When you submit a video to any of Hive’s models (classifier or detector), Hive automatically splits the video into frames based on a default or user-specified sampling frequency. Each frame is then processed by the model, and the results are combined into a single JSON response.

Classifiers will return an array of objects that include a time (timestamp) and classes (confidence scores for each class).

Detectors will return an array of objects that include a time and bounding_poly (for bounding boxes around detected objects).

Synchronous (/sync) vs. Asynchronous (/async) Output Differences

Synchronous (/sync): The output is returned immediately once the video has been processed.

Note: In synchronous mode, you will not see media_link in the JSON response.

Asynchronous (/async): You’ll receive a task reference that you can poll until processing completes.

Note: In asynchronous mode, each frame result may include a media_link to the processed frame, allowing easier retrieval or viewing of the exact image that was classified/detected.
