For the past few weeks I have been driving with a modified GitUp F1 alongside a Mobius Maxi, to look at some similarities and differences between them.
I have previously compared the standard GitUp F1 vs the Mobius Maxi, where the relatively slow F2.8 lens on the F1 created much higher motion blur than in the Maxi.
Do these high-resolution action cameras offer any benefits over a good-quality 2MP dashcam? And what are the drawbacks?
GitUp F1 (3840x2610@30fps)
I have replaced the original 170deg wide-angle F2.8 lens with the F1.6 lens from an A129, which gives a field of view around 140deg on the F1. I did this to experiment with a faster lens more suitable for dashcam use. I understand that @gitup are developing their own fast lens for the F1.
I am also using MOD#1.5+Sharp modified firmware developed by @Falsificator which enhances the image quality and increases the bitrate to 100Mbps to produce detailed and fluent video even in complex scenes.
Mobius Maxi (2704x1524@30fps)
This camera is not modified in any way. It has an F1.5 lens with approx. 130deg field of view. It is running the latest FW V2.11 and is recording at 60.1Mbps.
Viofo A129 (1920x1080@30fps)
This camera has an F1.6 lens with approx. 130deg field of view. It has an IMX291 sensor which is more light-sensitive than the sensors used in the F1 and Maxi, and is widely regarded as one of the best 2MP dashcam sensors currently available.
I am using MOD-4Uj modified firmware developed by @BCHobbyist which improves IQ by enhancing sharpness and edge-detection, and increasing the bitrate to 24.6Mbps.
Video Notes
I have compiled F1 and Maxi comparison videos at 1080p so you can compare brightness, dynamic range and colour. Unfortunately, YouTube cannot convey the level of detail present in the original videos, so I have included unedited source frames from the original video files, plus comparative frames from the A129 for reference.
High resolution video issues
It has been discussed in these forums that high-bitrate high-resolution video files may present some difficulties when forwarding them to insurance companies, solicitors, the police and other legal professionals who may be viewing your dashcam video on relatively old PC hardware. In recognition of this, I plan to re-test these cameras at a later date with all of them set to 1080p60 video format.
