If you play the video below, it will stop playing at 12 seconds in to the video, and you'll see some text appear below the video.
You can use that text as a call to action, like asking the viewer to first sign-up for a free or paid membership, or to your free newsletter, etc before they can watch the full video.
And if you've set it to stop at the Cue Point, even if someone watched the video once and figured out that the video was stopping at a certain point, and tried to refresh the page so that they can try to fast-forward past that point the next time, S3MediaVault won't allow that to happen. So they truly cannot get past the cue point, if you've set it to stop at that point.
But if you've not configured it to stop, then the message below the video will appear at that exact point, and the video will continue playing.
And if you wish to display any kind of message right within the video player itself, S3MediaVault can do that too: Check out the In-Video Ads Feature which can be used on your own videos as well as on YouTube videos.
