This streaming bitrate calculator takes the figures you already have and applies the relationship behind streaming bitrate calculations for you, giving required upload speed and bitrate from bits per pixel, spare bandwidth, frames per second, height in px, width in px, bits per pixel, spare bandwidth, frames per second, height in px, width in px, simultaneous viewers and one way.
What Is the Streaming Bitrate Calculator?
The streaming bitrate calculator turns bits per pixel, spare bandwidth, frames per second, height in px, width in px, bits per pixel, spare bandwidth, frames per second, height in px, width in px, simultaneous viewers and one way into required upload speed and bitrate.
It is a quick way to get from the numbers you have to the number you need, without setting up a spreadsheet or reaching for a formula.
How the Streaming Bitrate Works
Each result follows from the ones before it, and the calculator shows every step, so a surprising answer can be traced back to the input that caused it.
Round your inputs to the precision you actually know, and keep more precision than that in the intermediate steps.
Getting a Result You Can Trust
Run the calculation twice with slightly different inputs. A sensible calculator moves its output in proportion; a wild change points to a unit or a decimal point problem in what you entered.
Write the inputs down next to the answer. It takes a moment and it is the difference between a number you can explain and one you cannot.
A Worked Example
Working through an example, with bits per pixel set to 10, spare bandwidth set to 5, frames per second set to 2, the calculator returns bitrate of 25,000, and bitrate (sh bit) of 20,000, and required upload speed of 75,000. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out required upload speed?
Enter bits per pixel, spare bandwidth, frames per second, height in px, width in px, bits per pixel, spare bandwidth, frames per second, height in px, width in px, simultaneous viewers and one way. The calculator then works through the relationship and reports required upload speed and bitrate.
What does the streaming bitrate actually calculate?
It takes bits per pixel, spare bandwidth, frames per second, height in px, width in px, bits per pixel, spare bandwidth, frames per second, height in px, width in px, simultaneous viewers and one way and converts them into required upload speed and bitrate using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter bits per pixel?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
