I agree that it's dark, I did mention it was darker than 7Hb in my post, anSorryd it was mentioned by Koganiz as well. BCHobbyist already made note of it earlier. This is why we are all beta testing the FW. Also you do need to realise though, that this is not just a minor tweak to 6Vf, there has been a massive amount of changes done. The picture settings have kind of been overhauled. Don't worry, the brightness will be fixed. This is essentially the first version of all new settings again. If you read my post, I also didn't want to make suggestions for changes to picture quality settings yet as it was a foggy night, and anything I may suggest, might not be correct. I would rather wait for a more clear day and a more clear night.
This also again brings up something I mentioned maybe a month or so ago, that we should make sure we give the same amount of focus on night video as we do on day. Especially since this is the A119S, which is the dashcam marketed specifically for its superior night quality. I would suggest to all the beta testers, that if possible, you provide as many clips of night time driving as you do for day. This is especially important when there has been a new revision of the FW done. It's easy to see what changes have been done for daytime video, but not always so for night.
