One way to begin creating a custom LUT using the LUT Editor is by defining the type of LUT you want to use. You can choose from one of the presets for converting logarithmic data to linear data, linear to logarithmic, or for creating a LUT to manipulate images that are already linear. Each of these selections sets up the appropriate conversion curve. It also includes selecting a bit-depth for the output. Alternatively, you can also choose to import a LUT as a starting point. Each of these techniques is discussed in this section.

Another way to create a custom LUT is to load a LUT Editor setup. See Loading LUT Editor Setups.

To select a basic LUT type preset:

1. From the Conversion LUT Type box in the LUT Editor, select an option.

   
   

   Select:	To:
   Log to Lin	Begin with a standard curve for converting logarithmic data to linear data.
   Lin to Log	Begin with a standard curve for converting linear data to logarithmic data.
   Gamma	Begin with a standard curve for modifying linear data.
   Import	Import a LUT to use its curve as a basic LUT. See the following procedure.
   3D LUT	Import a 3D LUT. See Processing Clips with 3D LUTs.

   The conversion curves for the basic LUT type you selected appear in the LUT Editor as the basic LUT.

2. Select an output bit-depth option from the Destination box. You can output 8 bits or 12 bits per channel.

   
   

To import a LUT to use its curve as a basic LUT:

1. Select Import from the Conversion LUT Type box.

   
   

2. Click Import.

   The file browser appears.

3. Locate and select the LUT that you want to import.

   You are returned to the LUT Editor.

   The LUT name appears in the field below the Import button. The imported LUT's conversion curves appear in the LUT Editor as the basic LUT.

   NoteWhen you import a LUT, advanced setting are merged into the basic setting. In order to access the settings used to create a LUT, you must load the LUT, not import it. See Loading LUT Editor Setups.
