eSpace by @ElephantSpeed allows you to calculate disk storage space for video camera codecs and formats.

If you are working with more than one codec, you can calculate up to 4 codecs in parallel, to give you the total space required for all codecs.

Pro Res, DNxHD, DNxHR, XDCAM, GoPro, AVC LongG, XAVC, H264, RED, DPX, CinemaDNG plus more.

Don't see a codec you need? Tweet us and we will add it or even better you can enter your own custom codec rate in MB/s or Mb/s

I don't know where I would be without it!

The app has a very comprehensive set of formats, codecs and options making perfect for any camera operator, DOP or techie working in broadcast, post and video generally.

Just what I needed to help plan my project requirements. I don't have lots of storage, so this helps define what codecs will work best on a project by project basis. Great work guys.

Nice App! Can't believe its free

Perfect & calculating multiple codecs in parallel is a game changer. 8K RED support already!? I would pay money for this app. Thanks guys
