This is for converting the video's gamut to the display's gamut and displaying with the desired gamma, not doing what I would call a full calibration as is done with a "normal" CMS. |

Found an example of incorrect ITU scaling on an HD upscale of SD material broadcast on E4 HD:
DVD = ITU (702x576= 16:9) HD Upscaled = full-frame scaling (720x576 = 16:9) HD Upscaled adjusted for ITU The HD upscale has more of the frame visible but I'm not sure which one of these is correct in terms of scaling. The black bars on either side of the HD upscale suggest that the DVD might be correct - if true, it's a shame that a public service broadcaster can't even get this right.

RGB level
Hello,
Been following the RGB level discussions of the last few days in this thread and I'm not sure how I should have this configured for my setup. My TV does not seem to have any settings for this but from what I can gather online it supports 0-255. So assuming this is correct, how should I setup CCC (Radeon 6570), madVR, and LAV video? I use my HTPC for viewing photos and media playback (BR rips, AVCHD camcorder and GoPro footage). Thanks, ->g. |

(I think so especially because in the nvidia panel, for "Digital Color format", changing between RGB <> YCbCR444 makes 0 difference when it comes to color levels) (Desktop) If I open paint shop pro and test colors 000000 to 161616, it's perfectly black. I do start to see (extremely faint) grayish around 171717. (video) If I play videos at 0-255, I suffer majorly of burnt blacks. If I force madVR to 16-235, everything is fine, including the calibration files (1-Black Clipping.mkv, 2-APL Clipping.mkv & 3-White Clipping.mkv). Quote:

But regardless of the issue i'm experiencing, I still disagree on the fact that the best solution to "unify" screenshot color levels is to use PC levels. After all the sources aren't the same. It makes sense for vacation photos or anything coming out of the PC world to be in PC levels. But again, in the video world as we both know, 99% is in 16-235 color range by definition so taking "screenshot" using this color range makes more sense to me, if only to allow comparision with "screenshot" from other renderers which seem to be outputting 16-235 by default.

I only have "Settings" > "Picture" and "Settings" > "Video" (in which i can only alter/force the color format NTSC/PAL, etc..) I do see a huge difference when I force the PS3 to output RGB full versus RGB limited, if it's any indicator.. Quote:
I still do think the driver outputs 16-235 and my TV expects 16-235. Everything on the desktop that is really between 0-16 is brought back to black, so of course I suffer black crush for the desktop/pictures etc.. Is this reasoning flawed?

If the card is outputting 0-255, and the display is set up only to accept 16-235, then anything outside the 16-235 range will be clipped. It should like you have inadvertently managed to force 0-255 output when your display doesn't support that, and you should be sending it 16-235. Even if you don't have a levels option, some displays will clip anything outside 16-235 by default, but it's not a hard clip, and you are able to use the brightness & contrast controls to have them display 0-255. (other displays that have a hard clip to 16-235, will never show anything outside the 16-235 range) Have you tried that? There may also be a "super white" or some other option to switch your display's levels though. EDIT: I've just read through your TV's manual and there doesn't appear to be an option for this. Strange, I thought all the XMB-equipped models had it. The first thing I would try is switching to the "graphics" scene mode. If that doesn't work, try adjusting brightness/contrast to see if you can make levels outside 16-235 visible. If that doesn't work, you need to get your GPU outputting 16-235, and not 0-255.

this is an (black white) 0 - 255 PIC..on my CRT i see all color differnces..on my HD TC however i do not..on my hdtv i use 10 - 255 and its perfect now thanks to madshis custom color range option..

I found an annoying issue with madVR. On several .vob/.mkv files which are 30i, using LAV Video to decode it(software) results in deinterlacing being activated. The same is not true of madVR's built-in decoder. it says deintertlacing off (framerate).

I FINALLY figured out why I'm getting dropped frames in madvr. Its leafs. Scenes with lots of green leafs, trees, and that sorta thing make my GPU usage rocket up to 100% and madvr starts dropping frames like crazy. Is there anything that could be done to make madvr handle leafs better? If it matters, I'm using Jinc4, and my GPU Is a GTX460.

It's leaves
I believe Jinc 3 AR is slightly less demanding than Jinc 4 AR so you could try that. If you still have frame drops and you want to keep using Jinc then I'd recommend overclocking your GPU or selecting a less demanding Chroma algorithm otherwise choose Lanczos 3 AR instead. |

Another question if you don't mind. My Plasma can do 60 hz and 48. It's a panasonic st30. When I send it 24p, I can switch to 48hz, but it has horrible flicker, so that's a no go. So, I'm left with 60hz. My question is, I can have madvr switch the refresh rate to 24p, which means the tv does 3:2 pull down. The tv says the option is off, but since there's video playing on the screen, it must be doing 3:2. My other option is to not do refresh rate switching, leaving the video card at 60hz. Does that mean madvr is doing the 3:2 pulldown or is it my vid card? Which is preferable, letting the tv handle it, or sending it already switched? |

Madshi, I'm using a AMD 4870 with 12.6 drivers on Windows 8 x64.

Yeah, horribly OT, but it seems a slow Sat. But definitely try something less demanding than Jinc4 |
