Request params

Field	Type	Required	Description
`content_type`	string	Yes	MIME type of the mixed media file (case-insensitive). See Supported `content_type` values below.
`total_bytes`	integer	Yes	Size of the file in bytes. Must not exceed the file size limit.

Supported `content_type` values

Mixed media accepts standard video formats plus GIF:

MIME type	Format
`video/mp4`	MP4
`video/webm`	WebM
`video/quicktime`	MOV
`video/x-matroska`	MKV
`video/avi`	AVI
`image/gif`	GIF

Other image types (for example image/png) are not accepted.

File size limit

The maximum upload size is the same as for videos (MAX_VIDEO_BYTES, configured per environment). If the file exceeds this limit, the API returns 412 with:

Max file bytes size: {MAX_VIDEO_BYTES}

Response `201 Created`

Field	Type	Description
`resumable_url`	string	Google Cloud Storage resumable upload URL. Upload the file with HTTP `PUT` to this URL before starting prediction.
`media_id`	string (UUID)	Identifier of the created mixed media object. Use this in later calls (predict, AOIs, objectives, impact score, etc.).

Example request

{
  "content_type": "video/mp4",
  "total_bytes": 953311
}

GIF example:

{
  "content_type": "image/gif",
  "total_bytes": 512000
}

Example response

{
  "resumable_url": "https://storage.googleapis.com/...",
  "media_id": "036d5cb3-4fb1-4e88-98e6-1854b607d296"
}

Typical workflow

Create mixed media — POST /predict/v2/mixed-media. You receive media_id and resumable_url.
Upload the file — PUT the binary to resumable_url.
Predict mixed media — PUT /predict/v2/mixed-media/{media_id}/predict.
Poll media status — GET /predict/v2/media/{media_id} until prediction status is done.
Optionally configure objectives, AOIs, benchmark ranges, and impact score via the shared Media endpoints.
