Quality of picture underwhelming
First run with the system today and the picture quality both in 2k and 1080 EIS is not that good.
As example cannot make out oncoming car registrations as vehicles pass and even road signs are barely discernible.
Selected high bit rate in both cases.
Go on what am I missing here?

Hi, can you post a sample?

the 2k, the roadsigns just readable

Hi Karel,
Does the SD card meet Innovv’s requirements? A write speed higher than U1.
Also try lowering the bitrate a bit. -

I checked the 2k video and for me the reason is quite obvious. The bit rate of the K7 is too low to record all details. For this reason, some areas become blurred. This is also known as compression artifacts.
Just check the first second of the video. I’ve zoomed in a little bit to make the effect more visible.
At first the grasses at the right side and the tree on the left are clearly and sharply depicted.
Then, only some frames later, when the tree on the right side with all the branches and needles gets closer, the compression algorithm becomes overloaded and has to omit details. As a result, the grasses on the right and the tree on the left gets blurred. Even the sign is hardly to read.
So my conclusion is: This is not a problem with the SD card or its write speed, but with the bitrate. The bitrate of the K7 is simply too low to record all the details.
If someone can remember. The K2 had the same problem till I modified the firmware to raise the bitrate. Unfortunately this is not possible at the K7 due to hardware limitations.
