Composition properties are displayed in the property editor when no segment or overlay is selected, as indicated by their rugged texture (to deselect a selected item, click the segment area of the Trackline panel outside segment bars).

You can adjust composition properties at any time, even during actual tracking. All changes of property values are undoable.

All properties inside the Export group relate only to data export from PatchMaker, and changing their values has no visible effect when working in PatchMaker.

True framerate of the underlay and overlay footage. Correct setting of this value is important only if motion parameters are going to be exported to an AE composition (see Mistakes in transferring motion).

To adjust the playback framerate inside PatchMaker, use the Time|Frame Rate menu commands instead.

Admissible inaccuracy in transferring transformations to AE (in pixel units).

Greater values decrease the number of motion interpolation keyframes created in AE and significantly speed up data transfer by direct communication to AE versions preceeding 6.0.

The value of 0 means that transformations will be transferred exactly by making all frames in the AE composition the keyframes.

A nonzero value X means that the maximum inaccuracy in displacement of any pixel in any frame (including invisible pixels outside the mask and the overlay) will not exceed X pixels.

Aspect ratio of rectangular pixels in the underlay and the overlay. Setting this value is important only if you are going to upload transformations to an AE composition (see Mistakes in transferring motion).

This property does not affect motion parameters computed by PatchMaker.

Defines in what form the computed transformations are to be exported and applied to an AE composition (more...).

Number of the first frame in the composition. Changing this value affects frame numbering in the time ruler.

Purpose of motion tracking.

When set to Motion Tracking, the overlay will move just like the underlay and can be applied as a patch.

When set toMotion Compensation, the underlay will undergo inverse transformations so that the masked region remains steady.

Rrange of frames in the composition for playback and final rendering
