Metadata Dictionary and Forms preferences provide options to allow you to load custom metadata dictionaries and html templates for adding metadata to files.
Typically custom dictionaries add the ability to interpret specific metadata schemas. Use the Add button to select a new dictionary.
Metadata forms can be created in Diffuser to add metadata into an MXF file. Browse to select forms to add metadata to either the overall clip file, or at a specific time point in the clip. See Diffuser for more information about these forms.
