JSON File Structure

Each JSON file contains array of per-frame annotation data:

  • The first element in the array (β€œzero frame”) contains general metadata, while the rest of the elements contain data for frames 1...N (where N is the last frame).

  • The length of the root array is therefore N+1 elements.


{Zero frame object},
{Object for frame 1},
{Object for frame 2},
{Object for the last frame}
