FYI, you can update that the Sony PS3 (fat) will play the HDMV ISO burned to a DVDM. It just worked great for me.

Ran through the whole thing, on mac. I wonder if the order is different or something, because it's hard hard to jump around when running through the mac version of Color HCFR. Still found everything eventually though. Turns out my display isn't too bad, just a little low on red and high on green. the tint slider should help that.

I'll wait to see if anyone else reports that the PS3 can now play the HDMV download from DVD media. Previous firmware versions for U.S. players were unable to do this.

I received a note from DFrost about a mistake for the luma value stated on page 14 in the PDF. The number has been corrected. I also reread the PDF and made a few other very minor changes. Since no one has reported issues with the PDF download from Dropbox, I did not upload the revised PDF to the w6rz mirror.

Okay, I literally have no idea what I'm doing. I downloaded the MP4 (.exe) set of patterns and proceeded to try and burn them to a disc as per instructions. I did so to the best of my ability, but when it shows on the Xbox dashboard the disc is called "Mixed Media Disc" and won't play? What did I do wrong?

I'll assume you can play the video files from the disc using your computer. By default the Xbox cannot play the MP4 video. If the Xbox is connected to the internet it should ask something about updating when you try to play the video for the first time.

The Xbox 360 should be able to play MP4 video after the codec update. From what I remember, I think the general steps at the top of the following link are how you can play video clips from a burned disc http://www.ehow.com/how_6868844_play...-xbox-360.html

that's fine, probably best to check with others. But I burned the ISO with Imgburn on my PC. Plays perfectly, great test.

I'm trying to calibrate my Samsung LN46B750 using the AVS HD 709 patterns, an eye 1LT colorimeter, and the HCFR program, but I keep getting stuck at tint and color control.

When I use "blue-mode" I can calibrate the tint and color according to what is visually right, but when I use the HCFR dummies guide to check it and change it according to my readings, my blue-mode tint and color are off.

Should I calibrate in blue-mode and then do the primary and secondary color scales after? or what?

Thanks

Burn from PC and works on my PS3. But I don't know what I'm doing..
I just purchase the 55 D8k. a newbie to calibration. I guess reading the manual will help.

I have read statements that basically say the same thing, but I still haven't seen anyone post color measurements after they used blue mode for setting color and tint. If I had a TV with a blue mode, what I would do is start by setting color and tint using the blue mode, and then I would measure both a large and small APL series. The APL series just eliminates any possible brightness change from the TV that could potentially affect measurements, and measuring both series simply gives an idea how much measurements vary. If you want to take measurements for two color runs, they can be put in a zip file and attached to a reply. Without seeing measurements, I can't really comment.

could you explain which series this would be? I'm still trying to figure out all the terms, so if you could refer me to a section of the dummies guide or tell me what patterns i should use to do this, I will measure it and post my results. Thanks

Step 8.4 from the guide deals with measuring color. The measurement patterns here are offered in Windows, Fields, and APL versions. You would need to use the ColorHCFR APL measurement patterns, and choose the Small 75% Color video. After you have taken a measurement run, save the color measurements to a file. Then take another measurement run with the ColorHCFR APL patterns, this time choose the Large 75% Colors, and again save the file after taking measurements.

Ok, I attached a zip file with my 75% APL readings from small and large patterns. I'm not really sure what I'm looking for so any help would be appreciated.

Note: These are the readings with BLUE MODE calibration and color scale set to auto(default).

also, should i be using the 75% or 100% modes for calibrating? because I thought it said to use the 100%? and should I be doing greyscale this way also?

If you haven't done so already, I would probably switch to the "HDTV - REC 709" reference (see step 1.5 from the guide). When you are at the main screen (measures tab), look to the left of the sensors area and you should see a couple arrows. If you click the down arrow to the right of the "Editable data" text a few times you should uncover a "delta luma" line. The delta luma line compares your relative Y measures against the reference.

The delta luma line says that your blue lightness (brightness) is dead on, which is about what I would have expected from a blue mode. The delta luma line says that brightness for green is also very good. The delta luma line reports red as too bright in comparison to white. If your TV has CMS type of color controls you may be able to reduce red lightness to bring it more in line with the reference. Personally I would probably see if there's a way to get red luma to measure closer to zero, but that's about it.

If you view the CIE diagram your measures don't line up perfectly with Rec 709, but they're not bad. Green and red are inside the reference triangle (undersaturated), yet the hue (angle) of red and green are good. This might just be how either the TV or meter performs. If you haven't already made changes that moved red and green in toward white, or if the TV doesn't offer a setting with wider primaries, there probably isn't a way to move red and green xy position closer to the reference. Maybe blue could be rotated (blue hue adjustment) a bit counter clockwise, but really blue is about as close to reference as can be expected. I'm not familiar with the TV or exactly what color controls Samsung includes, but generally I thought the CIE diagram was very reasonable.

I'm not sure what you mean by modes. I'll assume you meant 75% or 100% color patterns. On these patterns the percentage is usually shorthand to mean percent stimulus. Really the 75% Colors could be said to be 75% Stimulus Colors. The reason I suggested using 75% stimulus colors is because color bars for use with a blue mode usually also have 75% stimulus colors. Anyway, my main point is that using 75% is perfectly fine, and generally that's what I look at first.

Personally I think the "Terminology" and "Adjusting Color using a Color Management System (CMS)" sections from http://www.avsforum.com/avs-vb/showthread.php?t=852536 would be useful to understand if you are going to be adjusting a CMS. I'm sure it took me a while to understand what he's saying there, so at minimum it would probably take multiple reads. Basically the main idea is to get the delta luma line (brightness) of the colors close to zero, and try to get as close as you can to the reference points on the CIE diagram.

Download the Patterns Manual from the first post and you will know what to do after studying it.

I haven't looked at the THQ pattern. The first level above black on the Digital Video Essentials pattern is higher than 17, so with Digital Video Essentials it is possible to use a lower brightness. If you use the lower setting you may lose a bit of information above black, and generally I don't think it makes sense to cut off dark gray information.

I downloaded the avchd.7z file and I could calibrate my tv using ps3 fat as source. Firmware version is 3.61.

I also could calibrate another tv using sony bdp-s270 as source with same disc.

Thank you for the amazing work you've done here.

I'll try the hdmv version this weekend.

The download should be 625,325,484 bytes (see Download Note B). The download should decompress to an AVCHD-2d.iso file of 4,692,443,136 bytes (see Download Note A). I recommend using ImgBurn (see Example for Windows Computers).

A few people have reported issues with the .exe, and in that case the .7z is recommended.
