Now we have MB/s (megabytes per second), but we need that in terms of minutes, not seconds. That tells me that I need to divide by 8, not multiply by 8: We are starting with bits in this case, so we should end up with fewer bytes.

We have more feet than yards, just as we have more bits than bytes.

But do we divide by 8 or multiply by 8? I think of it like the word “yard,” which is 3 feet. So the first step is to take the number in Mb/s and convert it to MB/s. We pretty much always talk about storage space in terms of bytes, though (mega bytes, giga bytes, and tera bytes). Example Scenarioįor example, let’s say we have 2 hours of footage (120 minutes), we’re converting our footage to Avid DNxHD 175, and we want to know how much storage space we need.Īvid DNxHD 175 footage is 175 Mb/s (isn’t that handy?). If you have two of those three, you can calculate the third. A simple formula describes the bitrate, the file size, and the length of the video. Whether or not the M is capitalized doesn’t matter – just look at the B.Ī video bitrate is the amount of data that the file contains for each second of video. Occasionally (less common) someone will give you the number in megabytes per second (MBps or MB/s). When someone tells you about video bitrates, they usually give you that number in megabits per second (Mbps or Mb/s). Nearly all of the mistakes people make when talking about bitrates come from confusing bits and bytes. Unfortunately, though, some people are not aware of the difference, and they will sometimes use the wrong one. When they’re abbreviated, people use a lowercase b for bits and an uppercase B for bytes. You just need to make sure you know which of them you’re dealing with. To convert between bits and bytes, you multiply by 8 or divide by 8. The concept is simple: One byte is 8 bits. There’s only one thing you need to watch out for, and that is the difference between bits and bytes. This will empower you to be able to work with any type of file or video stream, no matter the format.ĭon’t be scared by all of the numbers involved in calculating video bitrates – anyone can do this. The formulas are at the end of the article, but I encourage you to read through the process, step by step. There are video bitrate calculators out there, but they don’t include every codec, and doing this by hand is actually really simple. What if you’re shooting with a new camera, and you need to know how long your memory card will last you? All you need to know is the bitrate of the camera’s codec and a simple formula. But, if you’re just here for the formulas, you can find them right here.

A codec’s bitrate can seriously affect your workflow, so as a video creator you must be able to understand and calculate video bitrates. This article explains in detail what a bitrate is and how to use it to calculate file sizes, and it’s a follow-up to our huge article on How to Choose the Right Codec for Every Project.
