By default, S3MediaVault does not track the video watch time of anonymous users (aka, those who have not logged in to WordPress).
This option enables that tracking, which works as follows:
* If you use a S3MediaVault shortcode for a video on your home page, chances are that a visitor to your website is not going to be logged in.
* So they start watching the video which is, say, 5 minutes long.
* If they come back to your website on a different day, the same video would normally start from the beginning.
* But if you Enable Anonymous User Watch Time Tracking, S3MediaVault will remember how long this anonymous viewer watched that video previously (as long as it's the the same computer and browser).
* And they can pick up where they previously left off.
* You can also use this feature to have a video on your home page, pause it using S3MediaVault's "Cue Point" at a certain point, show them a sign up form below the video, and after they submit, take them to another page which has the exact same shortcode. And now, it will play from where they previously stopped watching.
* So you can use it for a "Sign Up To Continue" tactic to get leads.
