started exploring more in the Viofo dash-cam settings. For this weekends Test and Tune drag race day, I set the front camera to 4k resolution and the rear camera to 2k resolution. I set the bitrate to highest also.
(fyi: the HD version of the video is still "processing" to youtube, so it might not be the proper quality for a few hours from now)
In this video, you will see:
front footage = 4k
rear footage = 2k
