OTOH with the unambitious encoding parameters they are very easy to cut with ffmpeg, or at least the MP4s produced by my helmet camera are. I mean, the cheaper the hardware, the fewer frames it'll be able to buffer, so I-frames should come pretty regularly. I wrote a very simple video editor: video playback, some scrubbing controls on the arrow keys to jump around, and space bar to mark / unmark segments to keep (capturing timestamps). Run ffmpeg to cut the bits out then move source video to a different directory, ready to be deleted. This cut down on my video volume 100x, while I still retained a few old commute videos, as a keepsake for that time in my life.
