Free calibration disk for Blu-ray players

AVS HD 709 has been updated to include AVCHD and BDMV versions that should work with Blu-ray players. Even for users without test equipment, it should offer most of the basic patterns you would need.

There are actually two color patterns on the disk. There's the Avia style one in title 1, chaper 4 and then there's the DVE type in title 7, chapter 2. I couldn't again quickly find the Ratatouille guide so I'm not sure what that disk is doing for color. The only description that I completely disagreed with in their manual was the setting for contrast (white-level) and how they were describing clipping, which often doesn't happen if you're using a digital display.

I think their patten for brightness (black-level) was a somewhat high APL pattern. The amount of light in the scene (APL) can change black-levels with some TVs and more light in the scene might also subjectively lead you to using a higher setting in order to make out the bars. In the Ratatouille guide by looking at the picture I think there was probably a good amount of jump between RGB levels. If you have a digital display I can't come up with any problem we've run across that might make either the 1 or 2 RGB changing bar patterns incorrect. If you have a CRT, you probably shouldn't be using Basic Settings (Title 1), chapter 1 because of the very low APL.

That's the first time we've had any report like that. You might try the .7z version. The program is small and you can always delete it if you won't use it for anything else.

The AVCHD ISO is UDF 2.5 I believe, so not every operating system is going to be able to look at the contents. I think you can burn it without issue even if you cannot read it. Unless the iso file size is zero, then I don't see anything there that necessarily indicates you're having the same issue as TrevorS.

The .exe will convert to a .iso file with windows, or the 7-zip software can convert the .7z to the .iso file. Once you have the .iso file (Approx 0.7 GB), you can use that to create the DVD. In imgburn open the .iso file and then write to a single layer DVD.

If you followed that and the AVCHD doesn't work, then my thoughts are to either try a different type or brand DVD or update your PS3 firmware if it isn't current. I don't have a PS3, but the disk has been reported to work with the PS3.

For anyone with test equipment the major advantage of this disk is that it offers 709 color. Except for burning w6rz patterns, I'm not aware of any other source at this time that does that. For anyone without test equipment, the major advantages of this disk are the black and white clipping patterns, which are basically the design of 3no. If your display has fine enough controls the black-clipping should be more precise than what's available on any of the commercial disks I've seen.

In short, for this type of compression zip is very inefficient.

On the mpeg2 HD DVD the 7-zip is 15 times smaller than zip. The AVCHD being H264 doesn't compress quite as well, and so it's only about 4 times smaller. To put it another way, the zip compresses to a file that's around 50% of the original and the 7-zip compresses to around 10% of the original. As it is it takes somewhere around 2.5 hours to upload the 7-zip and so it would take maybe 10 hours to upload the zip. We would also have to find a new host for zip because it would exceed the space filesend allows. In terms of compression size for these files and time it takes for conversion, I have not found anything better than 7-zip. Even though zip is convenient, it really can't compare for this application.

I don't explain how to use things like a light meter or HCFR with the disk, but the Basic Settings that most people are going to be interested in are explained under the TITLES AND CHAPTERS heading. The only other area that's explained at this time is chapter 2 from Misc Patterns. The one currently missing item that a majority of people would be interested in is sharpness/overscan/centering, which is our current focus to add in the next revision.

I'm not exactly sure what you're saying. I typically use Nero so I don't even know where the video or data options you mentioned are at in ImgBurn. If you were talking about Nero then those options are not what you need, you need the "burn image" selection in Nero. I try to avoid using the word copy because you're not necessarily copying the .iso to the disk. You need to use the .iso to create a certain type of disk. Here is the procedure to create the DVD in ImgBurn 2.3.2.0:

Go to mode pulldown - choose write
Go to file pulldown - choose "browse for file"
Select .iso file and open
Put a DVD in the destination drive and click write

If a DVD created that way doesn't work on the PS3, then the only thing I can suggest is to use a different DVD type because as far as I know that burning procedure should work fine. If you have Vista or another operating system that can read UDF 2.5 disks, the disk created should have a BDMV folder with a number of sub-folders. If your computer operating system can't read UDF 2.5, then you won't be able to read the created disk from your computer.
