Dude, I feel your pain! I used to record my entire ride, from driveway to destination. It was so painful - it would take me anywhere from 20 minutes to 3 or 4 hours just to cull the footage down to what I thought I would use.
Now, I use GoPro's The Remote to start/stop recording, and while it takes a bit longer to sync [especially if there's no slow ride or stop in the footage], it's much faster to edit a video together. You can also leave yourself notes while you record, things like, "Put this in at the beginning" or "About to start talking, cut before this" - and when you are playing through the footage, you'll have those references to help you edit.
It took me a good 200-300 videos before I got the muscle memory for editing down and the recording style to where it plays nicely with my editing style. Now, the videos are much faster to edit and take up less space on my hard drives.
Also, I don't cheerlead anyone, so any praise I give is earned. Just ask my kids
