You can easily create presentation videos from your spherical panoramas uploaded to the TrueVirtualTours website. See some examples of how they can look and how to create them.
The order is as follows: 1) upload to the site spherical panoramas from which you plan to create a virtual tour; 2) from the list of uploaded panoramas add each panorama to the virtual tour (Add to 3D tour link); 3) open the created virtual tour, edit the panorama order, select the main panorama, set transition points (tunnels).
