What is Video Bitrate?

What is video bitrate?
Video bitrate refers to how much data you are transferring via the internet at any given time.

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 favorably 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?

What is video resolution
Video resolution is a measure of the number of pixels that form your video’s frame.

Video resolution and video bitrate are interconnected but are not the same thing. Both factors need 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 image 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

frame rate fps
Frame rate measures how quickly individual frames of your video appear in succession to one another.

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 connection speed at that moment.

You should also ensure your video’s frame rate and resolution are 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.

Mobile Bitrates

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 utilize 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.

Bitrate Technical Explanations

Bitrate Control Techniques

When it comes to video bitrate, there are several control techniques used in different scenarios. Constant Bitrate (CBR) maintains a fixed bitrate throughout, offering consistent quality, but it can be less efficient in terms of file size. Variable Bitrate (VBR) adjusts the bitrate based on the video’s complexity, providing higher quality during complex scenes and saving data during simpler ones. Adaptive Bitrate Streaming (ABR) changes the bitrate in real time based on the viewer’s network conditions, ensuring smooth playback without buffering. In professional broadcasting, these techniques are crucial for balancing quality and performance, with each having its own benefits and trade-offs, depending on the specific application.

Encoding Standards

Video encoding standards like H.264, H.265 (HEVC), and AV1 are central to video delivery. When it comes to H.264 vs. H.265 vs. AV1, H.264 is widely compatible and efficient, making it the standard for many streaming platforms. H.265 (HEVC) improves compression, offering better quality at lower bitrates, which is ideal for 4K streaming. AV1, a newer codec, is gaining traction due to its superior compression efficiency and lower latency, especially in the context of live streaming bitrate settings. As AI video compression technology continues to evolve, newer standards like AV1 are expected to become more common, particularly for low-latency streaming protocols, providing better quality and efficiency across a variety of devices.
