As you may have guessed, the higher the bitrate, the better the quality of your video. Does a higher bitrate mean better video quality? The higher the bitrate, the higher the resolution and frame rate of the video. It is why higher bitrates are essential for streaming videos that are of high resolution. Here are a few things to remember when choosing the right video bitrate for streaming.
Variable bitrate encoding
Streaming video encoding can take several forms, but one is known as variable bitrate encoding. This type of encoding allows the bitrate to be adjusted based on the complexity of the video content, thereby preventing interruptions. Although many broadcasters offer more than one bitrate, they are still a minority in the streaming video industry. For example, while one bitrate requires 2,000 kilobits to stream a second’s worth of video, another requires 3,000 kilobits.
The constant bitrate encoding method requires a fast and stable Internet connection and will not produce high-quality results. In contrast, variable bitrate encoding allows the bitrate to vary and maintain high image quality. The downside of this technique is that the video files may be of variable size, causing buffering and other problems. However, it is important to note that VBR is more efficient in many cases.
Quality of video
Streaming services have a large collection of movies and TV shows highly varied in quality. However, existing databases fail to capture the low-level characteristics necessary to assess video content quality. For example, surveillance footage is usually transmitted in black and white, with 640×480 resolution, which is considerably less than the resolution of a Netflix show played in a living room. These differences may be problematic for the assessment of video quality.
Streaming service providers can deliver videos at the resolutions consumers demand. While 480p resolution is adequate for most standard TVs, it can be low for ultra-high-definition TVs. SD resolutions are the starting point for broadcasters and are the best choice for viewing most kinds of movies and TV shows unless they feature high-definition graphics and fast action. Generally, the highest resolution is 1080p, but lower-resolution formats are suitable for less resource-intensive applications.
Effect of video bitrate on video quality
Video bitrate is the rate at which data is transferred over a given medium. Generally, the higher the bitrate, the higher the quality of the video will be. On the other hand, higher bitrates mean larger video files and slower export. High bitrates also drain bandwidth.
Higher bitrates are recommended for better video quality, depending on the type of content you’re streaming. However, higher bitrates also mean larger video files, which can be difficult to edit. However, higher bitrates will mean higher video quality, so be aware of the drawbacks. If you’re streaming live, you’ll need to consider other factors. High-quality footage will require a higher bitrate, as it uses more data to produce it.
Finding the right video bitrate for streaming
One of the first things you need to know when choosing video bitrate is the video you will stream. A higher bitrate means more information will be transferred, but it will require more storage space. Therefore, video files with a higher bitrate are generally larger than those with lower bitrates. Obviously, the higher the bitrate, the higher the quality of the video. However, you’ll notice that the higher the resolution, the higher the bitrate.
When choosing the right bitrate, remember it’s not an exact science. Bitrate varies according to client connection speed and the quality that’s desired. Higher bitrates are recommended for videos that are destined for higher resolutions. Therefore, consider the resolution if you’re looking to stream a video online. Higher resolutions require higher bitrates and vice versa. If you’re unsure which one is right for your streaming needs, check with your provider for more information.
