There's an alternative or supplement to VIRB Edit for reframing and editing 360 video.
VIRB Edit works well for adding GPS data and reframing, but is super limited as editing software.
On the other hand, Premiere Pro is a great editor, but isn't great for reframing.
But there's a free plugin for PP that allows you to reframe like VIRB Edit's HyperFrame Director. It's called GoPro FX Reframe (available for download from GoPro).
I'm just experimenting with it. But here's the general workflow:
Import into VIRB Edit.
Add G-Mextrix data as desired.
Export full clip as 360 .mp4.
Add the GoPro FX plugin to Premiere Pro
Import your 360 clip into Premiere Pro
Create a proxy if the clip is too big for your computer.
Add clip to the timeline (Adjust 360 settings as needed)
Drop the GoPro FX Effect onto your clip.
Then in the Effects pane, use the pan, tilt, rotate, and zoom controls along with key frames to manipulate your video.
Edit, and titles, other effects, sound, etc. Then export you finished project.
Works well so far.
Note: Requires Premiere Pro 2018 or newer.
Like always, there are plenty of tutorials on YouTube.
