Applying 3D LUTs
 
 
 

When you use 3D LUTs, you apply an interactive viewing LUT that works through the NVIDIA® graphics card. The 3D LUT displays how the colour graded images will look on film stock as you work, without impeding processing speed.

The 3D LUT is a LUT that can also be applied to the video output (such as a preview monitor). Use the 3D LUT when you want to view your work on a video monitor—the 3D LUT will simulate one destination medium on another medium on output. For example, if you want to create a particular film look when you output your colour graded shots to video, you can simulate the film stock on video by selecting a 3D LUT. Finally, you can apply up to three 3D LUTs on the same image for viewing in the Input LUT, Calibrate, and Render Output menus.

TipTo output the colour grade with the 3D LUT to video, render the images with Render Local Viewing enabled. The 3D LUT will be included in the render without slowing down playback speed.

To apply a 3D LUT:

  1. Save the 3D LUTs in the C:\Program Files\Autodesk\Lustre 2009.1\lut folder if running the Windows version of Lustre, or in the /usr/autodesk/lustre_2009.1/lut directory if running the Linux version of Lustre.
  2. In the Calibrate menu, click Off to disable existing monitor calibration settings.

    TipIf you copied or saved a 3D LUT to the lut folder but the 3D LUT is not listed, press CTRL+R to refresh the Print LUT list.

    The selected 3D LUT is assigned to L1.

  5. Repeat steps 3 and 4 to assign 3D LUTs to L2 and L3.
TipFor real-time playback with a 3D LUT applied, enable GPU acceleration by clicking the GPU button or pressing Y. Lustre supports trilinear interpolation in 3D LUTs on both CPU and GPU. See GPU Acceleration.
