## Description

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.

## Review summary

AJA DataCalc is a free, fast tool many professionals rely on for quick data-rate, size, and runtime calculations, with a long history of usefulness and a simple interface. However, multiple reviews report crashes, a troubling UI regression in updates, and data accuracy gaps for several codecs. Key enhancements requested include bitrate calculation, broader codec support, and clearer unit handling. Some users also face compatibility issues with older devices. Overall, it's valuable but plagued by stability and data-accuracy concerns that affect reliability.

### Pros

- Free to use with no paid upgrade
- Fast, easy to use and has a clean, intuitive interface
- Very useful for calculating file sizes, runtimes and data rates across codecs
- Long track record and generally reliable for professional workflows
- Ability to email or share results directly

### Cons

- Crashes and stability issues when interacting with settings or using any button
- UI/UX regression in updates (notably v3) and generally sluggish performance or small controls
- Inaccurate or incomplete data for certain codecs (e.g., DNxHD bitrates, MB vs Mb) and missing codec data
- Missing features and codec support (no bitrate calculation option, limited codec list)
- Compatibility problems with older devices or platforms (e.g., iPod Touch 1G, microphone requirement)
