Media types in Drupal are similar to content types. They are designed to capture and manage important information about each media asset through customizable fields. These fields enable you to store a wide range of metadata and details that enhance the organization, accessibility, and usability of your media library. For example, you can use fields on media entities for alt text, captions, credits, or licensing information.

Acquia Source includes the following default media types:

• Image
• Document
• Remote Video
• Video
