IVideo file size calculations

A. Explanation of the formula to calculate file sizes

Understanding how to calculate video file sizes is essential for managing and optimizing your video content. The formula to calculate the file size of a video is:

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

This formula takes into account the bitrate, which is the amount of data processed per unit of time, and the duration of the video. To convert the file size from bytes to megabytes (MB), divide the result by 1,048,576.

For example, let’s say you have a video with a bitrate of 5 Mbps (5,000,000 bits per second) and a duration of 60 seconds. The calculation would be as follows:

File Size (in bytes) = 5,000,000 x 60 / 8 = 37,500,000 bytes
File Size (in MB) = 37,500,000 / 1,048,576 = 35.86 MB

This calculation gives you the estimated file size for a video with a specific bitrate and duration.

B. Example calculations for common video formats and resolutions

The file size of a video depends not only on the bitrate and duration but also on the video format and resolution. Here are some example calculations for common video formats and resolutions:

1. Standard Definition (SD) video: Let’s say you have an SD video with a bitrate of 2 Mbps (2,000,000 bits per second) and a duration of 180 seconds (3 minutes):

File Size (in bytes) = 2,000,000 x 180 / 8 = 45,000,000 bytes
File Size (in MB) = 45,000,000 / 1,048,576 = 42.97 MB

2. High Definition (HD) video: If you have an HD video with a bitrate of 4 Mbps (4,000,000 bits per second) and a duration of 300 seconds (5 minutes):

File Size (in bytes) = 4,000,000 x 300 / 8 = 150,000,000 bytes
File Size (in MB) = 150,000,000 / 1,048,576 = 143.05 MB

These examples demonstrate that higher resolutions and longer durations result in larger file sizes. It’s important to consider these factors when optimizing videos for online platforms, as larger file sizes can impact upload and playback speed.

Understanding video file size calculations can help you make informed decisions about video encoding, compression, and storage.
