Use the LUT Editor to convert logarithmic images to linear images or linear images to logarithmic images, while maintaining color accuracy.
To access the LUT Editor menu, use:
Batch, then select a node from the Node bin.
Timeline, then add Timeline FX from the Effects ribbon (see Adding Timeline FX).
Timeline, then use Batch FX (see Creating Batch FX).
Tools, then select from the menu (See Accessing Tools).
The Modular Keyer, then select a node from the Node bin.
This node accepts a front clip, and outputs a result.
The LUT Editor node can also be used to apply a conversion to 16-bit floating-point image in the OpenEXR file format.
When you import or export clips in Batch, default LUT parameters are used and the direction of the conversion is detected automatically. Use the LUT Editor to modify these default settings interactively or to import an existing LUT. You can also export a LUT from the LUT Editor.
When you load an OpenEXR-formatted clip into Batch, you cannot connect it directly to nodes that do not support 16-bit floating-point images. To work with a node that does not support this input, first connect the clip to a LUT Editor node to convert the clip into an 8- or 12-bit linear image. Whether or not you change the clip's bit depth, use the LUT Editor's EXR Display option to control the image's luminance and black point properties.
The LUT Editor node can be set to output a bit-depth of 8, 10, 12, or 16 bits. You can also manually set the variables for output. When accessing the LUT Editor as a Timeline FX, you are not able to perform bit-depth conversion.
