Video Bitrate: What Is It & How Do You Choose?
In today’s fast-evolving consumer landscapes, video has emerged as a popular medium to resonate with most audiences. Video can be used to deliver exciting and informative messages, where you can capture everything you need to draw the attention of and communicate with the viewer.
Let’s set the scene: You’ve devised a video content strategy, gathered your steaming equipment, and elected to use a video hosting platform that best suits your ambitions.
You’ll probably be excited by the prospect of planning content for each of your videos and executing your ideas to perfection. However, it’s also important to consider how you’re presenting content to optimise your audience’s viewing experience.
Video quality is an essential yet often overlooked aspect of any successful video strategy. According to research, 62% of people are more likely to have a negative perception of a brand after watching its low-quality video. With this being said, creating a breathtaking viewing experience can make a vast difference in captivating prospective customers.
One way to ensure you’re serving the crispest, highest-quality content to your audience is to choose the optimal video bitrate for your streaming needs. But what is bitrate and how exactly can it alter the success of your project? Before we look at optimal video bitrate and how it differs from video resolution, let’s start with a baseline definition:

What is Video Bitrate?
Every piece of digital content you produce will be made up of bits. Video bitrate refers to how many units of data a video can process or transfer. Once you’ve finished a video and it’s ready to process, if you choose a low bitrate it might get compressed regardless of how high the resolution and frame rate were at the start. With this being said, it’s essential to choose a high bitrate to maintain a high-quality, seamless streaming experience with fluid viewing.
By implementing a bitrate that’s high enough to move your data over the internet, your viewers will benefit from a smooth, reliable stream. Benefiting from clear information and visuals, your viewers will be more likely to act favourably if they have a positive impression of your business.
In essence, bitrate is the speed at which your video content uploads to the internet from your camera or server. It is also the speed at which your viewers can download your video. Bitrate is usually measured in Megabits per second (Mbps), a figure that represents the volume of bits uploaded to and downloaded from the internet each second.
What is Video Resolution?
Video resolution and video bitrate are interconnected but are not the same thing. It’s important for both factors to be aligned for a successful outcome.
Video resolution refers to the number of pixels that form a video frame to create an image on a screen. The more pixels a video has, the higher its overall quality will be. However, If you only think about video quality in terms of resolution, you’ll be missing half the picture.
Videos with high resolution require a high bitrate because they’ll require more data to move more pixels. Therefore, with a high resolution that matches your high bitrate, you can reach your viewer more effectively and with greater reliability.
A Guide to Video Bitrates
You’ll be encouraged to produce high-resolution videos for your target viewers that require a high bitrate to stream successfully.
You should also consider the differences in internet speeds between consumers.
The bitrate you choose will largely depend on the internet connections of your end users. Though releasing videos with high bitrates can be extremely valuable, it’s important to account for those who might have to contend with lagging videos and constant buffering.
You should always tailor the bitrate of your videos to the demands/expectations of your target audience. A great way to meet differing demands is by releasing videos in different bitrates so that those with slower internet connections can digest content accordingly.
Bitrates, Encoding & Frame Rates
You should select an applicable bitrate after you’ve completed your video and reached the encoding process. Upon doing so, your video encoder will ensure your file is compressed correctly.
You can release multiple versions of your video with different bitrates. This will increase the availability of your video to various users and you won’t need to transcode multiple versions of your video at different bitrates either.
Multi-bitrate streaming is a great way to make multiple copies of your video at different bitrates. Viewers can then select a viewing quality that’s suitable for their device. Alternatively, with adaptive bitrate streaming, they’ll receive the highest-quality version of your video based on their internet speed at that moment.
You should also ensure your video’s frame rate is high enough to prevent jerky, slow videos that fail to meet their intended purpose. Though there’s no optimal frame rate, if you’re shooting moving shots you should focus on a higher-frame rate to keep your audience engaged.
In today’s mobile-driven consumer landscapes, it’s vital to consider the bitrate of videos streamed on mobile devices. Live streaming from mobile devices can be unpredictable, but you can accommodate this by providing video files at bitrates that stream well on mobile devices.
You can utilise multi-bitrate streaming to provide a wide range of bitrates in your videos and reach considerably more people. Viewers can then choose the best quality video available to their device at a given time.
