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 wide-angle lens and the radio microphone. I believe the wide-angle lens helps reduce the bobbing motion when walking. The radio microphone is much better at reducing wind noise than the built-in camera microphones.
On some recent videos shot on my DJI Pocket 2, I have used a modified Flycam style stabilizer for improved Z-axis smoothing. I have removed the weight plate at the bottom of the stabilizer and taped one of the lighter weights near the end of the bar. The camera floats at about 45 degrees to the horizontal. I also try to walk Ninja style while filming.
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.
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.
