I am currently using a DJI Pocket 3 camera for my walking around type videos. I use a GoPro MAX 360 camera for my skiing videos. My editing software of choice is Cyberlink PowerDirector.
Walking Around Videos
The DJI Pocket 3 accessories left to right: battery handle, mini tripod, camera with wrist strap in a DJI case, DJI radio microphone with windscreen, the mic can also start the camera recording remotely, and a small Ubayee shoulder bag to hold these items (dimensions: 21 × 13 × 5 cm). The shoulder bag also has room for a mobile phone and a few other items.
Flycam-style stabilizer
This Z axis stabilizer smooths out some of the up and down movement when walking. It is converted from a Neewer handheld stabilizer (pictured on the right). The original camera mount was removed and replaced with a GoPro camera mount. This is held in place with a self-adhesive foam pad plus Gaffer tape for extra security. An arrangement of GoPro extension arms holds the camera. It is important to get the weight of the camera below the main pole so it hangs in the correct orientation. The pole that extends to the other side of the hand grip should balance the camera to keep the arrangement more or less horizontal. The weighted section has been removed, as the pole on its own is enough 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. The helmet mount is attached by a self-adhesive foam pad supplied with the camera.
The GoPro MAX 360 accessories left to right: hex wrench, helmet mount, remote control with charging cable, spare batteries with charger, soft camera bag with thumb screw wrench attached, Ulanzi hard case.
Editing
When filming is done, I use Cyberlink Power Director Ultra software to join the clips together for presentation. I have version 20 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 often add music downloaded from the YouTube audio library. I can then create my video with a selection of pre-set resolutions and formats. Furthermore, I use the expert mode, where I can create almost any editing effect I have seen other editing software do.
