I had an Action Cam a few years a go and it was a total PITA. I rarely used it due to all the faffing, getting it mounted right, external recorder, etc. I was put off on-board cameras for ages after that .
Got a Go-Pro now and haven’t looked back. Easy to mount, no hassle, got a wee tripod for Camelbak to give a bit of variety. then I either:
1) Use iPad SD card reader (rip off incidentally), to do a very basic edit and stick in Vimeo, etc. Takes 10 mins over a brew.
2) File for posterity as others have said. Takes 5 mins.
3) Do a bit of an edit (I’m no Spielberg as below shows, but does the job).
