My plasma shows 24p at 96 Hz. Looks great, aside from the edge-quadrupling but that's only visible on certain panning shots.

24p@96/120Hz looks great on a CRT, a hell lot better than on a LCD but then again mVR's FRC still does its blending magic to my eyes

I'm with you on the PWM issue. I hate it. Then again, I also hate LCDs in general

madshi,
would you, please, add a link to your recommended lines in the first post of the current thread? This will make it a lot easier for beginners in calibration like me.
madshi the first post in the AVS forum thread was updated on 22.08.2013? Does it still NOT represent your recommendations ... which btw I still haven't found in the AVS forum ... or I'm not exactly ceratin that I did and I'll be very glad if you can post a link here.

a newbie question about upscaling:
what would be better (with more quality) to watch:
1) 720p upscaled w madVR to 1080p desktop resolution
2) 720p at 720p desktop at 1080p monitor ?

If you have a 1080p monitor there will always be scaling for playing 720p content (in most cases even for 1080p content due to chroma sub-sampling). For 1) madVR does that scaling, for 2) the monitor does the scaling. I don't know how good your monitor's scaling is, but the scaling madVR does is very good so I would go with 1).

Anyone knows how can I set madvr to use the radeon 7870 for acceleration when the output is set to my onboard gfx card?

Depends on whether your monitor is any good at scaling or not. In my experience, monitors suck at scaling. TVs on the other hand range from terrible to fantastic. My TV scales Wii 480p content exceptionally well - it's just a shame that Wii games don't tend to use anti-aliasing, otherwise they'd look great.

He has yet to tell me which types of videos this happens (like their fps and whatnot) but I want to hear everyone's opinions, as this might be something that has already happened around here.
Are you using hardware accelerated decoding? Software decoding seems to be less error prone.

Use madVR to scale.

dansrfe,
thanks a lot for the link. I usually read very thoroughly and don't know how I've missed it ... well I think I know now - your post is above mine ?!?!? How is this even possible? May be some forum glitch.
Anyway thanks - I'll play around with these this weekend.

I guess I figured it out. It's specific to one movie. It seems to have a much bigger spread of rendering times than other movies. Generally the rendering times are quite low but for some scenes they're quite high. After such a demanding scene if the maximum rendering time drops a lot (which I guess correctly reflects the timings) then the average rendering time needs quite some time to catch up. That's when the latter is much higher than the former.
Sorry for not seeing the obvious earlier.

So, if i have a 1080p PC monitor that can change resolutions to 720p or 480p, using MadVR internal resolution switch, you guys are saying i should leave the monitor at 1080p always? Or use the resolution switch?

MadVR will almost certainly scale better than your monitor, so leave it on 1080p.

It's always best to use the native resolution of your monitor. Let madVR do the scaling work instead of the monitor's internal scaling. For myself that meant using the rectangular pixel resolution of 1024x768 (I have a 2007 LG 720p Plasma)... Just make sure 1080p is your "native" resolution.

I'm not sure how I forgot to ask him something so fundamental. I'll get that back to you when I have it.

Also a question for display experts out there. I'm in a dilemma between IPS and TN. On one side I can get better colors but no 120hz (which is kinda sad for my casual gaming and video smoothness) but on the other side I can get the best smooth experience ever (but with not so good colors thanks to the bad viewing angles).

Does one side has any other benefits which I'm not aware of that might help me make my decision on which one to go for? I'm aware that we have IPS displays that can be overclocked to 120hz, but those need to be imported AFAIK and I forgot the name of the other company that makes those around here...

And this occurs with all movies? Please double check the OSD to see whether deinterlacing is actually enabled and film mode active when forcing film mode. Maybe the movie is detected to be progressive? In that case forcing film mode won't do a thing, but using the file name tag might force deinterlacing on. Not sure, though, just a guess. At least that's the only way I can imagine why the problem would only apply to the file name tag...

Please don't post your question twice.

Personally, I've no idea how that virtu stuff works. madVR behaves like a game. So whatever you do to make games run on your 7870 should in theory also work for madVR. If it doesn't then I don't know why, or how to make it work, unfortunately...

Everything seems to play buttersmooth, but during specific tiny movements (typically a slow moving object in the distance or background) I notice some stutter, exclusively focussed on that object. it's like the object jumps from one place to the next (but very subtle) and there are some frames missing in between.

But even during these moments, all other motion and all other objects of the image are perfectly portrayed. The statistics also show no frame drops whatsoever.

My best guess: some motion detection algorithm is playing the wrong tricks?
Is this with DXVA deinterlacing? That's the only part which might treat some parts of the image differently than others. All other algorithms used by madVR don't do such a thing atm...

