You can export a board as an edit to an AAF file that can then be imported into editing systems such as Avid's Media Composer or Adobe's Premier.
For this to work Edit Board needs to know the media IDs that are being used in the editing system. See Linking Edit Board to Media Composer for how to configure your board correctly.
If you have a board containing many nested pages Edit Board always exports the current page that you are on as well as all of it's sub-pages.
From the Export menu at the top of every board select AAF then select export.
