Media type name: video

Media subtype name: prs.avid

Required parameters: N/A

Optional parameters: encoding: underlying codec (e.g., "h264", "vp9")
version: AVID format version (e.g., "1")

Encoding considerations: binary

Security considerations: This media type defines a binary container for video content and AI provenance metadata.

No executable content is included, but embedded video streams must be treated as untrusted input.

AVID supports integrity verification via cryptographic hashes and may support digital signatures in future revisions.

Metadata may include model information, timestamps, and content fingerprints. Sensitive metadata should be handled carefully or excluded.

If embedding standard video formats (e.g., MP4), their respective security considerations apply.

Secure transmission is recommended.

Interoperability considerations: AVID supports compatibility with existing video ecosystems by allowing standard video streams to be embedded.

Legacy systems may still decode the video portion while ignoring AIMG metadata.

Full interoperability requires compliant parsing of the AVID container structure.

Published specification: https://github.com/aimediaformat/media-engine/blob/main/spec/ai-media-format.md
