VIOFO WM1 – Daytime Video – CPL vs No CPL – Dropped Audio Frames

I created a short comparison video using two WM1 dash cameras (one is a production unit and one is a pre-production unit). The production unit has a CPL filter installed and the pre-production unit has no CPL filter installed. I point out a loss of three 3 audio frames at the end of each 1-minute video file created by the WM1 with firmware v1.0_0421.
