Target File Video Bitrate Calculator
Estimate the video bitrate budget for a chosen file-size limit.
Your inputs
Calculation results
Formula & assumptions
Video bitrate = size budget × (1−overhead) × 8/duration − audio bitrate.
Values use the specified units. Calculations use floating-point arithmetic. Check input measurements and formula assumptions before applying the result.

Example
File-size limit: 100 MiB Duration: 5 minutes Audio bitrate: 128 kilobits per second Overhead allowance: 2 percent Video bitrate · kilobits per second: 2612.2786 Total media bitrate · kilobits per second: 2740.2786
Questions & answers
What does Target File Video Bitrate Calculator calculate?
Estimate the video bitrate budget for a chosen file-size limit.
Which units should I enter?
File-size limit uses MiB. Duration uses minutes. Audio bitrate uses kilobits per second. Overhead allowance uses percent. Convert values to these units before calculating.
Which formula does it use?
Video bitrate = size budget × (1−overhead) × 8/duration − audio bitrate.
What does the included example show?
File-size limit: 100 MiB; Duration: 5 minutes; Audio bitrate: 128 kilobits per second; Overhead allowance: 2 percent. Result: Video bitrate · kilobits per second = 2612.2786; Total media bitrate · kilobits per second = 2740.2786.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
