Choosing an import format: AAF vs OMF I am developing a video rendering application. I would like to import editing projects from non-linear video editing application like Avid or FCP.

Which format should I start with, AAF or OMF? What would be the pros and cons of either?
AAF is the newer and more complete framework.  It is the successor to OMF, which still lives on but mostly because of legacy applications.

Note that Automatic Duck makes a line of highly-regarded tools that help with import and export of these interchange formats and have recently been made available for free.
