Imported ILDA file from commercial repository has incorrect colour mapping

In this case the file is in a format that uses color pallets instead of RGB values - this used to be a quite common format many years back, so there is still content around. (There are different versions of the ILDA file standard, as it has evolved over time). You can convert this to the standard RGB format with Showeditor:

1. Open the ILDA file
2. Click: Color Table -> Load Pangolin Color Table - now the colors should display correctly
3. Click: Windows -> Special Features
4. in the window that opens click on the button "Change colors to the HE colortable values"

That's it - if you then export the file as ILDA file again, it will be in the current RGB-values standard, that can also be used with other playback systems.
