The first revolution of interactive video is the nature of video itself. Linear video only allows the visualisation of a version previously established by the author and within the limits of the camera range of vision reflected on the rectangular viewfinder.
With interactive video, users have the possibility to choose which take, angle or point of view they want at each time and in which part of the space of the scene they would like to focus on. These choices are possible due to the new types of video arisen from the possibilities of interactivity:
Standard video: classic movie clips.
Multivideo: composite video, multi-camera, multi-view or multi-angle.
A video composed of different videos being reproduced all at once, always synchronised.
Spherical 360 video: video captured by a camera with multiple objectives covering any visual angle and, if conveniently processed, results in a video that can be explored manually, at the option of the user.
Empty video: a particular type of video, acting as a multi-purpose resource.
