after my first trip with the K2 installed, I am a little bit disappointed about the video quality because of compression artifacts.
When the area beside the road is clear (e.g. open fields), everything looks nice and clear in the video. But as soon as there are more objects (e.g. much trees with leafless branches) the video gets blurry in some areas. Below are some examples.
For me it seems, that the bitrate isn't high enough to compress/save all the details.
The vidos of my K2 are recorded with a bitrate of max 12000 kbps, while the videos of a friend of mine are recorded at up to 24000 kbps (using a Sony ActionCam).
My SD-Card is a SanDisk 32GB HC I (UHS Class 1)
Firmware of K2: K2.20180925.V0.39
Its hard to see at that resolution here in the forum. You need to see it at full screen. Watch the lower right side of the road and the number plate of the incoming car.
Recorded at 60 km/h.
In comparison this picture without artifacts, recorded only some seconds later. Same road, same speed. Everything looks fine. You can see every detail of the road.
Another example. Again hard to see at that resolution. You need so see it at full screen.
The roadside at the lower left and right corner looks blurry. Recorded at 30 km/h.
And in comparison the same road without artifacts, some seconds later
Everything looks fine and the roadside is very detailed. You can nearly count the grasses.
Any suggestions what I can do against those artifacts?
I tried to check whether the K2 does a better job in 720p or not, but I cannot change the resolution (see other topic)
