On my last Driving with John Chow video, I showed you the video blogging setup I used to film each episode.
For this driving video, I give you a comparison of the audio quality between the Zoom H1 with GiantSquid lav mic, against the built in audio found in the GoPro Hero 4 Black Edition. Great video starts with great audio, and the Zoom H1 with GiantSquid will give you great audio.
