Measured video archive storage
Mistake: Using a fixed bitrate merely because the video is labelled HD.
Fix: Measure representative average total bitrate, including audio, and enter that value.

How it works
Estimate archive capacity from measured total bitrate, duration, reserve and copy count.
B = b × 10⁶ × t × 60 / 8; Bₜ = B × n × (1 + p/100)
Use average combined video and audio bitrate measured from representative files. Resolution or codec names do not determine file size. Reserve is an explicit allowance, not a predicted container overhead. Copies multiply storage, not recording duration. No file is uploaded; calculation works offline after loading.

About this tool
Use tool ↑Estimate archive capacity from measured total bitrate, duration, reserve and copy count.
For one copy, multiply average total bitrate in Mbit/s by total minutes and 60, then divide by 8 to obtain decimal megabytes. Multiply by copy count and by 1 plus reserve percent divided by 100. Display both decimal GB and binary GiB; these units describe the same byte count.
