Special Processing export settings

When you choose Special Processing from the menu at the top of the Export Movie Settings dialog box, you can click Modify and specify the following options as necessary:

Left, Right, Top, and Bottom Type margin dimensions in pixels or drag the handles on the cropping rectangle to crop the exported video. The Size readout indicates the pixel dimensions of the frame after cropping. If you specified Cinepak compression, make sure that the final dimensions are divisible by 4, because Cinepak works most efficiently with 4x4 pixel cells.

Scale to (frame size) Select 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.

Slider under the Preview Drag to preview how the current Special Processing options affect other frames.

Noise Reduction Select 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.

Better Resize Select 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.

Deinterlace Select 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.

Gamma Select to specify a value by dragging the slider. Gamma adjusts midtones while preserving the lightest and darkest parts of the picture. This option helps 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.

Reset Click if you want to revert to the settings that were in use before you opened the Special Processing dialog box.
