Hi. after the colorspace conversion, VideoScale filter (with Pass Black or with Clip Black) is the last step you do before exporting the cLUT to eeColor65.TXT format.
For eeColor users, once they have generate the correction 3D LUT Table, the last step before exporting the cLUT to eeColor 65.TXT format, it's to apply the VideoScale filter.
We do this for eeColor because eeColor's internal 10-bit table is 0-255, the videoscale is mapping the correction to 16-235 levels, since we will use it for HT enviroment / blu-ray content etc.
The VideoScale is not required for Lumagen users because it's internal 10-bit table can control video levels (16-235) only.
LightSpace has 2 options about VideoScale Filter:
VideoScale with passblack and VideoScale with clip black.
The VideoScale with Pass Black is mapping the levels from 0-255 to 16-235 and later it applies a UNITY to 0-16 levels. so all below black information is visible.
The VideoScale with Clipping Black is mapping the levels from 0-255 to 16-235 and later and all the 0-16 levels are becoming 16. so all below black information is becoming 16, no below black information is visible.
One scenario where VideoScale with Clipping Black is helpful is when we have a display which it's difficult to set with success it's near black with a brightness with flashing bars pattern using the display's internal brightness control setting.
For example lets say we have a display...when we display a brightness pattern with flashing bars, we don't see 17,18 flashing bars with internal brightness setting at zero....
but when we use +1 brightness, we see 17,18 flashing bars correctly but we see the 15 and 16 flashing also.
In that case when we will apply VideoScale with Clipping Black, the 16 and below bars (15,14 etc) will become 16 also, so we will be able to see correctly see the near black details of 17,18 levels to that specific display.
To export the correction file in eeColor 65-Point format click: File -> Export -> Tick only the [3D] eeColor65 (*.TXT) and click Export. It will ask you for a folder, you can select your Desktop for example.
Locate that TXT file and rename it to 3DLUT_1.txt if you want to be uploaded to Slot 1 of your eeColor.
After that you will use the TruVue eeColor Application Software (You can download it from here: http://www.displaycalibrations.com/f..._Version_2.zip
) to upload the 3D LUT table to eeColor memory.
You have to paste that 3DLUT_1.txt file to the TruVue eeColor Application Software installation directory: ''C:\Program Files\Entertainment Experience LLC\TruVue eeColor Application\Data\3dtable\standard nonrgb led\General Media''
Here you can see where you have to click upload custom 3D LUT correction table to eeColor:
You can create to your desktop a shortcut that will bring you very quick the correct folder to place there the custom eeColor TXT files.
(you can browse for custom icon and load one of the eeColor DownLoadTable.exe files you see inside the TruVue eeColor Application directory to bring you an eeColor icon for that shortcut)
As destination for that shortcut (for my Windows 7 64bit) is: "C:\Program Files (x86)\Entertainment Experience LLC\TruVue eeColor Application\Data\3dtable\standard nonrgb led\General Media"
