Using the contrast setting of 13 would probably be a generally safe setting where 230-235 will not have much color shift. If you want to go higher than 13, to have brighter whites, just try to limit any color shift near white. The Grayscale Ramp pattern from the Misc Patterns can also be used to look at any shift toward pink near white.

Thanks. Why am I also seeing all the bars at the -1,1 and 7 settings? This is why I don't know where to set contrast(-1, 1, 7 or 13).

The bars disappear as the display runs out of available contrast. Generally at a low contrast setting you should see all the bars. I would suggest to get the maximum contrast and brightest whites out of the display you will want to try to use a high contrast setting.

Have you adjusted your gray scale? If you have not, you may just have too much red at the higher white levels.

I don't know how to adjust the gray scale. And I have no special equipment. For Blu-ray, I have the S&M disc, and the AVS709 test patterns.

For contrast you should be increasing until you see white flashing bars disappear, not lower. It sounds like you're going backwards.

Hello,

I have a strange problem.

I want to calibrate my projector contrast and brightness with Arcsoft TMT3, but in basic settings of the AVCHD 709 software in disc/folder mode I dont see any flashing bar...only black (brighness) or white (contrast).

I can see the bars flashing in TMT3 file mode but I know to setup brightness and contrast for bluray I have to run AVCHD 709 in disc/folder mode in TMT3 or other BluRay software.

File mode is good to setup movies in MKV.

Any help please?....thank you.

In Total Media Theater 3 I'm getting matching gray levels regardless if I play the patched disk or a file. I'm using an old ATI HD 2600XT card with current drivers on Windows 7 x64. There was a possibly similar report with the same program, but a different ATI video card at http://www.avsforum.com/avs-vb/showt...1#post18218821 There are a lot of things that you can do with software on a computer, and I know it took a while for some driver issues to be sorted out for my card. According to http://www.upsilonsoftware.com/blog/...nt-levels.html the software uses a different renderer between the two modes. I probably can't give any better overview depending on the video adapter than the last link.
post #2049 of 3881
Thank you for your help, but my problem is different.

I dont see any flash bars even I set maximum brightness (this is in TMT3folder mode).

I can setup without problems in file mode (see the flashing bars), but for bluray I have to setup in folder mode.

I do not have the stated issue. http://www.upsilonsoftware.com/blog/...nt-levels.html lists the program as using a different renderer depending on the mode selected. Without any further information I have to assume that the video chain is reacting differently depending on the renderer. Basically my best guess is that what you're seeing is probably related to the graphic card you're using. A thread on your graphic card or the prior link is the best guess I have to start troubleshooting what your computer is doing. The only other thought that comes to mind is to try another calibration disc and see how the disc mode reacts http://www.avsforum.com/avs-vb/showthread.php?t=852536 includes a free DVD that should have basic grayscale settings patterns, but unless Digital Video Essentials HD Basics happens to react differently I cannot expect that the issue is with the disc at this time.

Looking at the online specifications for the WDTV Live it appears that it will play MP4.
post #2053 of 3881
I have the Panasonic DMP-BD30 BD player connected to my Yamaha RX-V1800 AV Receiver and the receiver to my Pioneer KURO plasma all using HDMI. How do i know that the Pioneer is showing the AVSHD709 disc using the correct standard (Rec. 709) and not Rec. 601 or PAL. Does the Yamaha recognize the Rec. 709 and pass it on to the TV as it is? And if that's true does the TV recognize it as Rec. 709? Does the format used help (AVCHD or PATCHED)?

Let us know if it works. I've been thinking of purchasing a WDTV Live just for that purpose.

The easiest way to find out what is going on with the decoding is to measure colors. There is a pattern in Digital Video Essentials that is meant to be looked at by eye that has both the 601 and 709 colors, and the description there goes over what you may be able to notice depending on decoding. Personally I find the DVE description hard to understand on its own, so I recommend measurements if you really want first hand info on what's going on with colors on your display.

Somewhere in the video chain the YCrCb from the disc will be decoded to RGB. How the conversion takes place will depend on the device doing the decoding. By default most Blu-ray players will probably pass the info from the disc without converting to RGB. There are devices that can decode and pass RGB, but typically most standalone players will output YCrCb. Again there are probably receivers that can also decode, but by default a receiver would be expected to pass the video without conversion. So if commonly the player and receiver are not used for decoding, then the conversion happens at the display. My TV is a Sony and it decodes the colors depending on how it is set. By default my TV will decode depending on the resolution, so a HD input is decoded with Rec 709. In short how the conversion is handled will depend on where the conversion is taking place and how that device is doing the conversion, but in the quoted example the TV is most likely doing the conversion.

