Seems that Viofo will become a standard regarding Ultra Wide dashcams. Implementing new features requested by the users on existing models is making Viofo a trusted brand.
UltraWide 1080, WFHD, 2560 x 1080, Wikipedia.
I don't know how many Novatek dashcams are offering 21:9 aspect ratio and I consider Viofo can make a good decision to implement it on 2K dashcams because the final result is 2560x1080, so it is not under 1080p resolution to make some people worrying that 21:9 aspect ratio is not even Full HD.
I am big fan of 21:9 aspect ratio. Also I am fan of 30FPS instead of 60FPS and the 21:9 mode is only 30FPS in this firmware for testing.
Until now Viofo was offering the Ultra Wide 21:9 aspect ratio only for Viofo A129 Pro as: 3840x1600p 30FPS = 4K 21:9 (43mbps: 1min = 300MB)
In a testing firmware for Viofo A119 V3, Viofo introduced a new resolution as: 2560x1080p 30FPS = 2K 21:9 (32mbps: 1min = 220MB)
The Ultra Wide parameters for Viofo A129 Plus are: 2560x1080p 30FPS = 2K 21:9 (32mbps: 1min = 220MB)
Viofo A119 V3 vs Viofo A129 Plus 21:9 aspect ratio comparison:
Here you can see the differences between 21:9 and 16:9 modes on the same Viofo dashcam:
The advantages of 21:9 aspect ratio (which I am using always!) are:
1. same bitrate as for 16:9 is used also for 21:9 which means more Bits/(Pixel*Frame) and the result should be better image for 21.9 compared to 16:9
2. sky and dashboard and engine hood are not important and in 21:9 mode are less, no bitrate wasted to encode unnecessary parts of the image
3. nice Cinema Mode looking of the videos, nice option for vloggers or when you want to record a trip
4. for 2 channels models will be more nice to combine as stack vertical 2 videos recorded as 21:9, see another example.
5. no 60FPS mode. Please do not start forum fight against me, it is my opinion and nobody will change it with any dashcam released until 2021!
The only disadvantage can be for some people which can be afraid that the traffic lights will not appear if they are stopped into the first position. But you can put Pause on this video at 00:36 and see that common traffic lights are recorded into the video without any problems. Of course, for some „people” the black bars of a 21:9 video which appear at the top and the bottom of their 16:9 TV can be annoying.
