Unknown frame id for the submission of future hand prediction challenge

I created the same issue here, but I will share here as well.

According to the submission guidelines of future hand prediction challenge, the submission format should be a .json file with following format:

  {"ClipId1_FrameId1": 
  [p3_left_hand_x, p3_left_hand_y, p3_right_hand_x, p3_right_hand_y,
  p2_left_hand_x, p2_left_hand_y, p2_right_hand_x, p2_right_hand_y,
  p1_left_hand_x, p1_left_hand_y, p1_right_hand_x, p1_right_hand_y, 
  p_left_hand_x, p_left_hand_y, p_right_hand_x, p_right_hand_y, 
  c_left_hand_x, c_left_hand_y, c_right_hand_x, c_right_hand_y], 

  "ClipId1_FrameId2": 
  [p3_left_hand_x, p3_left_hand_y, p3_right_hand_x, p3_right_hand_y,
  p2_left_hand_x, p2_left_hand_y, p2_right_hand_x, p2_right_hand_y,
  p1_left_hand_x, p1_left_hand_y, p1_right_hand_x, p1_right_hand_y, 
  p_left_hand_x, p_left_hand_y, p_right_hand_x, p_right_hand_y, 
  c_left_hand_x, c_left_hand_y, c_right_hand_x, c_right_hand_y], 
  
  ...
  }

However, we only know clip_id, clip_uid, and, video_uid for test data:

{
  "version": "1",
  "date": "220217",
  "description": "FHO Hands & Objects",
  "manifest": "s3://ego4d-consortium-sharing/public/v1/full_scale/manifest.csv",
  "split": "test",
  "clips": [
    {
      "clip_id": 3,
      "clip_uid": "de4a85e5-1809-4547-ae11-9161aa9fdbe9",
      "video_uid": "31ea56e6-7a99-4b91-b74b-3b1e6de05e99"
    },
    {
      "clip_id": 2056,
      "clip_uid": "83acc738-4435-451d-a38f-2a3a6cd85879",
      "video_uid": "4ce9f93b-f44c-46fe-9050-3452d2f39abb"
    },
    {
      "clip_id": 10,
      "clip_uid": "bd5e0084-7bf1-4e34-abba-cc3f6a370213",
      "video_uid": "cde41c4f-50d1-4910-9f2a-4c7b6987df92"
    },
...
}

Then, I would like to know how can we know which frame is corresponding to the last observable frame (one frame before pre45 frame)?

We are reviewing this problem and will come back shortly. Sorry for the inconvenience.
