■ EXPORTING

Exporting OMFI Files

Open Media Framework Interchange (OMFI) is a file format that can be transferred to

other platforms and other applications. It was developed primarily by Avid and is sup-

ported by a group of OMFI partners, developers, and software companies that cooper-

ate with the standard to allow import and export of files and information using OMF

formats.

As stated in the Import section, the intention is to allow one digital media appli-

cation to allow the import and export of files and compositions to another. By allowing

the applications to “speak” to one another through importing and exporting, we, the

users, don’t have to deal with extreme measures, third-party software, and any “undoc-

umented solutions” to move media from, say, an editing application to an animation

application.

Acceptance in the marketplace of OMF has been mixed, but one area that imme-

diately embraced OMF was audio. Almost every audio workstation made has some

form of OMF capability. As a result, exporting audio files and compositions through

OMF is quite common.

OMF comes in two flavors: Version 1.0 is supported by older audio workstations

and works quite well in most situations; version 2.0 was developed a little later and

incorporated some changes. The result is that more applications can use OMFI. Once

again, before deciding on whether to use 1.0 or 2.0, the best bet is to call the facility

that will be using the file and talk directly with the engineer who will be using the files.

Once you’ve created a successful test, name the Export Setting for the name of the

facility it’s going to.

Exporting AAF Files

Another form of export is Advanced Authoring Format (AAF), which is very similar in

concept to OMFI and it essentially does the same thing that OMFI does. Using AAF,

you can export sequence information (compositions) compositions with embedded

audio and video media.

The two different standards are based upon the fact that software developers,

like any other committee of persons, cannot agree on everything. Whenever you get

commercial software developers to allow some form of access to proprietary compres-

sion and functionality, it gets a little slippery. Some applications are OMF-compliant;

others are AAF-compliant. Your Free DV and Xpress Pro have both. As long as there is

some method of moving media from one application to another, it’s good, right?

Whether your target application is OMF- or AAF-compliant, the methods of

export are exactly the same.
