Using Virb Edit 5.2.1 on a Mac in hyperframe mode, I often get bad frames when exporting. You can see them as "jumps" in this video:

Here is a video which breaks down the different types of issues I am seeing:

I am surprised I was not able to find other people complaining about this. Maybe it doesn't happen on the Windows version?
My camera is running 3.50, and I am using in camera stitching. The source file coming out of the camera does not show the issue, but I see it when exporting 360 video or Hyperframe videos.
