Apple Compressor 3 - Manual (Page 272)

For general information about deinterlacing, see About Deinterlacing .
Important: Using all Best settings may result in unexpectedly long processing times.
If you are reducing the frame size in addition to deinterlacing the frame, Fast or Better
will likely provide sufficiently high quality, depending on the amount of downward
resizing.
Note: While the Deinterlace pop-up menu is always active, Compressor only deinterlaces
jobs that need it. (For example, if the source is interlaced and the Output Fields pop-up
menu is set to Progressive, Compressor will deinterlace. If the source media file is
progressive, Compressor will not deinterlace.)
• Fast (Line averaging): This option averages adjacent lines in a frame.
• Better (Motion adaptive): This option offers good-quality deinterlacing for areas of
the image that are in motion.
• Best (Motion compensated): This option offers higher-quality deinterlacing for areas
of the image that are in motion.
• Reverse Telecine: This option removes the extra fields added during the telecine
process to convert the film’s 24 fps to NTSC’s 29.97 fps. Selecting this item disables
all other items in the Frame Controls pane. See
About Reverse Telecine for more
information on 3:2 pull-down and using the Reverse Telecine feature.
• Adaptive Details: Select this checkbox to use advanced image analysis to distinguish
between noise and edge areas.
• Anti-alias: Use this slider to set a softness level from 0 to 100. This parameter improves
the quality of conversions when you’re scaling media up. For example, when transcoding
standard definition video to high definition, Anti-alias smooths out jagged edges that
might appear in the image.
