Charles Yeager (yeagerfilm.com) shows us how to stitch 360° footage in After Effects using the SkyBox Studio 360/VR plugin. This method gives better control than the automatic stitching app that comes with the camera. The 360° footage is shot with 2 Fisheye lenses at 3840 x 1920, 30 fps, and there is only one stitch line to deal with. This technique works with any 360 camera footage that uses 2 lenses, such as the Ricoh Theta, Kodak Pixpro, Nikon KeyMission 360, and LG 360. The project file is courtesy Mikey Borup (After Effects with Mikey).
