  the new eSpace app vs. AJA Data Calc

  Posted by Bob Zelin on November 3, 2016 at 5:30 pm

  Hi –
  I became aware of this free Apple App Store app, from the SAN Networks Forum on Cow.
  eSpace is an IOS only app that is much more robust than AJA Data Calc. It lets you scroll thru
  countless resolutions from NTSC all the way to 8K Red Full Frame, and everything in between, including
  all the RED, Arri, UltraHD and Go Pro stuff, frame rates from 23.98 to 120 frames per second, and compression codecs that include AVID DNx, DPX, all the ProRes including 4444 XQ, and all the Redcodes.

  Once you select what you are using it shows you instantly the bandwidth in both Mb/sec and MB/sec and lets
  you easily calculate how many Terabytes you will use based on the amount of time (minutes, hours) of footage that you have.

  With all the crazy formats and variations out there today, this is the most comprehensive tool that I have found.
  And its FREE ! I just wish their was an OS X or macOS App store version I could download to an editing computer.

  The only way I can figure out how to find this app, is by typing in the developers name – Alex Mcalpine, on the search window of your App store. If you type in eSpace, you see other products, but not this one.

  BTW one thing which is cool about this app, is that you can calculate the storage bandwidth requirements for playing multiple codecs in parallel. Not sure if this is advertised or the guys at eSpace designed it to work like this, but this is good for when I need to figure out calculations like this.

  For example if you wanted to confirm the storage bandwidth required to play the following streams in parallel,

  12 streams of Pro Res Proxy, HD, 24 frames
  12 streams of Pro Res HQ, HD, 24frames
  2 streams of DPX 10bit RGB, UHD, 24frames

  The answer is 1.8362 GB/s which is the at the bottom of the app or 1880.2 MB/s (1.8362*1024)

  Tab 1

  Choose codec Pro Res Proxy, HD, 24 frames
  Press the “SEC” button and enter 12
  Then press “MB” button
  Total = 58.7MB/s

  Tab 2

  Choose codec Pro Res HQ, HD, 24 frames
  Press the “SEC” button and enter 12
  Then press “MB” button
  Total = 265.5MB/s

  Tab 3

  Choose codec DPX 12Bit, UHD, 24 frames
  Press the “SEC” button and enter 2
  Then press “MB” button
  Total = 1556MB/s
