A storage and bandwidth calculator for video and audio media files. StorageCalculator is a simple way to calculate the storage and bandwidth required to store your footage. Also available as an iOS app, it contains data on a wide array of professional codecs, including ProRes, XAVC, DNxHR and RedCode.

Available on the App Store StorageCalculator for iOS requires iOS 10.0 or higher and works on all devices. It is available for free.

Audio and Video Storage/Bandwidth Calculator

You know you'll be shooting on 4 cameras for 3 hours, recording in DNxHD SQ, but how much storage do you need for all that media?

Data Rate Chooser

This tool helps you choose what data rate to use when you know you need to fit a video of a certain duration onto a drive with a certain size. Ideal for encoding MP4s to go on pen drives, but potentially useful for all sorts of jobs.

Copy Time Estimator

The source and destination values below are based on a range of popular products. If your hardware does not match the speed of any of the options you can enter custom values. The device descriptions are rough guides, and actual product performance can vary based on a wide range of factors. There are a number of performance test utilities available which can measure the actual performance of your storage devices.

* Hard drive manufacturers and OS X use the definition 1KB = 1000 bytes, while Windows uses 1024 bytes (a "kibibyte" or "KiB"). Linux usually quotes sizes in kibibytes (but does use the correct unit symbol).
  • 1MiB (1 "mibibyte") = 10242 bytes (1024 x 1024 bytes).
  • 1GiB (1 "gibibyte") = 10243 bytes (1024 x 1024 x 1024 bytes).
  • 1TiB (1 "tibibyte") = 10244 bytes (1024 x 1024 x 1024 x 1024 bytes).
This is why you might find that a 500GB drive only has an apparent capacity of 465GB when you format it (it is really 465GiB).
