Custom Metadata

This page is about valid key-value pairs which can be used within Adobe Premiere Pro + Media Encoder and synced to Cosmo.

In general Adobe is following the default definition of allowed character for xmp.

Key

  • Are case-sensitive

  • Can not start with a number

  • Can not contain underscore (_)

Value

  • Are case-sensitive

  • Can start with a number, contain only numbers, or be a combination of numbers and letters

  • Can contain underscores (_)

Example for metadata key

Metadata key: "key_value pair" This is not valid because there is a underscore in the key name. While values can contain spaces, keys can not.

Metadata key: "1story" This is not valid because the key starts with a number which is forbidden.
