Even though many 360 cameras are equipped with gyros and other sensors to help stabilize video output, it's usually not enough to deal with all types of unwanted motion. Facebook will automatically stabilize 360 videos uploaded to their site, and for certain types of content, it works well. I've tested this recently to understand the limits of Facebook's software, and you can observe the results below. The first video was taken during a recent protest march in Ottawa. I mounted the camera on a telescopic monopod, and held it above my head.
It works rather well, although there is an odd floating effect that I don't see in the original. I've looked at other videos when the operator is walking with the camera on a monopod something similar, and for the most part, the algorithm does a good job of damping out unwanted motion. However, it's not adept at stabilizing everything. In the next video, take note of the odd stretching distortion as Facebook attempts to compensate for the swaying motion of the monopod as I skate along the frozen Rideau Canal.
The obvious solution would be to mount the camera on a gimbal. There are many options for conventional cameras that cater for all types of users, from amateurs all the way up to professional videographers. You can buy gimbals that can be held, mounted on your body or on a bike, car, drone or just about anything. But for 360 cameras the options are few at the moment. A standard 3-Axis gimbal won't work with my Samsung Gear 360, the Nikon Keymission, or any other 360 camera because they work on the principle that there is one lens and it faces in one direction. The second lens would be blocked by the gimbal. There are some gimbals available for 360 video cameras, but most are very expensive. That said, some inventive types have come up with clever low-cost solutions. One in particular suits me because it will work with the Samsung. It consists of a 3D-printed accessory (see red component in the photos below) and a counterweight. According to it's French creator, Denis Fritsch, the adapter will only fit the the Zhiyun Smooth II. I was lucky enough to find a used Smooth II for about half of the retail price on eBay. I've also ordered the adapter from Denis, and I expect to see both arrive next week for testing. I'll post the results here as soon as I can. There will be gimbals hitting the market later this year that are intended specifically for 360 cameras, but until then, I hope this will do the job.
