what software are you using? I suppose GoPro has its own. I just mounted a Fly 6 and 12 on my bike. Sadly the impetuous to do so is two rear end collisions and one front end, resulting in one death and two injuries for friends of mine. The Cycliq Fly cameras aren't as good as the GoPros but offer longer run times and lights.
I took a still this morning of the sun rising over the south central Texas Prairie.

I sometimes just use USB-C to transfer the movies to MBP. I then use iMovie to import the clips into my MBP and to do the post production stuff on them from there. Sometimes I use the GoPro app to transfer the clips to my iPhone and then use the iOS version of iMovie to get the clips ready. With the GoPro app it can transfer media wirelessly via wi-fi.

In either case I normally use the built in publish to YouTube functionality to publish up to YouTube.

Your picture is very nice! The way out I was riding west so I was facing away from the sun at the ass crack of dawn this morning. Couldn't get out early enough to be on the return part and facing east.

I'm just doing my time lapses just for entertainment.

I don't have time to play with it now, but it is suppose to allow putting Garmin stats from an Edge computer on the video plus other features.
