One thing people forget easily is the exposure time.
IMX291 (used on the A119S) has bigger pixels, which means it needs less light to get the same level of brightness.
As a result, the exposure time is shorter, which means less blurry videos.
When looking at small objects like license plates, it is extremely important.
This is the reason why I'm really waiting for the A119S because I believe it will offer better license plate visibility.
Another thing is the dynamic range.
The dynamic range is the different levels of light the sensor can render on the final picture, without overexposing or underexposing.
Unfortunately Sony doesn't specify the dynamic range of their sensors, unlike other competitors, so it's not easy to compare, but generally newer sensors feature a better dynamic range.
This is also very important for night videos, where sometimes you see everything except the license plates which are overexposed due to the low-beams lighting them.
I am waiting for more sample videos to assess if the IMX291 used in the A119S really has a good dynamic range or not, but I'm optimistic so far.
PS: So when evaluating night-time videos, generally the "look" of the video is not important. Because in case of an accident, what's going to be useful is not that the video "looks good" (like color balance), but what data can actually be extracted from the video. It is very important to keep this in mind when evaluating dashcams, it's not a television camera, but more a technical product meant to collect information in case of an accident (and also for fun, cheers to Redditers from /r/Roadcam ;D)
