Then I found the solution which turned out to be very simple. I stretched the frame out in photoshop. The Key Mission records in a 16:9 format, but Facebook is looking for equirectangular projections which are 2:1.
This weekend I went out on a whim, to shoot the #NoBan #NoWall protest at the White House. Unfortunately, the battery in the KeyMission was very low and I didn't get as much video as I had hoped. I figured I could at least share some of the frames as stills, though.
Last week I had a discussion with Caitlyn Stroh about sharing 360° stills on Facebook after shooting them with the Nikon Key Mission. I did some research and read that Facebook uses EXIF data to determine whether a still photo should be displayed normally or using their panoramic photo "player." That means sharing stills from the KeyMission is easy. The KeyMission already writes the appropriate EXIF data into each .jpg. So the process is super simple, shoot and share, no muss, no fuss no additional work.
Here's a screen shot of a sample photo from Caitlyn, along with the EXIF Data.
What if you didn't shoot stills though?
These are incredibly high res images, and we should think about using them more.
