The Video Preview window in 360° mode
A 360° video is a normal 2-dimensional video where the content of the 360° sphere is mapped on a rectangular surface.
Click the 360° Preview Button to switch the Preview window into 360° mode, where you can interactively adjust the perspective directly in the Preview window using the mouse.
Drag with the mouse in the Preview window to change the direction. Use the moose wheel to zoom in and out the video.
NOTE The 360° mode for the Preview Window is not automatically activated when switching a project to 360° because sometimes it is necessary to see the video in its original rectificated form for fine-tunig the stitching.
