Larry - - just remembered this (someone once pointed it out):

http://www.avid.com/dnxhd/widget/storage_calc_widget.html

on Avid's own website. 

Cheers, malcolm

 Thanks very much, Malcolm! That will come in very handy. Wonder why it never came up in multiple knowledge base searches I did for calculators, converters and the like...hmmmmm.

The calculator I linked to above does DNX resolutions?

The storage calculator is currently a direct link off the main page of avid.com... but it is odd it does not come up in KB searches.

The site link has "Widget" in the name... I wonder if this means I can download it, and keep it on my (Mac OS) desktop, as a widget.  

That would seem to make sense, and yet, I see no obvious way to downloading it.

I'll check into this and post back later today.  Malcolm

Never use DV25 under any circumstance.

That goes for acquisition too!
