When working on a project, it may happen that the matte media files located in matte and multimattes folder are modifed (edited, added or deleted). In this case, Lustre can synchronize the cut or grade file and the source clips with the external matte files.
To synchronize the cut or grade file and source clips with the external matte files:
Lustre synchronizes the shots in the Timeline and the clips in the Library with the content of the matte / multimattes folders. It then updates the clips, converting them to multi-channel when mattes are present or leaving them as single-channel when no mattes are found.
