No, the ISO should be correct. He was saying that someone else converted the png files to mp4 which were then used to make the ISO file.

No, the iso is fine. I need mp4 files like DrFaxe posted to author another. I do not have the software to create mp4's from png's. Chad posts his pattens in png format.

It plays perfectly on my Panasonic BD655, Sony 360, and my Denon 1800BD, both DVD+R and DVD+RW discs. Maybe I should upload the folders and files, the ISO may have been corrupted somehow. Each pattern should play for 5 minutes. The iso can be tested on your pc if you have powererdvd, expand the iso to your hard drive and select the folder. If it plays correctly there is a problem with the media,or the burning speed. I've had some dvd's that had problems with burn speeds over 4x even though they were rated 16x.

Let me know.........

The avs709 does the fast skip thing in the Samsung as well, always did. I will burn another copy and try the Panasonic again, maybe check firmware but I always fear updating it as who know what can happen to the out accuracy afterwards.

They are all generated with video levels, with black at 16. If playing on a media server, RGB PC levels should be used. Also, the .PNG format makes them ideal for use with the VideoForge pattern generator, which is how I use them now.

First are some normal (non APL) very small windows. They are approximately 4% size. normal 4% windows with pluge.zip 116k .zip file

Second are the same window sizes but in APL flavor loosely based on inspiration I got from the AVS 709 APL windows- thanks Alluringreality! They are in between the AVS 709 large and small APL size. apl 4% windows with pluge.zip 523k .zip file

Third is some miscellaneous patterns. custom test patterns.zip 97k .zip file

The gamma pattern is especially useful for checking 10 point white balance control mistracking. Example: with settings at default, take the blue (or whatever color you want to check) control at, say, 80% and turn it all the way down. Then display the gamma pattern. Run the contrast control up and down and observe if the discolored square remains at 80% or if it moves up to, say, 90%.

The color pattern can be used with the color filters for a quick meterless check of color decoder nonlinearities, as it has matching levels at 50, 75, and 100%. If red, for example, blends in with the gray surround at 50% (bottom horizontal row) and 75% (middle row) but is darker than the surround at 100% (top row), you know your color decoding is nonlinear and you can take steps to correct it (lower contrast, change panel brightness, etc).

The aspect pattern is handy for adjusting anamorphic lenses or lens memories on front PJs.

NEW!

does the iso in the above link include the two new pattern types below and are the levels all verified to be correct (RGB triplets or whatever their called)?

the iso was made previous to these last updates from Chad. The patterns were tested against the avchd patterns and checked ok.

These new reduced saturation patterns I made sure had the same RGB tripletts as what CalMAN asked for for each respective color. Wouldn't hurt to have a second verification, though.

do you mean ps3? it probably will not work as the file structure is different for the ps3.

Why pattern 75% Saturation / 75% Level
Blue - 58-58-123 but should be 58-58-126
Yellow- 178-178-88 but should be 180-180-88
Magenta - 156-77-156 but should be 156-80-156


With respect, Andrei.

There seems to be a discrepancy between what CalMAN requests from the pattern generator and those "should be" numbers. I just double checked the triplet numbers against CalMAN. More info would be required to see if we can get to the bottom of this.

If You want to make BD ISO from the patterns, You should use .m2ts files as source to have no conversions that may cause changing the RGB levels. And You should verify by doing back conversion to picture files to see if the RGB levels are correct. We may can make a deal of it. If Chad has finalized his patterns, 8bit targa format appreciated using 8bit RGB as preset in software, I can convert to m2ts and one of You can master the ISO. I noticed some of the patterns I converted for chunon a wrong preset was used and had to be corrected by myself. Making correct BD ISO (with menu) from picture files is not as simple as some might believe.

Chad,

I was just looking at the contrast pattern. For me to be able to see all 3 bars in full without losing any of the corners on them, I have to set my contrast at 76 out of 100. On almost all of the calibration sites for my LG TV, places like Cnet and others have contrast at 90.

Am I reading the pattern correct and we are to be able to see the full bar and not lose a corner to the backgraound?

It may be the local dimming. LD on may need a lower contrast setting than LD off.
Also, from the way you are wording it I am not sure you're if you are using it correctly. The idea is that with a flat panel (non-CRT) you should adjust the contrast so you can still see the whitest strip in the middle of the bright box. The bright box is at 235 (100%), the whitest strip at 245. Then there are two strips just slightly darker (98%). If the whitest strip becomes compressed or starts to blend into the bright box, that means you are compressing or clipping WTW. Depending on your calibration philosophy, you may want to keep the contrast below the point where that becomes apparent.
If the slightly darker strips (98%) start to blend in as well or disappear, you are clipping actual video white and definitely should back the contrast down.

Ok.

I will have another look at it. From what i remember when I looked last night, I could turn my contrast up some more and still see the WTW bar, but I do seem to lose the 2 98% bars. Seems like that shouldn't happen in that order though. The LD on the LG does make a big difference on all patterns and measures. I think at this point, I am going to leave it on high the whole way through my next calibration and see what results I get. Turning it off for measures and then back on after has big differences. I think that may be coming into play on these patterns too.

I know from the contrast pattern that I should hit the point right before I lose WTW and still be able to see the 98% bars, but my TV is not playing nice with it for some reason.

Would be nice if this could be master by the same person that did the 709 disk as that seems to work in most all players these days.

did you just burn the iso to a dvd, or did you use imageburn and burn the dvd from the iso image?

when you look at the dvd in explorer, do you see one file "chads.iso" or directories "BDVM" and "HDAVCTN"?
