hot spots / hyperlinks in video frame to provide multilevel interactivity
We are looking for a way to provide some interactivity via hot spots in the video – either via graphic overlay of button images, or "invisibly" by having an interactive region defined that corresponds with an image in the video during a specified time range. An example: an object or signage showing in a scene which when clicked upon will trigger something else – a web page launch, or maybe an alternate story outcome. Whether the object in the video is a product, a person, an object, or an animal – We might do some post-production things to draw the user's attention to the clickable image. So, is it possible to overlay hot spot regions or hot spot graphics? Would it be HTML5 compliant?
