Applying 3D LUTs to the Image Window
 
 
 

To accurately display film clips, you can apply 3D LUTs to the image window, including the reference area and the reference overlay.

3D LUT display in the image window is only supported in modules that also support multiple viewports: Resize, the Colour Corrector (including the Colour Warper), the Modular Keyer, Distort, Batch, and Action. See Previewing Results for Processing Commands and Previewing Results for Format Commands.

When you are working with multiple viewports, you can apply different 3D LUTs to each viewport independently.

To apply a 3D LUT to a clip in the image window:

  1. With a clip in the current viewport set to Front, Back, or Result view, enable Use 3D LUT (Ctrl+Shift+~) to enable 3D LUT display mode.

    The 3D LUT displayed in the 3D LUT list is applied by default to the viewport. Its name appears in the lower-right corner of the viewport.

  2. To change 3D LUTs, do one of the following:

    Press: To apply:
    Ctrl+Shift+1 The first 3D LUT defined in the 3D LUT list.
    Ctrl+Shift+[2-9] The second through ninth 3D LUT defined in the 3D LUT list.
    Ctrl+Shift+0 The tenth 3D LUT defined in the 3D LUT list.
  3. To toggle the current 3D LUT on and off, press its associated hot key (Ctrl+Shift+[1-0]).

    When the 3D LUT is on, its name is in light blue. When it is off, its name is in black.

  4. To disable 3D LUT display mode, press Ctrl+Shift+~.

Applying 3D LUTs to the Reference Area and Overlay

You can enable 3D LUT display mode, and then apply 3D LUTs to the frames displayed when using the reference overlay.

To apply 3D LUTs to the reference overlay:

  1. In the View menu, enable Split Bar to display the overlay in the viewport.
  2. Enable Use 3D LUT display mode for the reference buffer.
  3. Select a LUT from the 3D LUT List box.

  4. To disable 3D LUT display mode for the reference overlay, select Reference Buffer Off option.

Working with Multiple Views and 3D LUTs

When you are working in a module that supports multiple views, you can apply different 3D LUTs to each viewport independently.

To apply 3D LUTs when working with multiple viewports:

  1. Click a viewport to make it current.
  2. Press Ctrl+Shift+~ to enable 3D LUT processing.

    The name of the current 3D LUT appears in the lower-right corner of the current viewport.

    NoteIn cases where a viewport is small, there may not be enough room to display the 3D LUT's name.
  3. Click another viewport to make it current (a yellow border indicates the current viewport).
  4. Select a 3D LUT from the Viewport box, or press Ctrl+Shift+[1-0] to enable the corresponding 3D LUT in the 3D LUT list.
