G'day,
I bought a "Original Ambarella A7 Car DVR 3H2F GS6000 support GPS logger (3H2F)" from Foxoffer () and the video quality is really poor - it looks overly sharpened to the point of looking "gritty" almost. It also looks uber processed or something, with scattered shadows and tree branches and anything else that has a high level of detail turning into a bunch of blocky artifacts and noise.
The nighttime video is so bad as to be unuseable, with objects within the headlights beams being over exposed to the point of being unidentifiable white blobs and everywhere else being blurry like a cheap webcam with a fixed focal point that's been adjusted to a quarter of an inch in front of the lens. I was expecting it to be a bit crap based on the demo videos, but mine seems to be an order of magnitudes worse.
The firmware is "SM3H2FDGC.131028.V1" which I think is the latest based on the naming convention.
Is there any special tricks that might help here, like disabling WDR or changing from ~1440p recording to 1080p? Is there a known issue with some of them and I should be returning it? Should I be using a different firmware?
Video shows it's recording at ~18Mbps, and each 1 minute clip comes in at ~140MB so there's lots of data there. Its just crap data.
Example video (trimmed to remove a private phone conversation in YouTube's editor so it's only 1080p instead of 1440p, but the quality is basically identical):
I've set it to 1080p and will check it again tonight but I can't really see it improving a lot?
EDIT: For comparisons sake, here's my old-ish iTronics ITB-100HD which records at something like 40MB per 1 minute clip (4? 5?Mbps) and has passed through Movie Maker's terrible encoding:
While it lacks the pixel count and clarity of the 3H2F (theoretically), it seems to produce a much cleaner image.
Am I expecting too much from the new cam? Or do I have a legitimate problem here?
