View Full Version : HCFR v2.01 takes 0-100IRE readings but no longer graphs all results!?

I'm very confused. Been using HCFR v2.01 for a few days and and love it, but all of sudden it's no longer creating same of the nice graphs after I take my 0-100IRE readings. The Color Temp and CIE diagrams show up, but the ones I really care about: Luminance and RGB Levels are blank!

Steps/screenshots:

1. I start HCFR v2.01 click File -> New (DVD manual, Spyder2).
2. Click on "Measure Greyscale" button and go through the 0-100 IRE steps.
3. HCFR then displays my results correctly (see below):

(Not a perfect greyscale... still working on it...) :)

4. I click on the various graph icons in the top toolbar to have HCFR graph things out but not all of them show results like they used to! They used to all work but for a couple of days now I only get blank graphs like the one below for Luminance and RGB levels (RGB levels shown as an example):

HCFR *is* capturing all the data it needs so why isn't it calculating the graphs? This one has me very confused. Did I set click something non-o
obvious by mistake? It used to work just fine! No idea what I did...

Any help would be appreciated! Thanks!

That's odd. I've never seen that.

Sometimes when things disappear in the graphs it's because the colour depth on the computer running HCFR has been set to 16 bit instead of 32 bit. Did you check that?

It's always been 32 bit. I can pull up older graphs that I did in previous days and they look fine beside newer ones which are blank.

But here's something odd - When I display the newer blank readings in a window and also load an older version beside it, the graphs in the OLDER window also show up in the NEW window when I toggle on the "reference" checkbox on the OLDER window:

The older one is the one the right. The newer one is on the left. The graph of the older reading shows up in the newer window when I toggle the "Reference" checkbox on in the old window. The two graphs shouldn't look the same at all. I can't get the new data to show up at all.

I'm perplexed. Though I admit I don't understand what this reference stuff is about... but I would assume if I load the app new, take new readings, that it should graph. No?

I re-installed HCFR 2.0.1 but the problem still happens with files I've saved in the last few days. Before that the files look fine.

Does someone mind trying it in HCFR 2? Attached is my zipped HCFR file.

I think I figured out the problem.

The 0% entry in the greyscale readings is empty. I turned on editable data and just copied over the 10% data into the 0% column and that brought back the graphs.

I looked at my other files that had worked and they all had 0/0/0 for x/y/Y in the 0 IRE slot so I did the same for 0 IRE and all is well!

Excellent! Thank you very much! Now to get to work on the 0-50 IRE range which isn't flat... :)

1. You should always get a 0% reading. Copying the info from 10% will make it so you are displaying incorrect gamma. If you are reading a 0% window and not getting any results at all from HCFR, try a new driver for your spyder and see if that helps.

2. What kind of TV are you trying to calibrate? Make/Model

It's a Zenith 1200 CRT projector (rebranded limited edition Barco Cine 8 Onyx).
See: http://www.hometheaterhifi.com/volume_8_4/zenith-pro-1200x-projector-11-2001.html

The times it did work at 0 IRE it would get readings of 0 for xyY. Entering all zero's for the the 3 gets me the same gamma result (2.21 or so).

I seem to get no readings at times from the Spyder2 when the signal is too low to read - as it is at 0 IRE as the screen is completely and truly black because it's a CRT project (ie: you cannot see your hand in front of your face at all and my HT is cave-like at night).

Do you have the Spyder properties in HCFR to take longer readings for lower IRE's? Might try turning that on too if you don't have that on already. So long as it was reading 0/0/0 I reckon that'll work. Calibrating towards screen or towards proj?

kal, as nichol mentioned, you may want to try turning on the "average many readings for dark measurements" as well as the "extend read time on dark measurements" and see if that helps with readings at the low end.

cheers,
