Once the videoannotation task is done, we will send a response to your callback URL. The response.annotations.url field of the callback will be a link to a JSON file containing the annotations.
{
"response": {
"annotations": {
"url": "https://scaleapi-results.s3.amazonaws.com/5e5dc4a0-1d9b-11e8-bce8-41122de76217"
}
},
"task_id": "",
"task": { ... }
}
The annotation file will contain a list of AnnotationFrame objects, one for each frame of the videoannotation task. The AnnotationFrame objects will be in temporal order; that is, the first AnnotationFrame will correspond to the first frame in the videoannotation task's attachments array, etc. Each AnnotationFrame is a list of Annotation objects - reference the documentation for each geometry (Points, Lines, Boxes, Ellipses, Cuboids, Polygons) for the exact schema.
