Camera quality and viewing offline on a computer

[hgpilot]

Over the last 2 weeks I've gotten the middle finger from 3 different people in my neighborhood (and not because of my driving) and I went down a rabbit trail looking at my footage to figure it out (not gonna public shame them - just interested). When I pull the USB drive from the glovebox and use my PC to view the files, the video quality is marginal at best. Video captured while parking is pretty good but while CT is moving, all video is low resolution, jerky, pixelated, almost no significant detail (license plate, images of people in vehicles). I've tried different video packages (PC) to take screenshots, clean up video / stills - but when you don't have much to work with, the potential isn't great. I know these are only 1.2 megapixel cameras - but any hints on cleaning up video (after-market software? AI video cleanup?) of moving vehicles?
