Immersive media content navigation and editing techniques

In a digital medium environment to navigate spherical video, a computing device comprising:

• a processing system;
• a display device;
• and
• a computer-readable storage medium having instructions stored thereon that, responsive to execution by the processing system, causes the processing system to perform operations comprising:
• generating a two-dimensional (2D) equirectangular projection of a spherical video;
• displaying, on the display device, the 2D equirectangular projection of the spherical video and a visual position indicator in a navigator portion of a user interface of a content editing application, the visual position indicator indicating a position within the spherical video;
• generating a planar spherical view of a portion of the spherical video;
• displaying, on the display device, the planar spherical view of the portion of the spherical video in a compositor portion of the user interface, the portion of the spherical video determined based on the position;
• receiving, via the navigator portion or the compositor portion of the user interface, user input to navigate to a different position within the spherical video;
• and
• displaying corresponding visual changes in both the navigator portion and the compositor portion of the user interface.

In a digital medium environment, a method implemented by a computing device, the method comprising:

• generating, by the computing device, a two-dimensional (2D) equirectangular projection of a spherical video;
• displaying, by the computing device, the 2D equirectangular projection of the spherical video and a visual position indicator in a navigator portion of a user interface of a content editing application, the visual position indicator indicating a position within the spherical video;
• generating, by the computing device, a planar spherical view of a portion of the spherical video, the portion of the spherical video determined based at least in part on the position;
• displaying, by the computing device, the planar spherical view of the portion of the spherical video in a compositor portion of the user interface;
• receiving, by the computing device, user input to add at least one of spherical audio, a visual object, or mono audio to the spherical video;
• and
• enabling, via the navigation portion or the compositor portion of the user interface, direct manipulation of the spherical video, the spherical audio, the visual object, or the mono audio.
