You can now download GoPro VR Plugins for Adobe Premiere and After Effects for free, with effects including GoPro VR Reframe! These plugins can be used to frame a 360 video as a cropped non-360 video, or straighten the horizon of your 360 video.
GoPro has created several plugins for 360 videos for Adobe Premiere and After Effects, including GoPro VR Plugin, which includes GoPro VR Reframe, which as of November 2018 is the only effect for Premiere to convert a 360 video as a flat, non-360 overcapture video.
These plugins were previously available only if you had Kolor Autopano Video, a $749 stitching software. However, you can now download them for free. Here is the current download link for Adobe Premiere CC 2019 and After Effects CC 2019.
You’ll be glad to know the GoPro VR plugin works with any 360 video, from any camera. In the sample above, I’m using it with a video from Garmin Virb 360.
There’s another software called Insta360 Studio (tutorial here) that can also convert a 360 video into a flat, overcapture-style video. However, Insta360 Studio is limited to 4K videos. In addition, Insta360 Studio cannot create a reframed video from a 360 photo. By contrast, Premiere and VR Reframe are not limited to 4K. Moreover, VR Reframe can be applied to photos.