I decided to look further into how Digital Video Essentials would measure with a slightly different gamma when compared to measurements from v1.3 of AVS HD 709 (current known issue #1). It appears that DVE uses Y values 1 lower from 5% to 50% compared to what is currently on AVS HD 709. The AVS values are generally closer to the stated percentage, but the DVE values place the unusual step near black in a 5% or 10% series.

NOTE: 235-16=219, and 219 is not an even number so it doesn't allow for an even number of steps from black to white.

I don't understand why all the calibration discs aren't standard or uniform.

I have the WDTV Live running to a Benq W5000 Projector. I used the MP4 files. The play fine as long as you don't FF/Rew, which isn't much good. I used a program called Make MKV and converted just the parts I needed. The files play perfectly when in the MKV container.

I just wanted to say thank you to everyone involved in this project, and a big thank you to alluringreality. Great work.

could you please help with this issue.

I have a Pioneer KRP-600m display connected directly to a Pioneer bdp-51fd blu ray player via hdmi and playing the AVSHD 709 disc with the pattern to set brightness ( shows digital 1 to 25 ramp ). Irrespective of how high i go on brightness i can't show below digital 16. how do i set up the display and blu ray player to show below digital 16 so that i can accurately set the brightness control.
thanks.

I am not familiar with the player or display to comment if it's possible to show 1-15. You don't have to be able to show 1-15, it's just easier to see what's going on if you can display 1-15. Since you're not able to see 1-15, I would suggest using the APL pattern and setting brightness no lower than where you can see somewhere around 20 and up flash.

Along with explanations of how to use the things too. I downloaded one of these and got lost. I didn't have the manual at the time, but I later read it and still aren't sure what to do.

Aside from things like copyrights, part of the reason why test patterns and descriptions aren't entirely uniform is that TVs vary to some extent. Generally though there is some amount of agreement for setting brightness, contrast, color, and sharpness controls. I know that I found patterns frustrating the first time I looked at DVE and Avia, so asking questions on how to make adjustments or stating specific issues is welcome.

Sorry for the reply in French.

Le disque AVS HD 709 n'est pas un film. Il contient juste différent écran ou mire pour pouvoir régler ton écran télé ou projecteur. Il y a certain mire plus facile a utiliser que d'autre. Les testes de contraste et de brillance peuvent être fait visuellement, mais la pour plus part des testes couleurs il faut avoir une sonde de colorimétrie.

Il y a aussi le site http://www.homecinema-fr.com/forum/ en Francais qui peuvent peut etre t'aider.

Hey guys - I just downloaded the PATCHED version to calibrate my Vizio M220VA with my Sony BR BDP-S300 and need a bit help here. I got all the software running on my player, I'm just unsure of how to use it. Which tests should I use? There seems to be so many. If it matters, I will mainly be using this TV for gaming. I also don't have a blue filter so how do I adjust the color settings?

The patterns are intended to be used with a colorimeter and corresponding software. The colorimeter measures the amount of light and red, blue, and green being displayed from the various greyscale patterns. You can read the thread on HCFR for more information.

If you are not prepared to spend a lot of time learning the process and couple of hundred dollars for the meter, then you can do one of the following (listed in lowest to best results)
- use setting posted by other users with the same model TV and adjust by eye to a acceptable level of display
- purchase one of the calibration DVD that come with red, blue, and green filters
- hire a profession to calibrate the TV
post #2068 of 3881
Oh wow, I was not aware that I needed to purchase a colorimeter. Is there a thread on this forum identifying users with the same TV model as me?

Also, if I purchase the DVE HD Basics DVD will I need a colorimeter for that too?

http://www.walmart.com/ip/8462130

I'm really just looking for a cheap and simple way to calibrate my new TV. Any help is greatly appreciated.

If you look at the end of the first post in this thread there are links to "Patterns" documents which have instructions on using the disc without meters.

DVE HD Basics is the same sort of thing; it has more onscreen help and audio tests.

post #2070 of 3881
Oh ok, so with DVE I will still need a colorimeter?

And are you talking about the .pdf's at the end of the first post? If so I downloaded those and am still a bit confused. Where am I supposed to start?
