I just did a quick little search for the VT50... I am sure it can handle 0-255 as well as 4:4:4... delve deeper into your manual and settings to find out how to make it happen.

madvr: RGB output leves: TV levels (16-235)

Is this correct? Thx in advance
AFAIK VT50 can handle 0-255.
You could change the option "HDMI/DVI RGB Range" to "Non-standard",and then set everything to 0-255.

Playback in windowed mode works fine ( fullscreen as well ), but switching on fullscreen exclusive mode, when going fullscreen causes black screen and the playback stops there.

Any hint please what blackscreens the FSE mode?
Thanks
in FSE settings.. lower the "how many frames shall be presented in advance" until a picture shows up..

some one helped me out with this before.. mine was set at 16 frames, and black screen, I had to put it down to 12.

Question guys:

if I use windows classic theme without desktop composition on Win7.. there's tearing in windowed playback mode.

is there a fix for this?

The option hdmi/dvi is not in the menu using a hdmi cable. Then you need to use a dvi>hdmi cable... Atm Im using a hdmi cable.

So there is no 0-255 wihtout dvi>hdmi...

(which is the general-purpose solution), or to
ATI CCC: pixel format: RGB 4:4:4 (Full RGB)
madvr: RGB output leves: TV levels (16-235)
(which is probably the preferred solution if you care only about your videos displaying correctly - be warned: anything other than madVR will display incorrectly, with clipped colors).

In your current setup, madVR squeezes the 0-255 RGB data into the 16-235 range, and later, your video driver squeezes that 16-235 data, which it thinks is 0-255 data, into 16-235 again!
The only way to get the tv to display this jpg picture below correctly is to set pixel format 4:4:4 limited (16-235). So I dont think Full RGB is correct for desktop usage either.


If the pixel format in CCC is 4:4:4 full (0-255) I only see 14 of the black boxes. When pixel format in CCC is 4:4:4 limited (16-235) I see atleast 27 boxes

Also using totalmedia theater i can see 17-25 in the calibration video flash when CCC is set to pixel format limited.. If I set CCC to full pixel format I see no flashing in the calibration video.

And with CCC pixel format set to limited and madvr to tv 16-235 I can also see the blinking. If CCC pixel format is set to limited and madvr to pc 0-255 I cannot see the blinking.

Therefore I conclude that the following must be correct fort the VT50 using a hdmi cable from the 280x:

ATI CCC: pixel format: RGB 4:4:4 (Limited RGB)
ATI CCC: Video: Dymanic range not selected
LAV Video Decoder: RGB output leves: untouched
madvr: RGB output leves: TV levels (16-235)

Are you viewing that picture using some image viewer or your media player? Remember that

Acdsee image viewer and paint gives the same result. Im not viewing the image in the media player.

I use mphc+lav+ madvr and arcsoft totalmedia theatre 6 to see the blinking 17-25 in the calibration video.

I'm using a GT50 and I have no problems with this, so your VT50 should support Full Range. Make sure you select Non-standard range on your TV options for 0-255. There are three options (Standard, Non-standard, and Auto), do NOT select Auto as it will not properly choose Non-standard when you feed it 4:4:4 RGB (Full Range). Also, madVR needs to be set to 0-255.

There are two modes for Windowed besides Windowed Overlay (Present frames in advanced enabled or not). Which mode are you using? Try the other one.

Just a quick question about SmoothMotion. When playing a 24fps film with tv at 60Hz the same applies as playing a 60fps film? As in keeping rendering time below vsync interval of <~17ms? Havent used SmoothMotion before, but I've gotten lazy and don't wanna add another filter in my chain(Reclock with 24fps-24Hz) and just use 60Hz with everything after a fresh Windows 8.1 install.

You should be able to use smoothmotion with higher rendering times; MadVR only needs to process the frames that are in the original film. The only exception to this is with dithering, but unless you're using one of the error diffusion algorithms that shouldn't be a problem.

SmoothMotion efficiency can vary depending on content. Videos with variable refresh rates can somethings be a problem for it, but then it can also be a problem without it.

Even though you say you don't want to use Reclock you might benefit from using them together. If you're planning on running everything on 60hz then you might find it beneficial to run Reclock at a forced divisible of that - namely 30fps or 60fps. (30fps would be closest to the original source, and less taxing on the system thus probably the best choice of the two). That should pretty much guarantee that you get smooth playback regardless of what video fps the source file may be.

I don't seem to have this option on my european model vt50. Maybe it's not there. Exactly where on the tv menu did you find this?

madshi, As a whole, is it possible to realise ability of MadVR to use all GPU's installed in the system simultaneously for processing ?

for none CF or SLI multi GPU system up it would slow MadVr down because you have to copy the datas from GPU to GPU this is pretty slow. so nothing to gain from intel IGPU and a normal one at the same time.

And what bandwidth does GPU-GPU FullHD 60fps stream copying take up?

Hi, can I get a hand please with creating a profile?

Seems that whenever I play wmv files fullscreen I get dropped frames (while with other formats I don't) so I need to lower the Image Upscaling just for wmv files down to Lanczos while with H264 I can leave it at Jinc3. I have tried to create a profile to do this but it doesn't work (still have the red explanation point in mVR).

if (codec = wmv) then "wmv"
else "Rest"

AND tried this (also no work)

if (wwv) then "wmv"
else "Rest"

"wmv" is Image Upscaling set for Lanczos while "Rest" is Jinc3.

Any guidance is highly appreciated!

it's 16 bit so a lot and it has a high impact on the general load too just look at AMD NNEDI3 copyback issue it's about the same issue and this is a very huge thing.
using a Intel igpu and a proper GPU at the same time is most likely slower else using only the discrete gpu.

and do you really think this is feature is worth time implementing? intel, nvidia and AMD behavior is not the same. intel and Nvidia are copyback with DXVA decoding (this is small data only 8 bit and it's subsampled too making it 12 bit compared to the 48 bit of 16 bit non subsampled)

but you can do the math if you like:
1920x1080x60x16x3 quiet some bits...

...and we have 5971968000 bits which is .../8/1024/1024=about 712 MB/s which is about 3x pci-e v.1 bandwidth and about 0,1 part of HD7770 memory bandwidth. So, 30 fps will be about 356 MB/s. But it is not necessarily to copy fullstream between GPU's if to use source stream splitting scheme where secondary GPU will be processing only a half of source stream (divided depending on specific implementation) and, thus, sending to the primary GPU (with connected monitor) a stream with a half bandwidth.
In addition, what about several discrete GPUs installed in the system but of the same vendor?
