You can not tell the difference easy. If you record the same video with say 5,10,15,20Mbps and run them side by side you will see that
there is a difference but, the higher bit rate mostly helps against getting grainy or blocky video. For 1080p 30fps 15-23Mbps should
be more than enough, if you go to 60fps you would need 23-30Mbps or something like that to capture the extra frames.
It is when you get below 10Mbps you will start to see the video deteriorate.
Remember, dashcams should have a bit higher bit rate than a video recorded in a stationary postilion or when standing still
and filming with a smart phone. And that is because the scenery if constantly moving, so over all you need a
higher sustained bit rate to keep the video smooth. But that is nothing new, everyone knows that.
A much bigger issue with dashcams is getting stable video and not the bitrate it self,
or a sharp clear image. Easy to tell from all the videos out there.
