The UHD video test covers several features of the Samsung Galaxy S5 video camera.
mp4 encoding quality
Manual ISO exposure
CMOS rolling suhtter
Autofucus and auto exposure
The manual auto ISO text was taken in low light. It was raining and was about 5.30pm. The second last clip at 100 ISO actually shows the actual clow light condition I noted that day.
Rolling shutter was not noticeable during faster pans and moire was very well controlled. You will notice only a little moire in the sky shot with the fence. Encoding to mp4 is very high quality as the details on the rough wall and the swimming pool water movement is not blocky.
