To clear the scale and aspect ratio settings of a clip in the Timeline:
1 Open the standard definition sequence clip in the Viewer by double-clicking it in
the Timeline.
2 In the Viewer, click the Motion tab.
3 Next to the Basic Motion settings, click the red x to reset the scale settings, or type 100
in the number field labeled Scale.
4 Next to the Distort settings, click the red x to reset the aspect ratio settings in the
number field labeled Aspect Ratio.
Downconverting High Definition to Standard Definition Video
High definition video frames are larger than standard definition frames, and they have
a wider aspect ratio. Any method of converting HD media to SD is known as
downconverting.
It is more common to downconvert an entire HD sequence to SD as opposed to using
individual HD clips in an SD sequence, but in both cases you need to choose how the
higher resolution 16 x 9 HD frame is placed in the lower resolution 4 x 3 frame.
You can also downconvert your high definition video within Final Cut Pro by nesting
your HD sequence within an SD sequence that matches your output format. For
example, if your output format is DV NTSC, nest your DVCPRO HD sequence in a DV
NTSC sequence.
Some particular techniques for downconverting HD video to SD are listed below.
