If you're in the business of video hosting, you know that bandwidth is a crucial factor in delivering high-quality video content. When it comes to hosting videos over the HLS (HTTP Live Streaming) protocol, accurately calculating bandwidth usage is essential to avoid buffering and ensure uninterrupted video streaming. In this comprehensive guide, we'll discuss how to calculate bandwidth usage for HLS video hosting and help you optimize your video streaming experience.
While there are many online bandwidth calculators available, it's important not to rely entirely on them for video hosting. There are several variables to consider when calculating bandwidth usage, and most calculators don't take all of them into account. Instead, use them as a reference and follow the tips in this guide to get a more accurate estimate of the bandwidth required for your video hosting needs.
The amount of bandwidth required for video hosting depends on several factors, including video resolution, bit rate, frame rate, audio quality, and the amount of action in the video. Videos with heavy action, such as action movies, require more bandwidth than videos with less action, such as training videos, as the former has more data to transmit due to the constant changes in the content.
Bitrate of the video transcoded to HLS will not always be whatever you set it to be. It's essential to keep in mind that the actual bitrate of the video may be either less than or equal to what you have set for encoding. This is because the bitrate of a video depends on its content, and videos with high motion and more complex scenes will require a higher bitrate for proper encoding. On the other hand, videos with fewer changes in content and slower motion require less bitrate for proper encoding. Therefore, when calculating the bitrate for video hosting, it's essential to consider the content of the video, and it's advisable to set the bitrate to the maximum value that is practical for your video's content to ensure high-quality video streaming.
To calculate bandwidth usage for HLS video hosting, you need to consider the following:
To calculate bandwidth usage for video hosting, you can use the following formula:
Bandwidth (in bits per second) = (video bit rate + audio bit rate) x 1.2
The formula assumes that the video is encoded using H.264 and that there's a 20% overhead for the data transmitted.
In conclusion, bandwidth calculation is essential to ensure seamless video streaming for video hosting. By following the tips in this guide and using the provided formula, you can accurately calculate the bandwidth required for your HLS video hosting needs and optimize your video streaming experience.
