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

I used imageburn to burn the DVD from the ios. Looking at the DVD it has directories. It plays, but not correctly in a samsung player but not the pany 210.

Vega,

With my Samsung P2500 player I cannot navigate the main menu. The top level works fine but I cannot move down to the other sub-menus. This player works fine with the AVS HD 709 and the GCD disks which were burned with ImgBurn as was your iso download. Granted that the P2500 is pretty old but it still contains one of the better processors. Haven't yet tried it on the newer Sony BD player in the bedroom.

Looking at the resulting new DVD burned from your iso, all the directories and files on the new disk are where they should be.

vega509 is using Multi-AVCHD, which is the same program I used for the AVCHD compatibility. The program appears to have only been updated once, so I doubt much has changed. Assuming you can play the AVS HD 709 AVCHD version on the player, I would guess there could be one of two issues. Some players seem to play or not play AVCHD depending if the BDMV/AUXDATA folder is included, and I think there are a couple options for how Multi-AVCHD outputs AVCHD. Since Blu-ray includes the AUXDATA folder and AVCHD doesn't need it, we simply host two versions. I did a quick modification to the files from vega509 and threw out all the folders that I didn't include on the AVS HD 709 AVCHD download. You will need a program like 7-zip to decompress http://www.filedropper.com/chads-repack_1 (choose "Download This File")

Edit: Removed part of post since he said that the disc was authored with strict option. If the above link doesn't work it might be a Multi-AVCHD issue. I can't think of other possible causes.

For some reason I think Multi-AVCHD has a couple AVCHD output options, and maybe it needs the AVCHD-strict option. Google returns the following:

I authored in strict mode, without it both my Panasonic, and my Denon had problems with the disk.

I've re-authored the disk adding the new 75% patterns, and added the GCD color checker patterns. If anyone is interested, let me know where to upload it to.

Not yet - having a nightmare - got 3 months off work which is giving me alot of time to mess around with various patterns but to be honest im starting to think its a compete waste of time in respect of gamma given the varying degree of results and nothing really to reference it against. Ill try Chads patterns tomorrow and see how I get on.

Hi Vega,

Can i ask what size windows youve used for the colour checkers? Are they 1% APL's? If so what level background did you use?

Cheers

Chad, how did you find the gamma tracking using 5% windows? Did you have to make many 10pt G adjustments to get it linear?
Ive made quite a few custom patterns myself but im still bugged that the current patterns i use (1%) goes against the grain in terms what actually represents real life content so probably like others, in a tight spot with many opinions as to what patterns should and shouldnt be used.

these are the 1% patterns from the GCD disk. The spreadsheet by zoyd GCD_targets_v13.xlsx is where to check the readings from this disc.

Since I don't have a plasma I have not been participating in the gamma discussion but have kept up a little with the threads. It seems to me and of course not being able to see the finished result it is just a logical guess, if the 1% pattern allow you to set a flat gamma without the ABL kicking in, wouldn't that be the way to go? I mean there is no way to defeat the ABL so wouldn't that give you the best you can hope for with ABL? Then again if the manufacture has set the default to a non flat curve so it works with the ABL (hard to imagine) it could be detrimental...

Chads Patterns Version 2 AVCHD ISO

this downloads with the extension .ios NOT .iso

do I need to change it to .iso to be able to burn it to a DVD successfully?

Sorry, just rename it if you have downloaded it.. fixing it now.

How did you know that the color calibration needed Panasonic VT30 pattern 55% or 65% luma and 100% sat ?

and what will be the best for Panasonic VT50 ?

75 luma\ 75 sat ?
or other?


With great respect, Andrei.

With great respect, Andrei.
Prior to the luminance FW fix, a color measurement of 55% luma agreed much better with how familiar program material looked than 75% luma patterns. After the luma FW fix, I felt slightly lower than 75% luma patterns were still ideal, though it was not nearly as critical and 75% could be used effectively. Reduced saturation measurements were not available back then with my chosen software/hardware combination.
For the VT50, I recommend 75% sat/75% luma gamut calibration using approx 5% size 18-25% APL windows.
post #142 of 165
A huge thank you!!!

What should be the level of AL ? 13% ? or other?

Anta brings up a good question.

When do you know to use a different Luma pattern? Does it just not look right to your trained eye??

This article explains it fairly well.. you have to do sweeps and compare the results.. every display is different.

Anyone use the new iso and can verify that everything matches up (ie.rgb levels,luminance) since there was a couple of conversions .png>mp4>iso to get to the iso.Thanks
post #146 of 165
I somehow missed this thread. This forum is getting crazy with calibration discs! Which to use or use them all lol. Thanks for putting this out there chad. I'd previously been using the 10% windows for my vt50 off GCD but am interested in trying the 5 % or so non apl windows you have.
post #147 of 165
Just created the DVD-R with imgburn, thanks again guys. Works great with my Oppo, cant wait try out the Grayscale and Gamut circles with the VT50 this weekend.

Just a side note: whenever there was a rounding question, I matched to CalMAN's V5's required triplet.
post #149 of 165
Thanks chad. Since I'm not too up on the "triplet" part of it, do you see an issue with me using your 4% patterns for my vt50, 30-100% stimulus with calman 5 and the i1 pro 2. I'd then use your 10 and 20% with the d3 pro and ChromaPure? I figure I could run 30-100 in ChromaPure with the d3 and see how it is off compared to the i1 pro 2, and use that knowledge for what 10-20 looks like?

Thanks.

I guess one other question is why wouldnt everyone use the same triplets in their software calculations and patterns? It seems from my reading that ChromaPure and calman vary here.

I put in a question to Tom in the CP thread to see if the triplets I use here will give correct results with ChromaPure.
