To provide you with a seamless video, those images have to be “stitched” together. Most 360° cameras have two lenses and some have four. For super-smooth imaging, look for frame rates of 50 fps and more. Some cameras offer lower rates to reduce file sizes, and this can be a useful option in situations where you’re simply recording factual information. The minimum for flicker-free playback is about 30 frames per second (fps). High resolution for these devices equates to 8K or 12K, which provides fabulous images if you can afford it. This is a noticeable improvement over 4K, but you need to spend more to get it. There are several more steps in quality, starting at around 5.5K. Entry-level 360° cameras might only be 2K, which are perhaps best looked at as cheap fun. It’s still good, but it isn’t as crisp by comparison. In terms of resolution, 4K is pretty impressive in standard video, but when you’ve got a “whole world” view, those pixels have to go a lot farther. Some features may only be available for particular operating systems, so check device compatibility carefully.
