Thanks for the work and much appreciated. That said, I'm struggling to see any advantage gained atm.
Yes agreed but to my eyes I'd rather have the default. The top picture is disappointing in both sharpness and detail eg the blurry grass at the side of the road. As I presume you were stationary during both pictures, there's no cause other than the changes (admittedly the lower light levels made the modd'ed picture less appealing as well, although that can't be helped).
The main gains in bit rate are going to be seen with movement and highly complex scenery eg a narrower tree / bush lined road with grass each side so there's lot of small detail. I'm not sure a stationary picture is really going to show it off to the best ability.
So it's using VBR instead of CBR. Definitely a good move by Viofo provided the limiters are set so as not too allow it to go too low. A recent recording of mine shows 23812kbs under video analysis and 23909kbs with audio. That's a definite improvement over the WR1 which I believe showed 12mbs.
interesting comparison, thanks for the effort, the Sharpness difference is noticeable, the MOD code difference was 50% less, will release 40% and 60%.
verify 1080P @30fps works normally, it may crash.

The bitrate is limited in the firmware of the manufacturer, it is variable, for example, in the MOD at 28 MB / s can grow up to 51 Mbps on complex scenes.
