To allow fine adjustment of an image when using Corner Pinning, the View
Through (View Thru Enable) feature allows you to temporarily (for editing
purposes only) reduce the opacity of an iDPM channel to let you “look
through” the image to align the corners precisely with the background.
Corner Pinning and Cropping
Corner Pinning is designed to work in conjunction with cropping. Each
time Corner Pinning is turned on, the pinned corners will be adjusted to
match the current iDPM crop settings. After pinning the corners of an
image you can crop it to select the exact portion of the source video to
display in the corner pinned area.
For example, your source video could contain two people, but you may
want to fly the image of only one person (
Figure 205 ). In this case, you
could build an effect, turn on Corner Pinning, use crop mode, and leave the
corners at the defaults. If you now move the crops maintaining the original
aspect ratio (4x3 or 16x9) you can position these crops so that only the
desired person is shown. If the person or the camera moves, you can adjust
the user crops to keep the person centered between the edges of the crops.
This will result in the person being centered in the video and the effect can
be flown around the screen.

Note Toggling Corner Pinning on and off will reset the corners to the current crop
values and change the pinned corners.
