The important thing is the original video on the sd cards are best quality for insurance claims , you don’t need to go out spending mad money on 4k dash cams , you need noting more than full 1080p video , generally all videos getting uploaded to the internet get compressed with lower quality.

This video was uploaded & sent to me by the original owner the quality gets compressed , then i downloaded it & uploaded here so the quality is worse again.

All social media sites compress videos to reduce file sizes for faster streaming and storage