I thought having the queues filled completely was good but it's faster if the present queue is not by setting the present queue higher than the render queue.
Is this in windowed mode or overlay mode or fse mode?

Generally, playback should be more reliable the bigger the queues are. The smallest queue can be the bottleneck. It's better to have a 2000 frame queue which is half full than to have a 4 frame queue which is full. So it doesn't really matter if they're "full" or not. What matters is how many frames are stored in there. So setting the queues higher should usually help stability, as long as you're not running out of RAM and if the GPU driver doesn't have a problem with the queue size. Of course big queues mean slower OSD reaction. A larger presentation queue also means slower windowed <-> fse switches. So it comes at a price.

I'm not sure, maybe Direct3D gets stuck/slower when the presentation queue is full. It shouldn't, but I've not written D3D, so I can't vouch for what it does.

Looks like a problem with DXVA decoding to me. Or the GPU hardware is broken.

-24p@24Hz + BFI: hardly anymore backlight flickering and the synced BFI hides motion blur amazingly well. The flip side of the coin is that it acts as a motion-based EE and the picture looks really "colored" for lack of a better word. The subjective pop effect is highly increased but it doesn't look natural, it really has a "digital" flat-screen look.....my brain is not tricked into believing that it's watching through a window(the original intent of HD video). I can literally "feel" the syncopated shutter of the BFI and that really gives a "digital" unnatural look. 24p judder is still there and it's painful.

-24p@60Hz + mVR FRC: Ah, goodness! This time the motion blur doesn't hide/cheat anymore, it strives to make things look a hell lot smoother. Pop effect is astounding, 24p judder is history and it literally makes me feel like I'm watching through a window, too good to be true

OTOH, once BFI is disabled the darn backlight flicker becomes very annoying
Two comments:

(1) Why is there more flickering with BFI turned *OFF* compared to turned *ON*? Normally BFI introduces flickering, it doesn't remove/reduce it!!!

(2) When you're talking about "24p judder", do you mean the judder that the lower framerate of 24fps naturally comes with? If so, 24p@60Hz + mVR FRC should show it exactly the same way. If 24p@60Hz + mVR FRC is smoother for you than the native 24Hz modes of your display, then I would bet on that your display doesn't handle 24Hz "correctly", instead it probably does a 3:2 pulldown internally. If that is the case, what you're seeing is not "24p judder", but instead 3:2 pulldown judder introduced by your display handling 24p input in a bad way. If you had a display which handles 24Hz input correctly, it should be just as smooth as 24p@60Hz + mVR FRC is.

I've said it right from the start: The higher the refresh rate, and the lower the framerate, the better smooth motion FRC works. I might be able to improve the smoothness when framerate and refresh rate are near to each other, but if I do so, it will cost quite a bit more sharpness in moving parts of the image.

If you're looking for a computer display, I'd prefer an IPS panel, except if you're a heavy gamer, maybe. If you're looking for a movie display, I'd much rather recommend a Panasonic plasma, or one of the new OLED displays from LG or Samsung if can afford that. But that is a hot topic, and a matter of taste (some people don't like plasmas, while I personally like them much better than LCDs for movie watching). So please let's no go into this in any more depth.

Need HELP gathering samples for future madVR algorithms.

Basically I'm looking for samples which have all kinds of black bars encoded into the video area, either top/bottom, or left/right, or even all around. The weirder the black bars are, the better. E.g. if the top bar is smaller than the bottom bar (as is the case with some Japan broadcasts because they place subtitles under the Cinemascope video area), that would make a great sample.

If there are logos or burnt-in subtitles in the bars, that would be nice, too. They can be partially or completely in the black bars. Also interesting would be samples which have black bars with raised black levels. The higher raised, the better. Basically any sample which is weird in any way: Send it to me!

Just very small samples (like 3 seconds of runtime or so) will do, although if you want to upload larger samples, that'd be fine with me, too. If it's a sample with subtitles in the black bars, then maybe it would make sense to make the sample a bit longer, so that the sample contains both (1) frames with subtitles visible and also (2) frames with no subtitles visible.

Please don't expect those "future madVR algorithms" soon, and I'll also not comment on what exactly those algorithms will do. Maybe you can guess, based on what kind of samples I'm asking for. In any case, I'll not comment on the algorithms until they're done and available. Thanks!

Yes yes I'm sorry! I forgot to ask him this question because he said he didn't use any settings other than default so I assumed this wasn't an issue.

Okay. I've read that plasma fixes a lot of the LCD issues so I understand your reasoning. I'm not much of a gamer (just casually play some fps to pass time) so maybe IPS display is the ideal, thanks madshi.

Hi madshi,

I got a file (32 MB) to upload:

Sorry I don't know how to make it shorter, due to the vp8 format.
