How to download sproutvideo video

[goken12]

I would like to download videos from my course to do a future review

Link video:
https://videos.sproutvideo.com/embed/7c9adcb01e10eac5f4/8bf7cc07176f8ab7?signature=uKn...636067&type=hd


This method worked, but the course site blocked this method:
https://api-files.sproutvideo.com/file/7c9adcb01e10eac5f4/8bf7cc07176f8ab7/720.mp4
(change 1080 to 240, 360, 480, or 720 if lower quality is desired)
