Advanced MPC-HC Setup Guide - Page 18

My configuration:

HP G62 laptop, Intel® Core i3-330M Processor (3M Cache, 2.13 GHz); integrated graphics; RAM 3Gbyte.

Playing 1080p movies, fullscreen exclusive mode, I get dropped frames here and jerky playback.

Under GPU-Z sensors log GPU isn't overloaded. Scaling algorithms softcubic and bicubic.

Can someone help me, what madVR OSD statistics terms mean? (Upload-, render-, decoder-, backbuffer queue; average stats, max stats, vsync interval etc.)

First,

- frame interval = 1/(frame rate)

In NTSC countries, movies are usually 23.976 fps, so

- frame interval = 1/23.976fps = 41.708 ms

Videos are 59.94 fps, so

- frame interval = 1/59.94fps = 16.683 ms
 

  origin format what video renderer receives frame interval
SD film film-based 480i60 480p24 41.708 ms
SD video video-based 480i60 480p60 16.683 ms
HD film film-based 1080p24/1080i60(broadcast) 1080p24 41.708 ms
HD interalced video video-based 1080i60 1080p60 16.683 ms
HD progressive video video-based 1080p60 1080p60 16.683 ms

Sample clips:

- SD film: Ratatouille (2007) (480i60, MPEG-2, AC3)
- SD video: Die Zauberflote (2003) (480i60, MPEG-2, AC3)
- HD film: Iron Man (2008) (1080p24, AVC, TrueHD/AC3)
- HD i video: La Traviata (2010) (1080i60, AVC, DTS-HD MA)
- HD p video: La Traviata (2010), created from the above by deinterlacing with yadif (1080p60, AVC, DTS-HD MA)



(Average) rendering time is the (average) time for madVR/GPU to process a video frame. To play without dropped frames,

- (average) rendering time must be < frame interval

obviously (otherwise madVR/GPU can't render video frames fast enough without dropped frames). Playing back a film is a lot easier than a video in terms of rendering.

On the other hand

- vsync interval = 1/(desktop refresh rate)

If vsync interval differs from frame interval, there is a periodic frame repeat or drop. VSYNC (vertical synchronization) is the most important notion for smooth video playback. Technically it is a signal or an impulsion that occurs within the vertical blanking interval and marks the start of a new frame on a TV, monitor, or projector. References: VERTICAL SYNC, a blog on this subject; How VSync works, and why people loathe it in gaming context; "Using the VSYNC tools" in ReClock readme.

Queues are buffers (video frames in memory) to be processed.

- decoder queue: in decoding
- upload queue: in uploading buffers from system memory to video memory
- deinterlace queue: in deinterlacing
- render queue: in madVR rendering (= chroma/luma scaling)
- backbuffer queue: in displaying

All of them should be near full, otherwise dropped frames could occur. For example, low decoder queue means that there is a problem in video decoder. Low render queue means that your GPU (stream processors + video memory) is too weak to perform madVR's rendering algorithm.

Thanks to your help.

My madVR statistics attached.

Can you help me, what is wrong with it?

The main problem is: render queue 0-8/8. Perhaps the scaling algorithm is too heavy for your GPU.

Display 50Hz and movie 23.976Hz means that there are frame repeats every second. If you don't like this and your display can't accept 23.976/24Hz input, ReClock PAL speedup is a work around (video playback rate is increated to 25 fps).

Full screen exclusive mode. Screen capture was a failure.

In full screen exclusive mode alike.

SAMSUNG PS50B550 plasma. User manual specifications: PC resolution: 1920 x 1080 @ 60 Hz.

The panel displays at 60 Hz regardless of the input signal?

In general PC mode is a wrong mode. Try another HDMI input. The resolutions/timings supported by the display are seen in Intel graphics properties.

As far as I know you can not. I tried it the other day and MPC locks up, video plays ok but I had to freakin restart to close the damn thing.

please help me to get dtshdma sound from the movies.

i have try all of the setting if i cannot get it to work.

one time i get it the receiver towork with dtshdma but it jittered alot that i cannot watch it.

i try the setting on this first page. i still cannot get it to work with it.

pc config:

a8-3850 with mb
receiver: onkyo sr-309

all connection is hdmi 1.4a

htpc - receiver - hdtv

i have installed LAV filter, shark007 , Madvr.

Madvr is the video filter. LAV filter is the sound decoder. i dont know why when i play it i

You say LAV Audio filter is your audio decoder, but in your screenshot it shows ffd audio.

im gonna say its because you are using an old ffdshow for audio.

so what is the new ffdshow for audio? i am using either shark007 ver. 3.5.5 and ffdshow-rev4158_20111217_clsid.

are both the new version?

Well, the way MIND has it set up in the original post, you need to make sure you aren't using the ffdshow audio decoder

I'm using it with a Clarkdale I3 and it works fine with one quirk: When using MadVR to deinterlace 1080i BluRay, if the OSD is on it shows an error message "deinterlacing failed". But in fact the material is deinterlaced fine.

My configuration: HP G62 laptop, Intel® Core i3-330M Processor (3M Cache, 2.13 GHz); integrated graphics; RAM 3Gbyte.

madVR scaling algorithms: chroma upscaling, luma upscaling, luma downscaling: all of them nearest neighbor.

Playing 1080p movies sometimes dropped frames occur, otherwise smooth playback.

Playing only 1080p movies, have any importance which scaling algorithms are used?

For 1080p/i, only chroma upscaling is important.

I think bilinear is the least processor intensive.

Getting back to my earlier question. I think I ran the setup correctly. Everything plays nice and I get the sound but I lost the ability to skip forward through the bluray iso's.
I had it with the 64 bit version with the 64 bit version of ffdshow but I switched it to the 32 bit MPC because of picture issues
I assume that nodbody else has this problem?

dunno what it would be

have they fixed MPC-HC seek (ff/rewind) in the latest version? I have never been able to get it to work the way it should. Only jump ahead whatever specified time I set up.

I saw a very decent HP AMD quad core minitower on Woot two nights ago for $299. Just add a GT 550Ti from newegg and you have a $420 HTPC with OS that can play anything you can throw at it. Install the Nvidia GPU, install JR Media Center and set it to ROHQ and your video playback is pretty much state of the art and a no brainer all at once.

hi, just found this and read a few pages, don't know how to read all of it, was hoping someone could help me, a couple of probably basic questions, how do I get the display stats to come up for madvr? display stats is greyed out in mpchc where I normally get it for evr custom pres. I assume I can still use full screen auto switching display rates from mpc-hc with this?

finally I have the same problem other people seem to be mentioning, the playback is never fully smooth, when I play side by side 1080p mkv's I get some jutter or jerkiness every once in a while.

I"m running gt430 video card and 2 ghz amd athlon x2 cpu. i've been using ffdshow accelerated decoding as it seems to use a little less cpu processing but I also have lav video cuvid setup and am game to try madvr if it will make things better.

I set my refresh rate to 23hz in nvidia and according to the stats in mpc-hc, everything is pretty damn near perfect except the sync offset climbs slowly until it resets itself and of course I notice that twitchness, I can attribute sometimes to a bad encode, but its definately not what it should be.

cool thanks.

for anyone that knows, I'm still supposed to match my refresh rate to the source video using madvr right?

edit: in exclusive mode settings, the bottom 3 things that you shouldn't use unless you have to, is there a guide on those or anything that explains them? i checked all 3 and presentation glitches seem to be gone.

LAV has perfect decoders, but has no post processing features (avisynth support, downmix 5.1>2.0 etc). Someone might need it and here comes ffdshow video/audio processors.
