X2Pro will create a single AAF file that contains your project information as well as either all of the audio used by the project or references to the audio. Audio clips can be copied whole into the AAF file or trimmed with handles, giving maximum flexibility (the trimming/handles is feature is not available in X2ProLE).
X2Pro will split any multi-channel audio files into separate channels in the AAF file, for example, when a stereo music track is used on your Final Cut project, the left and right channels will appear on two separate tracks in Pro Tools.
Final Cut Pro X uses the magnetic timeline in order to layout a project, while within AAF a composition is constructed from a number of fixed tracks. In AAF, each track is a single (mono) channel of audio. The first thing that X2Pro does is to group and sort everything by its role within the Final Cut Pro X project. This results in tracks in the AAF file also being grouped by role, typically dialogue first, then effects and music. There are options for the user to be able to create their own role order, ignore some roles entirely, and to ignore subroles when laying out the tracks so that all the subroles of one role will be packed onto as few tracks as possible (this feature is not available in X2ProLE).
Within each role, X2Pro analyses the Final Cut project and places the clips on tracks in a logical fashion, usually creating several tracks in the AAF file from each role. Final Cut Pro project components will be rearranged during the conversion process:
In these cases, where necessary, extra tracks are created in the AAF file, so the AAF file will often contain many more tracks than the Final Cut Pro X project appeared to have. Each track will contain clips from just one role and will be named accordingly, for example "A24 (effects)".
X2Pro supports volume adjustments (including key-framed volume adjustments), transitions and fade handles. These are converted as follows in Pro Tools:
