AVID QUICKTIME AMA

AMA stands for Avid Media Access. Simply stated, this is a set of features which allow

one to edit with files without having to import or ingest them first. Instead, we link to

these external files. Using AMA, a supported file can be opened, screened and used for

editing without needing to import it or create new media in an Avid proprietary format.

AMA also adds native codec support, and currently allows us to use P2, XDCAM, GFCam,

Canon and RED files without conversion within the Avid environment.

From their beginning Avid editing systems have been able to import QuickTime movies

and also export edited material as QuickTime files. QuickTime has proven a quick and

effective way to share media, particularly between Avid systems and the Graphic world.

Avid has gone so far as to develop (and distribute, free of charge) its own QuickTime

codecs so Avid format QuickTime movies can be used on any PC or Mac with the codecs

installed.

This document is about the next step in QuickTime support in Avid editing systems. You

can access and play QuickTime movies directly, wherever they are stored. A few

benefits of this new feature include:

 Screen QuickTime files quickly inside the Avid editing system, without having to

leave the editing system or start another program

 Give an outside department control over some aspects of show content by

having them create and manage QuickTime files you are editing with

 Automatic updating of program elements (such as After Effects animations)

when they are redone (subject to certain guidelines)

 Easier exchange of material between various editing systems such as Apple Final

Cut Pro and Adobe Premiere.

QuickTime AMA codec officially supports any QuickTime movie which will play in the

Apple QuickTime player.
