You can create folder structures that automatically generate Multi-Channel clips and automatically add and sync the matte media located in the matte/multimattes folder to the source clip. If there is a matte/multimattes folder located within the resolution folder of the source media files, Lustre displays the source clip as a Multi-Channel clip.
Note: Grade files created with pre-2012 versions of Lustre and using external mattes are converted to Multi-Channel clips and can be imported in Lustre 2013.
Matte media files must have the following attributes:
- The index (frame numbers), in the source/mattes file names have to match. You can have any number of characters before the frame number value, as long as the frame numbers at the end of the filename match, they will be compatible. For example, shot1_10000.dpx is compatible with 000010000.tif as well as with lustrematte10000.tif.
- The matte media files must be of the same resolution as the clip.
- The mattes must be either RGB or RGBA files.
