CHAPTER 11 310
Producing Final Video
•
Select Scale To (frame size) if you cropped the video and want to enlarge the cropped frame
to match the Frame Size you specified in the Video Settings panel. Deselect this option if you
want the video to be exported at the cropped size.
•
Drag the slider under the frame to preview how the current Special Processing options affect
other frames.
•
Select Noise Reduction to increase compression efficiency by reducing variations in pixel
values. From the Noise Reduction menu, select Blur for a subtle blur, Gaussian for a stronger
blur, or Median for a blur that attempts to preserve sharpness at edges. This option does not
apply noise reduction to audio.
•
Select Better Resize if you specified cropping or scaling in this dialog box and want Premiere
to use its own high-quality resizing method. Deselect to let the codec you selected perform
resizing; many codecs resize faster but at the expense of picture quality.
•
Select Deinterlace to remove the secondary field from interlaced video and interpolate the
lines of the dominant field. Deselect this option to deinterlace using the methods built into
Video for Windows or QuickTime, which are not as effective as the method Premiere uses.
•
Select Gamma to specify a value by dragging the slider. Gamma adjusts midtones while
preserving the lightest and darkest parts of the picture. This Gamma option is intended to
help compensate for differences between video display characteristics of different platforms.
A gamma value of 1.0 changes nothing; a value of 0.7 or 0.8 is recommended for cross-
platform playback.
•
Click Reset if you want to revert to the settings that were in use before you opened the Special
Processing dialog box.

Click OK to close the Special Processing dialog box, then click OK to close the Settings dialog
box. Specify a location and filename, and click OK. If you want to cancel exporting, press Esc;
it may take several seconds to complete the cancellation.
You can use the Save and Load buttons in the Export Movie Settings dialog box to save
and later quickly load export settings you frequently use. Loading saved settings is partic-
ularly useful when you create several types of video files (for example, NTSC and Web video)
from the same project.
