  7.  * This is V1.5 of the YouTube thumbnail and data downloader. It will get thumbs and video ID, title, viewCount, uploadDate and store
  8.  * them to jpgs and an index file called 1A_YouTube.txt. It's meant to be used along with a downloader like mediahuman or youtube-dl
  9.  * to get the extra information that may be needed for a future offline video archival system.
