The Shift Fields Filter In Final Cut Pro 5
If you were to add an HDV 1080i60 clip with upper-field dominance to a DV NTSC sequence with lower-field dominance, the clip would stutter and appear jerky during playback on an NTSC or PAL video monitor. The stuttering would be due to the fields in the 1080i60 clip playing in the wrong order but, when you add clips into a sequence, Final Cut Pro usually takes care of this problem for you with Automatic Field Dominance Correction.
If you should ever have to do this manually, the Shift Fields Filter's Direction Control will allow you to do so:
- If you need to match a clip with upper-field dominance to a sequence with lower field dominance, you would set the Direction Control to + 1
- To match a clip with lower-filed dominance to a sequence with upper-field dominance, the Direction Control should be set to -1.
The Shift Fields Filter is not necessary when editing clips and sequences with matching field dominance.
