AJA has released AJA DataCalc, a free storage requirement calculator for video professionals that runs as an iPhone App. It can be downloaded here.

AJA DataCalc can be used in the field during acquisition, or in the edit bay during post-production, allowing the user to effortlessly calculate their storage consumption and data capturing requirements.

AJA DataCalc supports a wide array of video compression formats such as Apple ProRes, DVCProHD, HDV, XDCAM, DV, RGB and YUV Uncompressed and more. Video standards supported include NTSC, PAL, 1080i, 1080p. 720p, 2K and 4K.

The application features a user interface where most settings can be entered with a simple finger scroll through lists of the most common file format configurations. Durations can be entered in units of days, hours, seconds or even in a precise time code frame count. A 'More' button allows the user to further select and specify frame rates, frame sizes,
compression type; or in the case of audio: sample rates and bits per sample. From the 'More' page, press on the 'Information' icon to get to a 'Summary' page to review results and have the option to deliver the data via email.
