100% Luminance sweep: Red (Starting @ 0,25,50,75 & 100% saturation) in the following order Red, Green, Blue, Cyan, Magenta, Yellow

Is there any need of a 100% white either before or at the end?

No need for white in the sweeps and the order should be Red, Green, Blue, Yellow, Cyan, Magenta for the sweeps and the color calibration sequence is Red, Green, Blue, Yellow, Cyan, Magenta, White. Thanks!

Yes and for 75% Luminance sweep need 75% white.

I have added a white at the end, so if not needed it should not get in the way.
each pattern will be on for 3 minutes, and if you press next it should take you to the next pattern.

I am using MultiAVCHD to author the ISO (not used it that much) so the menu system will be no ware near the level of the AVS disk, however it should be usable

Chapter 10 will be done in around 10 hours - So if I got time tomorrow I will upload chapter 1 as a beta, so please try it out and comment

Sounds good, are you sure you want 3 minutes/pattern? I typically don't need a pattern up for more than 20 seconds and can hit pause if needed. That would save you considerable rendering time. I think there is a limit to the number of chapter markers in AVCHD format so watch out for that (and no pop-up menus unfortunately) but using chapter skips works fine.

I will reduce the time to 1 minute, the reason for 3 minutes was that I have a profile that defaults to 3 minute for each chapter, but tsMuxeR should be able to create one for each 1 minute

attached is the first beta.

this only contain a 100% luminance saturation sweep
http://gupl.dk/678192/

if there is any comments please let me know.

my plans is:

adding the following
1. 100% luminance saturation sweep [R0,R25,R50,R75,R100, etc.]
2. 75% luminance saturation sweep [R0,R25,R50,R75,R100, etc.]
3. 50% luminance saturation sweep [R0,R25,R50,R75,R100, etc.]
4. 100/100 RGBYCMW
5. 100/75 RGBYCMW
6. 75/100 RGBYCMW
7. 75/75 RGBYCMW

remove unnecessary items in the menu structure
add 1% of all the above but on apl background

others??

75/75/75?

75%amplitude, 75%saturation 75%??

I will look at creating a mp4 version when I have all the encodings done.

Why is the gamma=2.22 but gamma=2.20?

Mastering moniitor standard in US is 2.22. Camera gamma standard is 2.2. I couldn't sleep at night and would consider calibration efforts a complete failure unless I was able to create a custom curve at 2.21 and be able to reach a de with a cheap $400 probe of less than 0.1.

They are related, lightness is a measure of how we perceive luminance.

checking out first beta now.

The first sweep looks great! Easy navigation and nice clean look, very well done. I measured it against the AVSHD 100% sweep and the agreement was very good, luminances are all within 1% and the xy locations all agree to <=0.003 (most < .001)

Please find beta 2.1
http://gupl.dk/678225/

this include
1. 100% luminance saturation sweep [R0,R25,R50,R75,R100, etc.]
2. 75% luminance saturation sweep [R0,R25,R50,R75,R100, etc.]
3. 50% luminance saturation sweep [R0,R25,R50,R75,R100, etc.]

if any problems please let me know.

I will be away with work next week, so a new upload will not available to at the earliest late next week.

Thank you for any comments

beta 2.1 looks good, there is one odd measurement for magenta 50/50 (see attached). This could be my display but 75 and 100 don't show the same behavior. If this shows up in testing on another display type it could be a bad pattern. The curvature in the green saturation tracking is normal for my display.

thank you for letting me know.

the source pattern for 50/50 magenta is correct (as per yourself), however when encoding, something could have gone wrong. But just to eliminate your display please use the attached 2.1.1, this only include the 50/50 magenta, and I have verified that it is correct (by reversing from the video file back to a 24bit TGA file.)

please let me know how it looks

What I meant that the pattern it's correct is that the RGB digital values is as per the excel spreadsheet further up.

Why use magenta 50\\50 in HCFR?
Is it right 50% saturation 100% luminance?

You Can use 50% luminance as long you use a 50% White as reference

Just did some my self and as far as I can see the Magenta 50/50 is ok (Beta 3.0) see attached this is on a Samsung LCD

I am planing on adding the following

100 Saturation - Luminance Sweep (R100%,R75%,R50%,R25% etc....)
75 Saturation - Luminance Sweep (R100%,R75%,R50%,R25% etc....)
50 Saturation - Luminance Sweep (R100%,R75%,R50%,R25% etc....)

Any other patterns needed?

when all pattern is correct and done, I will start working on the 1% APL version
