Wonderful weather. It’s like that here too, though I’m not sure what your temps are and how they compare without going to Google. Lol.
I don’t expect I’d find boats relaxing at all. Lots of people have ‘em here on Arran, as you would expect. I’ll stick to my guitars!
How are you doing the black bars thing on your b roll? Is that you switching from phone to camera? 4:3 to 16:9?
The black bars are just a crop overlay on the video. So I add an adjustment layer over the video, add the effect "Crop" onto it and then bring them in to about 11% or so.
