I've a Mio Mivue 618 dash cam. However, this question applies to any type of dash cam.
On the Mivue 618 dash cam, both the 1080p and 1296p resolution use the same bitrate of 15 mbps.
Looking at the recorded video files, the 1080p has a much more clear picture with more details, although the resolution is lower than the 1296p.
Question: Is this because the 1296p has less color depth?
After all, they both use a bitrate of 15 mbps. But as 1296p has more pixels than 1080p, the bits per pixel have to be less for 1296p. They use the same bitrate (and therefore same file size), so, something has to go, right? As the bits per pixel stand for the color depth, it would explain why 1080p is more clear and ''sharper''. Sharper as in, 'you can distinguish details much better'. Because with more colors per pixel, there's more to show. And I suspect that (because of the same bitrate), the 1026p video has a much lower color depth than the 1080p video.
Is this a right conclusion??
Cheers.
