What is a Good Bitrate for Recording

Determining the good bitrate for recording digital media is crucial for balancing file size, quality, and delivery requirements. Whether it's audio or video content, selecting the right bitrate can significantly impact the viewing or listening experience.

In this article, we'll explore:

At the end, you will have recommendations for choosing the best audio and video bitrate for your digital media projects.

What is bitrate's definition?

Bitrate refers to the amount of data processed per unit of time in digital communication or multimedia. It's commonly used to describe the quality of audio or video data streams. In simpler terms, bitrate measures how much information is conveyed in a given amount of time.

Bitrate is usually expressed in kilobits per second (Kbps) or megabits per second (Mbps). Higher bitrate in an audio or video typically means better quality and fewer compression artifacts. However, it also requires more storage space and higher bandwidth for streaming.

There are two bitrate types:

  1. Constant Bitrate (CBR). The bitrate remains constant throughout the entire duration of the multimedia file. CBR is often used in applications where maintaining a consistent file size is important, such as live streaming or broadcasting.
  2. Variable Bitrate (VBR). This bitrate allows for more efficient use of data by allocating higher bitrates to complex segments of the media and lower ones to less demanding parts. This results in better overall quality and compression efficiency compared to CBR. VBR is commonly used in applications where preserving quality while optimizing file size is a priority. These include video-on-demand services or music streaming.

Why does bitrate matter for screen recording?

Just as for producing multimedia, bitrate is crucial for screen recording because it directly impacts the quality and clarity of the content.

When you're capturing what's happening on your screen, whether it's for creating tutorials, demonstrations, or gameplay videos, you want to ensure that the recording accurately represents what you're showing.

Here's why video bitrate is important for screen recording:

    1. Quality of Capture. A higher bitrate means more data is being recorded per second. This translates to better-quality video with sharper images, smoother motion, and fewer compression artifacts. This is especially important for capturing detailed visuals, such as text, graphics, or fine details in software interfaces.
    2. Readability of Text. Many screen recordings involve displaying text, such as in tutorials or presentations. Higher bitrate recordings preserve the clarity and legibility of text. Hence, it ensures that viewers can easily read what's on the screen without it appearing blurry or pixelated.
    3. Smoothness of Motion. Screen recordings often involve capturing dynamic content, such as moving cursors, animations, or video playback. A higher bitrate helps maintain smooth motion and reduces the likelihood of blur or stuttering, resulting in a more polished and professional-looking recording.
    4. Retention of Details. Whether it's capturing intricate design elements, subtle color gradients, or small icons, a higher bitrate ensures that the recording retains as much detail as possible. This allows viewers to see the content exactly as it appears on your screen.

Overall, choosing the right bitrate for screen recording is essential to producing high-quality videos that effectively convey the information you're trying to share.

Common bitrates and their applications

Bitrates vary depending on the type of media being encoded, whether it's audio or video. Here are some typical bitrates and their use.

Audio Bitrates

128 kbpsThis bitrate is commonly used for streaming music online, including platforms like Spotify and Apple Music.While it offers decent audio quality, some compression artifacts may be noticeable, particularly in complex or dynamic music.
192 kbps - 256 kbpsThese bitrates provide better audio quality compared to 128 kbps and are often used for higher-quality music streaming or downloading.They strike a balance between audio quality and file size, suitable for listeners who prioritize fidelity but also consider storage or bandwidth constraints.
320 kbpsConsidered near-CD quality. This bitrate offers excellent audio accuracy and is often preferred by audiophiles or individuals who aim for the highest possible sound quality.It's commonly used for music downloads or premium streaming services that offer high-fidelity audio options.

Video Bitrates:

1-2 MbpsThis bitrate range is suitable for streaming standard-definition (SD) video content, such as online clips or video calls.It provides acceptable quality for smaller screens or lower-resolution displays. However, it may exhibit compression artifacts or reduced detail on larger displays.
3-6 MbpsIdeal for streaming high-definition (HD) video content, including platforms like YouTube or Netflix.This bitrate range offers sharper image quality, smoother motion, and fewer compression artifacts, suitable for most viewing environments and screen sizes.
10-20 MbpsUsed for streaming or downloading full high-definition (Full HD) video content, offering even higher quality and clarity compared to lower bitrate streams.This bitrate range is suitable for larger screens or higher-resolution displays, providing immersive viewing experiences with enhanced detail and fidelity.
25 Mbps and aboveReserved for ultra-high-definition (UHD) or 4K video content, offering the highest level of detail and visual fidelity.This bitrate range ensures optimal quality for viewing on large screens or high-resolution displays, delivering stunning visuals with minimal compression artifacts.

These are general descriptions, and specific bitrate requirements may vary depending on factors such as the content's complexity, intended audience, available bandwidth, and playback device capabilities.

How does bitrate affect the file size?

While aiming for the best quality, it's also important to strike a balance between bitrate and file size. Remember, bitrate directly influences the size of video and audio files. Essentially, the bitrate determines how much data is used to represent each unit of time in the media stream.

Higher bitrates allocate more data to encode each second of the media. This results in more detailed and higher-quality representations of the audio or video content. Conversely, lower bitrates use less data per second.

Bitrate calculation

To estimate the size of a media file based on its bitrate, you can use the following formula:

File Size (in bytes) = Bitrate (in bits per second) × Duration (in seconds) / 8

For example, you have a video with a bitrate of 5 Mbps (5,000,000 bits per second) and a duration of 10 minutes (600 seconds). Then, the estimated file size would be: (5,000,000 bits/s) × (600 s) / 8 = 375,000,000 bytes (or 375 MB).

In summary, finding the right balance between bitrate, file size, and desired quality is essential when encoding media for storage, streaming, or distribution.
