This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- Size = [(VideoMbps + AudioMbps/1000) * DurationSeconds] / 8
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Video Bitrate: 8 Mbps
- Audio Bitrate: 192 Kbps
- Duration: 10 Minutes
Expected outputs
- Estimated Size: 0.61 GB
- Size in MB: 614 MB
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- Video bitrate is entered in Mbps and audio bitrate is entered in Kbps.
- Duration is entered in minutes and converted to seconds for the estimate.
- Negative bitrate or duration values are invalid.
Unit handling
- Video Bitrate accepts values in Mbps.
- Audio Bitrate accepts values in Kbps.
- Duration accepts values in Minutes.
- Estimated Size is displayed in GB.
- Size in MB is displayed in MB.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
