Review the method below for assumptions and conventions.

How to use this tool

  1. Enter combined video and audio bitrate, duration.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Size in decimal GB = bitrate × 10⁶ × minutes × 60/8/10⁹.

A WORKED EXAMPLE

Using combined video and audio bitrate = 50 Mbit/s, duration = 10 minutes, the result is 3.75 GB. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

Constant average bitrate estimate; container overhead is excluded. An ideal geometric or exposure estimate. Lens behavior, stabilization, sensor crop and scene conditions may change practical results.

Common questions

Which inputs does this calculation need?

Estimate file size from total encoded bitrate and duration. Enter combined video and audio bitrate in Mbit/s, duration in minutes. The filled example is editable and is not a saved personal record.

How should I interpret the result?

Constant average bitrate estimate; container overhead is excluded. An ideal geometric or exposure estimate. Lens behavior, stabilization, sensor crop and scene conditions may change practical results.
