Metadata that helps you categorize your videos. You can specify a list of keys and values. Keys must be of type string, and values can be of the following types: string, integer, float or boolean.

NOTES:

• If you want to store other types of data such as objects or arrays, you must convert your data into string values.
• You cannot override any of the predefined metadata (example: duration, width, length, etc) associated with a video.
