Its always nice when a video remembers where you left off, and does not force you to the beginning, or to randomly seek for the location you stopped. I recently watched a YouTube video that resumed from my stopping point 3 years earlier (ok, so that was not super helpful!).

Would you like to use session data to resume videos for your users? You can use the resuke a video application to track each user's progress with the video, and then start the video at the last point their viewing was tracked.
