When to use this calculator
Use the available bitrate to plan export settings, recognising that quality also depends on codec, content and resolution.

PUTTING IT INTO PRACTICE
Video Bitrate: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Target file size (MB) | 600 |
| Duration (minutes) | 10 |
| Result | 8 Mbps |
- Check the input labels and enter the example values above.
- Apply the relationship: Average bitrate (Mbps) = file size × 8/(minutes × 60).
- The result is 8 Mbps, rounded for display.
How to interpret your result
This is a total bit budget; audio and container overhead reduce the portion available for video.
Uncompressed pixel and PCM estimates use a predictable data layout. Compressed media sizes depend on codec and content. Average encoded bitrate can estimate file size but does not by itself establish quality.
Frequently asked questions
Will an uncompressed image estimate match a JPEG file?
Usually not. JPEG uses compression, so its final size depends on the image and encoding settings.
When is the video bitrate calculator useful?
Use the available bitrate to plan export settings, recognising that quality also depends on codec, content and resolution.
How do I use the video bitrate calculator?
Enter target file size (mb), duration (minutes). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Average bitrate (Mbps) = file size × 8/(minutes × 60).
What should I check before using the result?
This is a total bit budget; audio and container overhead reduce the portion available for video.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
