AJA DataCalc

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.

App works well but I agree with the other comments about including more codecs - particularly all the flavours of Avid DNxHD (eg 185X) or even better being to create user presets.

I'm trying to work out data rates for a QuickTime I'm making so I found this app after buying another. It is good, but as I found with the other app its more for avid hd codecs, and all I have for ad is dv25. So it's not completely useful for finding out h264 data file sizes. If AJA could just add a custom field to add your known data rate it would be perfect.

This app is handy to have next to your NLE for data rate calculations - BUT, only as a rough guide. Unfortunately a few of the codec data rates are slightly off and therefore are not useable as absolute values. I know AJA will update this app, and look forward to their refinements.

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.

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

Keeps crashing every time I try to use any button

Works well.

I have been using this app probably since “version 1.0” (8 years ago?) It has been my go-to for calculating data rates from the days of SD DVD authoring, through HD 1080p field acquisition, and still going strong as I shoot 4K on my a7s II with VideoDevices outboard ProRes recorder. That’s gotta be some kind of record for longest-running app..? Plus it’s rock-solid and intuitively laid out. A very belated “thank you!!” to the good folks at AJA.

Updated to v3, and was disappointed to find what feels like a v1 beta. UI is stripped to nothing, number fields pull up the full keyboard, slow to launch, typos in the codec selections, and still no Canon XF-AVC listings. I use the app literally every day and it's supposed to be quick and easy--now I want to find another solution.
