Just a thought:

For selecting deinterlacement ON/OFF and video/film mode it might be cool to add a translucent type of toggle button in the osd that one could simply click to change stuff as an alternative to the tediousness of long hotkey activation.

Probably you're lucky and your audio hardware clock deviates just in the same way from the ideal timing as your video hardware clock does.
But regardless of audio/video clock deviation, 23.976 material running on 23.973Hz video signal (thats what madVR says at statics on display) should produce a dropped frame every 6min aprox.

I assume for a 0 dropped frames scenario (besides a powerful enough system), audio clock to be sync'ed with framerate and this one with refresh rate, is needed.

Are you sure your not using reclock?

Absolutely; in fact I've just installed it right now to see if it can fix this problem. Shit, one of the reasons I picked up an AMD card was to get rid of 3:2 pulldown and its judder. And now this...

It doesn't even output 24Hz right, it does 23.997Hz (says madVR statics). Yesterday watched a full movie with 0 dropped frames at the end. Today, on another one 25 dropped frames!!. Same circumstances, I started each playback right after restarting the PC.

Im gonna check what reclock says about refresh rate, in case madVR is wrong about detecting it correctly.

You should set it to 23, that is 23.976, 24 is 24.000

Depends on what you are playing; for 24fps material, like the movie I watched today, 24Hz output should be setted. I just was saying that my f*cking GPU (AMD 6950) does not even output 24Hz right, it does 23.997 instead 24.000. Same deviation as on 23Hz mode.

Tried the rest of supported refresh rates on the gpu and this is what I get:

23 Hz -> 23.973
24 Hz -> 23.997
30 Hz -> 29.997
60 Hz -> 59.996

All faulty,

23.973 isn't exactly "faulty". I'm not even sure the rarely dropped frame would be actually noticeable. Don't expect to get perfect 23.976, not many displays are capable of exactly that. If you are really concerned you can just run your display at 23.997 and use reclock to speed up 23.976 material slightly (as it seems films are shot in 24fps and then slowed down for compatibility with NTSC displays).

@ madshi: the lipsync bug was obviously not madvr related, it rather seems to be related to my monitor taking too long to change the display mode and JRiver by default not waiting long enough to start the audio (fixed with the "play silence" setting). In MPC the problem never happened.

So all is fine

I think it depends on the display too, but most people have refresh rates very close to perfect with AMD cards. 23.973 was what I was getting with NV GTX460 out of the box, IIRC. Again, with my 5770 I get ~23.97590 and similarly close rates for 24, 50 and 59.

Well Im not saying I cannot live with it, but would like to get rid of it. For you to know, it feels like a stutter, a visual glitch every 6 min; but thats not all... is that every time you get that video glitch you also get a 42ms lip-sync slip as well

I dont think it is the plasma. With a Dell monitor via displayport, it does not outputs the 60Hz exactly neither, it does 59.996, the same as with the tv... too much coincidence. Its definitely the goddamm gpu.


BTW is it possible with reclock to adjust the fps speed to that specific refresh rate? I mean, 23.973 or 23.997. Or does it just work for the predefinited ones 24.000/23.976 only?

Since 23.973 and 23.997 are the ones madVR statics shows on 23hz and 24hz gpu output modes.

ReClock automatically adjusts to the proper screen refresh, as long as its close enough to the target (you can configure the limit in the options, default is 1%)

Unless you are using Coax/Toslink connection (HDMI or Analogue are be preferable) and need to bitstream audio, you should be using ReClock, with your display at 24.0Hz in my opinion.

Considering that most video cards seem to have trouble with 24/1.001, unless you actually have 23.97602, you're better off at 24.0. Even 23.97602 does not guarantee that you have the exact sync correct.

Even a single dropped frame or presentation glitch is very noticeable in my opinion. Unless you're blinking when it happens, it's hard to miss.

When framerate is set to "Auto" in ReClock and it reports entering CINEMA Mode, it is adapting to your video card clock in realtime.

Ignore anything madVR says about estimated dropped frames (there should be none when using ReClock, unless your GPU is dropping frames because it is too slow for madVR) or anything ReClock says about refresh rates/framerates.

