BitCalc Lite is a free bitrate calculator app for Android.

BitCalc Lite allows you to quickly calculate duration, filesize and bitrate for video encoding projects. Specify two of the parameters and BitCalc Lite will calculate the third. This allows you to calculate bitrate from duration and file size, calculate file size from duration and bitrate or calculate duration from file size and bitrate. These calculations are vital when you are encoding video and need to determine what bitrate or filesize you need to specify in your encoding settings.

It allows you to change the units used for time (seconds, minutes and hours), size (kilobyte, megabyte, gigabyte) and rate (kilobits per second, megabits per second, gigabits per second).

In order to keep the app simple but versatile it deals with bitrate as a total. Remember that your total bitrate is a combination of your audio and video bitrates. BitCalc Lite calculates a total bitrate which you must split into video and audio as required.

Popup ImageFor example if you calculate a bitrate of 800kbs you must subtract your audio bitrate to determine your video bitrate.

Most video formats will also include some header information so the total file size generated by your encoding process may be slightly different to that shown in BitCalc Lite.

I would always recommend encoding a few versions of your video at various bitrates so you can compare the results as there is no right or wrong answer when it comes to selecting a bitrate. Ultimately you have to decide what is acceptable and what the audience of your video is going to accept.

Future updates:

- Ability to select a size from list of media pre-sets including CD and DVD.
- Ability to switch between 1 KB=1000 bits and 1 KB=1024 bits
