my settings i just use the highest resolution video. btw turn off wifi function (i find that this greatly reduces the heat, otherwise it gets hot until can fry egg on it). Only turn on wifi function if needed, e.g. update software or sync with phone app.

if you dont mind, upload to youtube or some other video hosting site the original video then only i can judge whether your dashcam video is normal or got anything wrong.

btw, you view the video on PC after taking out microSD card or directly from dashcam/phone?
