Nice vids.
Multiple camera angles really allows you to make more interesting - or at least more varied - videos. I run 3 VIRBs and a Sena 10C.
A friend of mine teaches web design, writes music, and does some video production. After watching my Sotres trail video he commented that it needed more edits - shorter clips. Kids today need constant barrage on the senses - I think that's where he's coming from. He was watching my video as a non-biker. I pointed out that I'd put my videos together with a biker viewership in mind, not a general public viewership.
He commented on music too. I have F&F edits of my Sotres videos, with my own preferred music - Led Zeppelin, KT Tunstall, Gordon Giltrap, John Mayer, America, Bell X1, Credence... But my YT edits use copyright-free music. Matey says YT will only take down videos that feature regular music if the video is monetised.
I use DaVinci Resolve 15 - completely free, and very good. Mostly intuitive, lots of how-to stuff on YT.
I find it hard to whittle out the non-best bits - some trips just feature only great roads & scenery.
Image stability is a big thing. Some mounts on my mate's bike resulted in very wobbly footage - barely usable, and largely a waste of memory and battery. So we're still experimenting with mounts. VIRBs do have a stabilised mode - must have a play with that.
