How does Slideator create the slide thumbs and integrate them with the video

Using the new Slideator Advanced Format (ASF) invented by Slideator, the video, slide thumbs, transition time and other information are combined together in one ASF file. This ASF file is created by the Recorder when you you finish recording. When you upload this ASF file, Slideator platform extracts video, slides, transition time and other information and creates the video player and right-hand slide thumbnail menu. Using the slide thumbnail, the user can control the video player and skip forward or back through the video presentation.
