To enable custom metadata export, you'll create a configuration file named customMetadataExport.json in the following folder:

1. Close Catalyst Prepare.

2. Using a text editor, create your configuration file. The file should be structured like the following example to include the key, value pairs that you want to make available as custom metadata. The key is the metadata item, and the value will be used as the default value:
   
   {
   "Slug": "Election",
   "Type":"News",
   "Source": "",
   "Shot Date": ""
   }

3. Save the file in the following folder:

   Windows: C:\Users\<user>\Documents\Sony\Catalyst\

   macOS: /Users/<user>/Documents/Sony/Catalyst

4. Start Catalyst Prepare. The application will detect the customMetadataExport.json file during startup and enable custom metadata export.

1. Select the clips you want to export in Organize or Edit mode.

   The left pane allows you to navigate the folders in your library, and the middle pane displays the contents of the selected folder

   • Click a file to select it.

   • Hold Shift and click the first and last file you want to select to select a range of files.

   • Hold Ctrl (Windows) or ⌘ (macOS) to select multiple files.

     Click the Select button to select multiple files without using keyboard modifiers.

2. Click the Export button at the top of the Catalyst Prepare window.

3. Enable the Use advanced settings switch in the Export pane.

4. Select the Add custom metadata check box. An edit box is displayed for each metadata item you defined in your customMetadataExport.json file.

   Type the desired value for each metadata item that you want to include for the rendered file. Custom metadata is saved in a sidecar .json file.

   Use the controls in the Export pane to choose a destination and format for your exported file. For more information about the controls, please see "Exporting media from a library.".

   If the customMetadataExport.json file is empty or incorrectly formatted, the Add custom metadata check box is unavailable. Please see "Defining the metadata you want to export."
