Separating fields in interlaced video (6.5)

Separating fields is critical if you plan to make significant changes to interlace footage. By separating fields, After Effects accurately converts the two interlaced frames in the video to noninterlaced frames, while preserving the maximum amount of image quality. After Effects 6.5 improves the resulting image quality in field-separated footage and has renamed the Motion Detect (Best Quality Only) option to Preserve Edges (Best Quality Only) in the Interpret Footage dialog box. (For more information, see "Using interlaced video in After Effects" on page 72.)
