AJA DataCalc allows you to change settings and calculate storage requirements in a single screen with simple controls and a clear concise display. Media durations can be entered in units of days, hours, seconds, or even as precise as frames using time code mode. Clicking on results will rotate you through alternative values whether GB or TB for storage calculations or time results in a variety of formats when in TimeCalc mode. Summary information obtained by DataCalc can even be optionally emailed and a brand new Favorites feature allows you to save common calculations for speedy reference.

Great Tool


With the availability of digital cinema cameras, a tool like this is indispensable. It works as advertised and presents a simple yet elegant graphic user interface. My only wish is that in they offer Compressed CinemaDNG (raw) for the Blackmagic Design Pocket Cinema Camera (BMPCC) as one of the selectable codecs. The BMPCC is rapidly becoming a go to camera for indie filmmakers and it has a vibrant community pushing quality work on it. Great app!

Great new look


Very useful tool
The latest version has a much improved
User interface
Suggestion: would like the storage space to always be in Bytes regardless
Of data rate units

Great datacalc app!!!


I really love this app. For anyone in the tech side of the content ecosystem, this is an ideal app in figuring out file size and runtime when dealing with various codecs, formats, file size selections, etc.

If only it had a bitrate option to calculate also, that would make it a 5-star!!!
