Learn how to enable writing of metadata in a channel's output files.
Enabling writing of metadata to output files
Where: Channel | Metadata | General tab
In the General Options group, make sure that the Save Metadata with Output File option is selected if you want to preserve or add metadata in output files. If you would like to strip the file of all metadata, deselect the option.
Note that if the Metadata feature isn’t enabled for a channel, metadata will be preserved by default.
Tip: To remove unwanted metadata from processed files, try using Metadata Filters.
