## What is AJA DataCalc?

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.

### 4/5 — Helpful but lacks older devices

*2024-11-28, version 4.5.0*

Really helpful to keep an eye on storage space requirements. Just sad that older devices like Ki Pro, Ki Pro mini and Ki Pro Quad are absent from the device selection.

### 1/5 — Crashes with iOS 17.

*2023-10-14, version 4.5.0*

This was a handy app for checking run time but crashes now. Was inputting a 240 gig drive and then went to select other functions and it instantly crashes. Deleted and reinstalled but no happiness. Sad, was helpful while it worked.

### 1/5 — ios 17 crashes

*2023-10-11, version 4.5.0*

App crashes as soon as I touch a setting. Please fix.

### 1/5 — App Needs to be Updated

*2023-09-19, version 4.5.0*

Keeps crashing every time I try to use any button

### 1/5 — 누르면 꺼짐

*2023-09-19, version 4.5.0*

누르면 꺼짐

### 5/5 — Great tool

*2023-09-07, version 4.5.0*

Works well.

### 5/5 — HDV bit rate wrong

*2021-11-05, version 4.5.0*

I use this app a lot. I just noticed today that the HDV bit rate is set at 1.5 Mbps. I use DV25 instead, but that error should probably be fixed.

### 5/5 — Really useful for digital preservation usage

*2019-11-22, version 3.0.1*

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.

### 5/5 — Ray Caniffi

### 4/5 — Does the job

*2019-08-30, version 3.0.1*

My feedback for the devs: it has some flaws. The resolutions dropdown MUST describe actual dimensions and not just the name “4K FULL”. Hard to compare results from different sources when terminology changes and I still can’t work out what size “4K FULL” is supposed to be. Clarity is a key step on the way to accuracy. 

An on/off switch for audio would be more helpful than manually selecting “0 ch” to show the result without audio included. Some defaults are strange: first time using the app and it chose 14.98 FPS and 8-bit 32 kHz audio as the default, there are more common default combinations which are applicable to more people (like 23.98 FPS and 24-bit 48 kHz audio). 

Compliments: being able to enter a specific TC duration is a fantastic and simple idea, which other calculators haven’t considered. Good job.
