if the video is 480p and your desktop GPU mode is 1080p then madVR will upscale 480p to 1080p if you set your media player to e.g. "touch window from inside" and then switch it to fullscreen.

Im using software decoding on a i5 3337U CPU with HD 4000 and Radeon 8730m dGPU.
130ms render time is *A LOT*. Much too high for fluid playback. Maybe the 8730m is too slow, I don't know. Try starting with Bilinear scaling for both chroma and image scaling. If that works fluidly, you can try using more expensive scaling algorithms. Also make sure you don't force Antialiasing and Anisotropic Filtering on in the GPU control panel. These features have no benefit for video rendering, but consume a lot of power.

Any better recommendation for such material.
My main goal is to hide compression artifacts.
For hiding artifacts I'd suggest SoftCubic. Of course it'll be blurrier than other scalers. You could also try setting up some AviSynth noise/artifact reduction scripts, if his CPU is fast enough for that. Or alternatively some custom shaders (they're not as good in quality as better AviSynth scripts, though)...

Having it off might introduce tearing. If you don't have tearing with it turned off, then there should be no difference. Aero adds a little bit of additional GPU consumption, so performance with it off might be slightly better. Of course in fullscreen exclusive mode or when using Overlay, it doesn't matter whether Aero is on or off.

Not sure why you get 5x slower rendering in FSE mode. Makes no sense to me. You could try activating the "use a separate device for presentation" option. That helps some people, but I've heard it makes problems with some laptops with shared GPUs. Maybe it helps you, or maybe not. You could also try checking whether the AMD GPU clock goes down in exclusive mode for some weird reason. If it does, try to use a tweaker to fix it to a reasonably high clock.

It is possible that in exclusive mode your AMD renders the frame, then has to send it to the Intel GPU for output. Maybe that is so slow for some reason. But I don't really know...

You've made very clear that the nvidia drivers are the cause of the random hiccuping with the new rendering path on XP, but the old one has always worked flawlessly with my 8800GS so as long as you leave it there all is well

Well, I guess I would have to try a 660 myself with the old rendering path.....but the 700 serie is bound to arise and I have yet to find a 1080p LCD screen that'd make me happy, so it might very well take me half a decade to upgrade until OLED would finally hit stores(at reasonable prices )

Well, when I enable FRC in 90/96Hz I don't get the nasty 24/25p judder anymore for sure.......it's a hell lot smoother, the pop effect is drastically increased as well and it's just a real treat to look at. I think SVP also has a frame rate conversion option, not just interpolation....It would appear to me that you are making the movements smoother due to (mostly) imperceptible perfectly synchronized blending/"ghosting". I'm really hooked to it now!

BTW, you didn't answer me on my 0-255 source levels report, is that expected behavior at all

These features have no benefit for video rendering, but consume a lot of power.
I think its as its switch able graphics I am unable to use the AMD card. The 8730M is much faster then then HD4000 which I am forced to use. According to system minitor the amd card gets activated but for some reason its always 100ms+ on FSE mode.
On HD4000 I am getting 25 - 30ms upscaling 720P to 1080P using Jinc3 and Softcubic 100.
I need modified drivers to make the AMD card work.

4 is the default value for the number of frames presented in advance. I tried 12 but the queue still remains empty (0-12/12)

It's actually a generic workaround to support external media players that don't allow me to specify a message drain, only a window handle, but thanks for the suggestion. I've only recently added support for DirectShow and completely forgot about that method. It doesn't just host media players, but also game emulators, screen savers, etc. Disabling the window works 99% of the time, so I've stuck to this simple pattern for many reasons.

Basically, the auto-detected TV range looks washed out and I have to use the PC range that looks OK, but apart from some randomly pesky video files, PC range usually looks lighter than TV range so I'm kinda confused here?
Not sure what you did there. On my PC your sample behaves as expected. Meaning: PC range looks lighter than TV range. Maybe ffdshow has screwed up somehow. I didn't have ffdshow in the chain.

Have you tried the option "use a separate device for presentation"? Not sure if it works at all in your case, but it might be worth a try. In any case, do you need FSE mode? Maybe windowed mode works ok for you?

Maybe, I don't know.

What is your GPU, your OS and your GPU driver? What is your display refresh rate? Your movie fps? And do you have Smooth Motion FRC turned on or off? A screenshot of the debug OSD (Ctrl+J) in the moment when the presentation queue is empty might be helpful.

I understand. The problem for fullscreen exclusive mode is that madVR tries to make it work for any media player, regardless of whether it's aware of it or not. And it does work for all the media players out there (that I'm aware of) - seemingly except yours. If you can make do with the IVideoWindow method I suggested that would be welcome, then I don't have to change madVR. I'd like to avoid changing madVR's behaviour for just one media player. It might result in follow up problems with other media players...

Completely understand. I doubt that mine will ever be seen outside of my home, anyways. It's taken years to develop and is constantly in motion. I'd need more developers to make it publicly available.

put_MessageDrain didn't seem to improve anything. madVR does work fine in most cases, but the mouse wheel seems to give me the most issues, plus some overlapping keyboard shortcuts between the frontend and madVR. The later is easily solved and there may be an issue within SDL 2.0 causing the intermittent loss of the mouse wheel. Disabling the window just seems to care of all these issues in a simple manner.

The fronted is primary controlled by bluetooth remote and/or joystick, anyways, so it's rare that a mouse is actually used.

I only used ffdshow to check the levels, the very same problem occurs with LAV alone.....apparently it's due to my gamut mapping PS scripts(used as post-scaling in PotP):
Code:
// script=ps_3_0
// Code from MPC

sampler s0 : register(s0);
float4 p0 : register(c0);

static float4x4 r2r =
{
1.07521105249278,-0.0851867514203263,-3.55175263678786E-05,0,
-0.0256692518211088,1.06388788724376,-0.0340832039107225,0,
-0.0112108076565148,0.019277609404304,0.985946849621001,0,
0, 0, 0, 0
};

float4 main(float2 tex : TEXCOORD0) : COLOR
{
    float4 c0 = tex2D(s0, tex);
    c0 = pow(c0, 1/0.45);
    c0 = mul(r2r, c0);
    c0 = saturate(c0);
    c0 = pow(c0, 0.45);

    return c0;
}
Could it be that your BTB/WTW expanding "trick" gives the aforementioned issue if there originally was data in those areas somehow? Or maybe it's just not compatible with what this PS script expects? How could I fix it then please?

If I don't enable this PS script, then indeed PC is lighter than TV on this sample and this PS script works fine on 16-235 content.

Yes I tried that.
That breaks playback, I get blank screen but with audio.

With windowed mode and AMD card I still get around 50 - 60ms rander times and its jittery and lots of frame drops.
The card is not been utilized properly, gaming works fine. I think I need to stick with HD4000.

NVIDIA Quadro NVS 135M
Windows 7 ultimate sp1 32bit
drivers ver. 320.00
display 59.87547Hz
movie 23.976 fps
smooth motion off

since the 'display several frames in advance' only works in FSE mode a screenshot of the debug OSD isn't possible

You might be running out of video memory? Is it a 128MB or 256MB NVS 135M?

You can check video memory usage with GPU-Z. You might also take a look at how much memory bandwidth you are using while you are in there, 9.6GB/sec is pretty low for MadVR.
