i just purchased a t5ethe other day and all the footage I've recorded is really grainy even on a proper 4k display.i have the latest firmware directly from thieye website. i have video quality set to super fine, sharpness set to strong, AWB set to auto, EV 0.0. i have tried messing with these settings and nothing seems to remove the grainy footage. at a stoplight directly behind another car, with good lighting in daylight, i can just barely make out a license plate, any further and its just blurry nonsense. I'm not sure if any of my settings need to be adjusted differently, but from the sample footage I've seen of these cameras i feel like i must be doing something wrong. any help would be greatly appreciated.