I think it may actually have been fixed in the latest version (not at my PC to check) but for a long time ReClock used to say that CINEMA Mode was setting the framerate to 24.000 fps which was erroneous. (ReClock was working correctly, the message was wrong)

If you can, I recommend using WASAPI audio output with ReClock, upsampling to the highest bit-depth your soundcard accepts, and 96kHz audio. (going beyond 96kHz actually degrades audio quality) Until you get this right, you will probably get a lot of errors about unsupported formats.

WASAPI audio can be trickier to set up though, so if you're having trouble, you may want to skip it and let Windows handle the audio output.

You need LAV Filters if you want GPU-accelerated decoding with madVR.

You're saying Reclock is here adapting framerate to 23.997 (actual GPU refresh rate in 24hz mode), and not 24.000?



madVR still reporting dropped frames I think madshi said not to take serious the "1 frame repeated every" estimation, but NOT about the "dropped frames" meter.

Thats just a display thing, it'll sync to your display refresh rate as close as it can.

Correct, it's being resampled to 23.997 there, and will change if your refresh rate fluctuates. Unfortunately ReClock development is finished now, so this will never be fixed. It's the text that is wrong, it's working correctly.

What is your CPU usage like? Have you tried a different video decoder?

What about GPU usage? Have you tried setting madVR to bilinear scaling, and reducing bit-depth to 10-bit with no dithering? (far from optimal image quality, but can lower GPU load considerably)

I do agree and that's exactly why I'm using the old exclusive mode (seems to be impossible to get glitch free playback on my machine with the drivers I need for my games).
However, in my case there should be an occasional dropped frame (71,93/23,976 and I don't use Reclock) -I don't remember how often exactly- but I've never seen it. madVR keeps saying "1 dropped frame every 10 minutes, 1hour, 1 day" etc without any consistency (just like when using Reclock).
With 24fps content however I definitely notice the jump every 41 seconds and madVR does show it correctly. (but my display can do 72,001hz too anyway)

That's why I'm asking kerman if he sees anything wrong in the first place, you can't just blindly trust all these numbers. But since he also sees dropped frames in the stats he's got a problem other than hz/fps sync IMO and Reclock is not the answer.

Q6600@3.60GHz rarely goes over 4-5% during normal playback
GPU is HD6950 2GB and unlocked (shaders) to HD6970

Do you still get dropped frames if you use the new exclusive mode, or run it in windowed mode? You may have presentation glitches, but at least it's another variable to test.

Ignore anything madVR says about estimated frame drops.

I have automatic fullscreen exclusive mode enabled. Im wondering if I have to change something on Catalyst control center , under "Advanced Video Color" or "Video Quality"...

Is it possible the dxva2 on LAV decoder to have something to do with this in anyway? Just to discard options to isolate where the problem relies. Maybe it be the plasma after all. Dont have any other laptop to try though...

Regarding to madVR, is it still of use when not resizing the video? I mean, for 1:1 pixel mapping (1080p) material, where no scaling is needed, regardless of this, does still improve the image quality anyway?

vertical lines in grayramp

I have just tried the madTestPatternSource tests and I can see vertical lines in the grayramp.

Here is a screenshot madvrgrayramplines.jpg

This is with madvr 0.80 and MPC-HC 1.6.1.4055.

Any idea what's causing these lines? Is this pointing to a problem with my graphics card?

My graphics specs are
Code:
Operating System:	Windows Vista (TM) Ultimate, 32-bit (Service Pack 2)
DirectX version:	11.0 
GPU processor:		GeForce 8600 GT
Driver version:		285.62
DirectX support:	10
CUDA Cores:		32 
Core clock:		540 MHz 
Shader clock:		1188 MHz
Memory clock:		700 MHz (1400 MHz data rate) 
Memory interface:	128-bit 
Total available graphics memory:	1279 MB
Dedicated video memory:	512 MB GDDR3
System video memory:	0 MB
Shared system memory:	767 MB
Video BIOS version:	60.84.41.00.00
