How to use the video file size calculator
- Duration (minutes): Video duration.
- Video bitrate (Mbps): Average video bitrate in megabits per second.
- Audio bitrate (kbps): Average audio bitrate in kilobits per second.
- Select the button and review the result.
Worked example
Ten minutes at 8 Mbps video plus 192 kbps audio is about 614 MB.
Method and limitations
Duration × combined bitrate ÷ 8.
Variable bitrate, container overhead, multiple audio tracks, and metadata change actual size.
Common questions
Why might another result be different?
Inputs, rounding, policies, rates, and assumptions can differ. Compare like-for-like values and use current official information when a rate or rule can change.
