AJA DataCalc computes storage requirements for professional video and audio media.

Designed for video professionals, this application works with all the most popular industry video formats and compression methods, including AJA Raw, Apple ProRes, DVCProHD, HDV, XDCAM, DV, CineForm, REDCODE, Avid DNxHD, Avid DNxHR, Apple Intermediate, 16 bit RGB and RGBA, uncompressed, and more. Video standards supported include NTSC, PAL, 1080i, 1080p, 720p, 2K, 4K and 8K.

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 including KB, MB, 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 shared via email or other iOS and iPadOS share services, and a Favorites feature allows you to save common calculations for speedy reference.

Great little app from AJA. Great companion TC Calculator and both free. Only thing we need are the DNxHD datarates for AVID. Well done.

Really useful for digital preservation usage

I’ve been using this app on and off for a few years now, calculating file sizes for long term preservation storage. It’s a very useful timesaver.

In the last couple of years a large number of archives have moved preservation files to long term storage on the FFV1 codec (version 3) and it would be amazing if you could add support for this - it would be a real asset for archivists around the world.
