For my walking around type videos, I am currently using a DJI Pocket 2 camera. For my skiing videos, I have used GoPro cameras. My editing software of choice is PowerDirector.
Walking Around Videos
The things I use most from the Creator Combo are the wi-fi adapter and the radio microphone. The radio microphone has a cover to reduce wind noise, it can also start recording remotely.
In some recent videos shot on my DJI Pocket 2, I have used a modified Neewer stabilizer for improved Z-axis smoothing. I removed the weight plate at the bottom of the stabilizer and taped one of the weights near the end of the bar to balance the camera.
Ski videos
I have found the GoPro MAX 350 is good for reducing the side-to-side movement one does whilst skiing. I have mounted it on a ski pole to utilize the 360 capability and also on a chest mount with reframing.
On my ski videos, I sometimes mount my GoPro camera on a Stuntman chest harness. This has a solid base plate that holds the camera firmly. I am confident that if I fell on my chest the camera would not penetrate the plate.
Editing
When filming is done I use Cyberlink Power Director Ultra software to join the clips together for presentation. I have version 15 which does everything I want. They seem to bring out new versions at regular intervals so are on to higher numbers now. There are a lot of good Power Director tutorials on the Internet so it is easy to learn how to use it. For basic editing, it is a matter of importing the clips I want to use and then dragging them onto the timeline in the order I want. I can then create my video with a selection of pre-set resolutions and formats. There is also an expert mode where I can create almost any editing effect I have seen other editing software do.
