When looking at the many different types of cameras for your shoot, it's important to understand how they work. So we'll start with resolution, which will determine how much visual information your camera can capture. Resolution refers to the number of pixels in each dimension that can be displayed. Typically, presented as width by height. When you hear 4K or 8K, it's referring to the approximate width and pixels of an image. Certain cameras and platforms use variations on these categories. The standard resolution for 4K on YouTube, for example, is 3840 by 2160. As you might have guessed, larger resolutions are good for a VR video since this optimizes the image quality for users and in turn, enhances presence. An immersive display capable of outputting a human eye's expected resolution requires about 16K, and we currently don't have that. But today, many professional cameras offer up to 8K video and YouTube can accommodate up to 8192 by 8192 resolution. Remember what we told you about mono and stereo cameras. Stereo cameras provide the depth look, which will either increase file size to achieve desired resolution or lose resolution because of the double image.
