Video Resolutions

Resolution is a measurement of the number of pixels in a video file that forms dimensions. This measurement usually appears in a format like "1920 X 1080", which in this case, refers to a shot that's 1920 pixels wide and 1080 pixels high. Aspect ratio is closely related to resolution, as it derives its value by the ratio of horizontal pixels to vertical pixels. For instance, a frame with a resolution of "1920 X 1080" would have an aspect ratio of 16:9, which translates to the common widescreen on most televisions and computers. However, aspect ratios can get more complex with resolutions larger than HD, and in those cases they're expressed by a ratio of one pixel of height to the number of pixels of width, like 1:1.9. Both these concepts are important in video production because depending on how you want to display your videos, it's important to know what resolution to shoot at, and what camera offers you the best aspect ratio to get your work done.
