Interpolate
The controls in the Interpolate section provide ways of dealing with occlusions, or objects that temporarily
obscure features that you’re tracking.
By marking a hole the middle of two successfully tracked sections of a clip, you can interpolate a motion
path to fill the gap so that the vignette moves smoothly from the point where tracking is lost to the
point where tracking is found once again. These features require the tracker to be in Key Frame mode;
see the Adjust section below.
Rev: After using the Mark button to specify the beginning of a gap in
tracking data, you can move the playhead to the last frame of the
gap and click Rev to interpolate a motion path to fill the gap.
Fwd: After using the Mark button to specify the end of a gap in tracking
data, you can move the playhead to the first frame of the gap and
click Fwd to interpolate a motion path to fill the gap.
Between: After using the Mark button to specify both the beginning and
end of a gap in tracking data, click Between to interpolate a
motion path to fill the gap.
Mark: Lets you mark the beginning, end, or both of sections of a clip
where a feature being tracked is hidden. Once a clip has been
marked in the Viewer, you can use the Rev, Fwd, or Between
buttons to interpolate an animation motion path to fill the gap in
tracking data. Viewer marks appear as vertical yellow lines in the
tracking bar underneath the transport controls
For more information, see “Using the Interpolate Commands” later in this section.
