Create object-tracking video task

API Reference

Track 1–64 selected objects through the uploaded source video to produce an aligned mask video.

Submit objects as a JSON-encoded array in a multipart form field. Each object requires a box in source-video pixels, ordered [x1, y1, x2, y2]; optionally include mask, a base64-encoded binary mask within that box (0 for background, 255 for foreground), for more precise selection.

Example objects (box only): [{"box":[455,85,700,544]}].

Example with a more precise mask:

[
  {
    "box": [455, 85, 700, 544],
    "mask": "iVBORw0KGgoAAAA..."
  }
]

The mask string above is abbreviated; supply the full base64-encoded mask.
