Here is my review of the Vicovation Marcus 4 car camera. One thing that sets this camera apart from others I've tested is its unusual Cinemascope-esque 21:9 ratio 2560x1080 video mode. It may sound like a gimmick, but it actually makes a lot of sense. Watch the video below to find out more.
As I feared, the youtube re-encoding has introduced a a lot of blocking artifacts into the video samples I show in the review. It's especially noticeable in the first shot where I talk to the camera whilst the car is driving under the trees. If you want to see the original quality of this clip, it's one of the ones I've uploaded in the 'Downloadable Samples' link below. (Filename is '1080p30 Day 3.mov').
