TIP: If you’re isolating a subject with a complex shape that moves quite a lot,
you might consider using multiple simple overlapping shapes to track and
rotoscope it, rather than a single complicated one, to make the task easier.
7 When you’re finished rotoscoping the window, be sure to click the Clip button to switch
back to Clip mode, so you can trim the window’s shape across every keyframe you’ve
just created, if necessary. This will also prevent you from accidentally adding more
keyframes if you select other shapes.
This technique requires a bit more work then simply using the Tracker, but it’ll let you
quickly adjust the animation of a window to more tightly conform to a moving subject
when you need an adjustment to be specific to that subject alone. You can also use this
technique to reposition specific motion path points in the middle of an otherwise
successful track to make them fit better, or to add keyframes to the beginning or end of
a track when the subject moves offscreen but the window does not.
Viewing a Window’s Motion Path
You can turn on the motion path of the window you’re tracking by choosing Show Track from
the Tracker Option menu, or by pressing the SHOW TRACK soft key on the Center panel of the
DaVinci control panel when you’re in OBJECT TRACK MODE.
