What is Video Bitrate Calculator?
Video Bitrate Calculator helps you work out a video bitrate for a target file size and duration.
The main result is available video bitrate, with a breakdown of total bitrate. The formula, example and assumptions below explain how to interpret it.
How to use Video Bitrate Calculator
Use the example to get familiar with the form, then enter your own figures. Any rates in the example are illustrative. Check the field labels and units before calculating.
- Gather target file size (MB), duration (seconds) and audio bitrate (kbps). Use values from the same situation or reporting period.
- Replace the example target file size with your own value, then complete the other fields. Check the displayed units.
- Select Calculate and read available video bitrate with its result breakdown. Change one input and calculate again to compare a second scenario. Reset restores the original example.
- Enter target file size in MB, at least 0.001. Decimals are accepted.
- Enter duration in seconds, at least 0.001. Decimals are accepted.
- Enter audio bitrate in kbps, at least 0. Decimals are accepted.
Video Bitrate Calculator: a worked example
With the inputs below, the result is 6,474.666667 kbps (available video bitrate). Follow the example, then replace these illustrative values with your own.
| Input or output | Example value |
|---|---|
| Target file size (MB) | 100 MB |
| Duration (seconds) | 120 seconds |
| Audio bitrate (kbps) | 192 kbps |
| Available video bitrate | 6,474.666667 kbps |
| Total bitrate | 6,666.666667 kbps |
Understanding the Video Bitrate result
Read available video bitrate alongside total bitrate. These describe different parts of the same calculation.
Displayed results use a readable number of decimal places. When checking a result by hand, keep extra precision until the last step. To compare scenarios, change one input at a time and keep the others fixed.
- Example Total bitrate: 6,666.666667 kbps
Video Bitrate Calculator: assumptions and common mistakes
A useful estimate starts with the right inputs. Check the following assumptions and limits before applying the result to your situation.
- Match numerators and denominators from the same reporting period. Creator RPM is revenue per thousand views, while advertiser CPM measures spending.
