So I might have spoken too soon. I pulled my card and some (maybe a quarter) of my videos have corruption... I kind of just "set and forget" the Biker Pro so I never investigated further after seeing that it worked a few times.
I think it is definitely power related though. I have one video file where when I turned the key it started recording, and then the moment I hit the starter, the audio kept recording but the video froze. I'm sure the power surge wasn't a coincidence.
What I'm thinking might be a decent solution is getting the smallest power bank you can find and hooking the camera up to that, then the bike to the power bank, to help provide steady power. It'll keep recording after you stop, but I think that seems like a decent tradeoff.
