Saving Timeline RGB Offsets
 
 
 

You can save the grade for the entire timeline in a file called primary.txt. This file is similar to the .dsc file, except that the information is timeline-based as opposed to folder-based and cannot be loaded back into Lustre. The benefit of saving timeline RGB offsets is that you can exchange primary grading data with other systems.

The following is an example of what the primary.txt file looks like:

GRAO 2

46928774000050 <HOME>/2k/dpx/2048x1556/008_%05d.dpx -64.457 80.586 -16.129

46928774000052 <HOME>/2k/dpx/2048x1556/009_%05d.dpx*-52.922 84.429 -31.507

To save the grade for the timeline:

  1. Press Shift+G.

    The primary.txt file is generated in the Lustre export directory, e.g. C:\Program Files\Autodesk\Lustre 2009.1\export on Windows, and /usr/autodesk/lustre_2009.1/export on Linux.

The Shift+G hotkey has another function. In addition to saving the primary grading data for the timeline, the hotkey automatically runs batch scripts. This could be used, for example, by a facility to convert the grading data to a LUT or third-party Color Decision List (CDL).

To automatically run a batch script:

  1. Create a batch script called primexport.bat.
  2. Place primexport.bat in the C:\Program Files\Autodesk\Lustre 2009.1\export directory on Windows, and /usr/autodesk/lustre_2009.1/export on Linux.
  3. Press Shift+G.

    Lustre saves the primary offset RGB values for the timeline in the primary.txt file, and automatically runs the batch script.
