# Cast media schema

> Supported in:

Casts a media reference to a specific media schema and format. This is useful when the input media has a generic schema (multimodal) but the actual content is known to be a specific type (such as a png image). The cast narrows the type metadata to allow downstream operations that require specific schema types.
