Apple Final Cut Pro 7 - Manual (Page 1487)

Creating Artificial Pans in 16:9 Footage
In some complex scenes with multiple characters or centers of visual activity, an artificial
camera move (a pan) can be introduced to recenter the widescreen action within the
4:3 frame.
In Final Cut Pro, you can crop and even perform simple pans by animating the Center
parameter in the Motion tab. However, unless the animation is convincing, this can be
more of a distraction than anything else. For more information on using the Motion tab
and animating parameters, see
“Changing Motion Parameters” and “Animating Motion
Effects Using Keyframes.”
16:9 Anamorphic
You can use this method to preserve the 16:9 aspect ratio of HD video when scaling down
to SD video. 16:9 anamorphic video squeezes a 16:9 image within a 4:3 aspect ratio, and
the image is stretched during playback so it appears normal. Some DVD players and video
monitors have an option to unsqueeze anamorphic video.

To squeeze a 16:9 clip within a 16:9 anamorphic sequence
1 Create a sequence with a 16:9 anamorphic aspect ratio. For example, choose the DV-NTSC
Anamorphic or DV-PAL Anamorphic Easy Setup and then create a new sequence.
2 Drag a clip with a 16:9 aspect ratio to the sequence.
If a dialog appears asking if you want to conform your sequence settings to your clip,
click No.
The 16:9 sequence clip is now scaled to fit in the anamorphic 16:9 sequence, and the
aspect ratio of the 16:9 clip is preserved even though you are working in an SD sequence.
For more information about anamorphic video, see “Working with Anamorphic 16:9
Media.”
