SOLOSHOT3 generates a lot of data while tracking the subject.
We've written algorithms that correlate that data with what's happening in the shot. You will also be able to manually mark a highlight by triple tapping your Tag (available around end of December 2017)
If you don't like a highlight that it pulls, simply say 'no' when reviewing the clips, and it will take that out of your highlight reel.
SOLOSHOTedit is already pretty awesome but will get smarter and smarter as more people use it and interact with their highlights. It adapts to your style!
