Multiple-lens and synchronized cameras 3D HERO and Dual HERO GoPro released the 3D HERO system in April 2011, which coupled two HD HERO cameras via a synchronization cable in a single housing to form a stereoscopic 3D camera. One of the cameras is used in upside-down mode. The 3D HERO system is also compatible with the HD HERO2. The synchronized videos are processed using GoPro CineForm software and exported as an anaglyph to be viewed wearing red-cyan glasses. In 2014, GoPro released an update as the Dual HERO system, which provides similar functionality using two HERO3+ Black edition cameras. The updated Dual HERO BacPac sync/link cable now has an asymmetric design: the right or primary camera (viewed with the lens facing away from the user) is larger than the left (secondary) camera, and the left camera is used in upside-down mode. Like the preceding 3D HERO, the Dual HERO uses CineForm software to process synchronized images and videos for export as anaglyphs. Odyssey The Odyssey is a 16-camera panoramic stereo rig designed to produce content for the Google Jump virtual reality platform by synchronizing the cameras and automatically stitching their footage together. The Odyssey was originally announced at Google I/O in May 2015 and GoPro began taking applications from "professional content creators" in September for the US$15,000 rig, which included 16 GoPro HERO4 Black cameras; limited shipments began in May 2016. Omni The Omni also was announced in May 2015, leveraging its recent acquisition of Kolor, which developed software to stitch video footage together; Omni was a camera rig that synchronizes six GoPro HERO4 Black cameras, allowing users to stitch and make virtual reality 360° videos. Omni began shipping in August 2016. Fusion The Fusion was announced alongside the HERO6 Black and released on November
