When performing a Change Cut, Lustre uses the various Match options to transfer grading decisions from one cut to another. By default, Strict Matching is enabled and the criteria have to match exactly. In some visual effects workflows however, it happens that file names differ between editorial versions even though they're comprised of the same shots. For these cases, you can perform partial matching using the Custom Match option and disabling Strict matching. For example:
The original sequence name is seq1_shot1_version1, while the updated sequence name is seq1_shot1_version2.
The Change Cut is performed based on a Custom / DLEDL Clip name.
The Match is based on partial criteria, and the Partial Match Flag is displayed in the Storyboard.
In this context, you can also specify the number of characters to be compared for a Match to occur, using the slider to the right of the Strict button.
