What is a bitrate in video

Bitrate denotes the volume of data transmitted within a specified duration, typically quantified in bits per second (bps). In the context of video, bitrate determines the quality of the video content being transferred or streamed. Higher bitrates mean more data per second, leading to better video quality. Conversely, lower bitrates can cause compression, which may initially degrade video quality despite high resolution and frame rates. Now you know what bitrate is for video, let's see how it is calculated.

How is bitrate in video calculated

Bitrate measures how much data is processed over a certain period and is usually measured in bits per second (bps). Given the significantly greater size of video data compared to audio files, which are generally quantified in kilobits per second (kbps), it is customary to express the data rate for video files in megabits per second (Mbps).

To calculate a video's bitrate, you must know its file size and duration. For example, if you have a video file that is 1 gigabyte (GB) in size and 10 minutes long, you first convert the file size into megabits (since 1 GB equals 8000 megabits). Next, you convert the duration into seconds (10 minutes equals 600 seconds).

A higher bitrate typically correlates with enhanced video quality, as it allows for a greater volume of data to represent each second of the video accurately. However, it also requires more bandwidth for streaming and more storage space.

How does bitrate impact video quality

What does bitrate do in video? Bitrate is key in determining video quality, but it's more complex than always opting for the highest bitrate possible. While a higher bitrate generally leads to better video quality, it also results in larger file sizes. These larger files can cause buffering issues, as many viewers' internet connections and devices may struggle to process large amounts of data quickly.

Finding the right balance is crucial. An insufficient bitrate can lead to degraded video quality, characterized by noticeable artifacts and blurriness. With visible artifacts and blurring. On the other hand, a very high bitrate, although providing excellent quality, might lead to streaming issues and increased storage requirements. The goal is to choose a bitrate that ensures the video is clear and sharp without causing playback problems for the audience.

A higher bitrate enhances image quality, making the video sharper and more detailed. It's particularly important for content creators and streamers who want to provide a professional and enjoyable viewing experience. For instance, Twitch streamers often aim for higher bitrates to ensure their streams look crisp and appealing to viewers, as good visual quality can significantly enhance the overall content.

Factors that impact video bitrate

Here are some factors that impact video bitrate:

  • Video resolution
  • Video resolution indicates the number of pixels in a video frame, significantly impacting bitrate. Higher resolutions, such as 1080p, require more bitrate to maintain quality. For instance, Twitch uses 720p or 1080p for broadcasts. Lower resolutions, like 480p, require less bitrate, making it easier for streamers with slower internet to deliver good-quality streams without buffering.
  • Frame rate (FPS)
  • Frame rate, quantified in frames per second (fps), influences the perception of motion smoothness. Standard frame rates for broadcasts are 30fps and 60fps, with 24fps common in many videos. Higher frame rates like 60fps offer smoother motion, essential for live streaming fast-paced events, though they require higher bitrates. Twitch typically uses 30fps for most streams.
  • Codec selection
  • The codec used to encode video impacts bitrate. Codecs like H.264 and H.265 (HEVC) compress video data differently. H.265 is more efficient, offering higher quality at lower bitrates than H.264. Choosing the right codec is crucial for optimizing video quality and managing bitrate effectively.
  • Video compression methods
  • Video compression affects how data is reduced to lower bitrates. Lossless compression preserves all data, leading to higher bitrates, while lossy compression removes some data to lower bitrate and file size. Lossy compression, used by H.264 and H.265 codecs, balances quality and bandwidth usage for streaming.
  • Lossy video compression

Lossy video compression reduces file size by discarding some data, impacting bitrate. While it lowers bitrate and saves bandwidth, excessive compression can degrade quality. Properly managed, lossy compression maintains acceptable quality at lower bitrates, making it suitable for streaming.

What bitrate should you use

The right video bitrate depends on resolution, frame rate, and viewing platform. Here's a general guideline to help you decide:

For streaming

Platforms like YouTube, Twitch, and Facebook Live have recommended bitrate settings for different resolutions:

  • 720p at 30fps: 2,500 to 4,000 Kbps
  • 720p at 60fps: 3,500 to 5,000 Kbps
  • 1080p at 30fps: 3,500 to 5,000 Kbps
  • 1080p at 60fps: 4,500 to 6,000 Kbps

Higher resolutions, like 1440p and 4K, require significantly higher bitrates to maintain quality.

For uploading

When uploading videos to platforms like YouTube or Vimeo, higher bitrates can be used to ensure the best quality after compression. Here are some recommendations:

  • 1080p at 30fps: 8,000 Kbps
  • 1080p at 60fps: 12,000 Kbps
  • 1440p at 30fps: 16,000 Kbps
  • 4K at 30fps: 35,000 to 45,000 Kbps

Considerations

  • Internet speed: Ensure your upload speed can handle the chosen bitrate, especially for live streaming.
  • Storage space: Higher bitrates result in larger files requiring more storage space.
  • Content type: Fast-paced content with lots of motion may need higher bitrates to avoid artifacts.

Balancing bitrate with resolution, frame rate, and technical constraints ensures you achieve the best possible video quality without unnecessary buffering or storage issues.
