Video storage calculator
Estimate video file sizes from bitrate, duration and the number of recordings.
Enter your values or select local files.
Use the total audio and video bitrate. This is an estimate: variable bitrate and container overhead can change the result. Resolution alone does not determine file size.
Formula
GB = Mbps × 1,000,000 × minutes × 60 × recordings ÷ 8 ÷ 1,000,000,000.
Worked example
20 Mbps × 60 minutes × 3 recordings = 27 GB.
How to use this tool
