Field Selector

Field Selector is a freeware filter for Final Cut Express and Final Cut Pro that displays only one field of each video frame. You can select which field to display; the other field, that is not selected, may be made transparent to show clips in the tracks below.

It allows to analyze each field separately, for example to check the comb effect or to control the field sequence in a movie, or also to modify each field separately in a frame.

Warning: Field Selector does not swap nor slip fields, and it does not de-interlace video: it simply shows or hides each single field.
