In this video, I answer all of your questions about using the GoPro HERO5 Black with the Zhiyun Rider-M Wearable Gimbal including raw footage including audio while using the gimbal.
After upgrading from an older GoPro HERO3 to a GoPro HERO5 Black, I thought I'd give the Zhiyun Rider-M Wearable Gimbal a try. I bought the $20 adapter, which now comes with the gimbal if you order it new. I put the setup through its paces, and had some unexpected results.
