In order to upload a video to be calibrated, go to the "Video Management" option in the top menu and click "Upload Video." You'll be taken to a screen with a number of fields that need to be filled out. Enter in the requisite data for the video, and then click "Save Data."
Once you click "Save Data", an upload field will appear in the lower left corner of the page. Click "Choose File", find the desired video, and then click the "Upload" button that appears.
Note: You must remain on this page until the video upload has reached 100%
