In Premiere there is an "interlace consecutive frames" option in the field render settings which is useful for resolving field judder problems in certain downloaded mpeg files. Unfortunately I need to use these files within an AEX composition and I can't find an equivalent field setting in AEX anywhere. Can anyone help?
It doesn't exist. You will have to use plug-ins like RevisionFX' FieldsKit or mimic it by manually combining compositions with doubled framerates, and possibly tricks like using Venetian Blinds to create the interlace pattern.
