  • A video wider than square can never be a Short. sprkly warns you before you post.
  • sprkly posts video as 9:16 or 3:4. Both are tall, so both fit a Short.
  • Shorts take no thumbnail upload. sprkly puts your cover in as the first frame.
  • YouTube takes no photos. sprkly tells you before you post.
