One kibibyte (KiB for short) is an equivalent of 1024 bytes, and one mebibyte (MiB) is the same as 1024² bytes. These are not popular, which means you might not have heard about prefixes such as kibi- or mebi. On the other hand, binary unit prefixes have a numerical value expressed as a power of two. You undoubtedly know them: milli-, centi-, kilo-, mega-, and giga- are all metric prefixes. Metric prefixes always have a numerical value of 10ⁿ (so 10, 100, 1000, and so on). The whole confusion stems from mixing up two types of unit prefixes: metric and binary. Each prefix has a fixed numerical value: for instance, kilo- refers to a thousand (so one kilogram is equal to a thousand grams), and mega- refers to a million (so one megapixel consists of a million pixels. It is the word that stands just before the unit name – for example, kilo- or mega. Which one is true?īefore answering this question, let's clarify what a unit prefix is. In the first version, one kilobyte is the equivalent of 1000 bytes, and in the second – of 1024 bytes. You've undoubtedly heard two contradictory stories. If you're not an expert on data size, you are probably perplexed by the conversion between different units. Visit our byte conversion calculator to learn mo The file size is expressed in data size units, such as bytes, kilobytes, or megabytes. N is obtained by multiplying these two values, so finally, you can arrive at the following formula for video file size:įile size = duration × frame rate × frame size It usually ranges from 12 fps for animation through 24 fps for regular movies to even 60 fps. The frame rate is the number of frames per second ( fps) of the video. To calculate the value of N, you need two pieces of information: the duration of the video and its frame rate. Where N is the number of frames in a video. It means that we can find the total file size using: If you want to calculate the video file size, you need to sum up the data size of each of these digital still images. Each frame is shown on the screen for a very short time (for example, 1/24 of a second), which makes the images appear to blend together. These still images are called video frames.
