The
field dominance is whether the top field comes before or after the
bottom field in time. The top field means the field which contains
the highest vertical scanline to be displayed.
To set the field dominance:
- Set the format to either Non-NTSC or
NTSC. If the format is NTSC the dominance will be labeled Upper
First-Field 2 and Lower-First Field 1. If the format is Non-NTSC
the labels will be Upper First-Field 1 and Lower First-Field 2.
- Set the value of the Dominance (upper
or lower first).
- If you do not know the field dominance,
you can press the Guess Dominance button and it will be determined
for you. Keep in mind that this may take several seconds to analyze
frames and may take even longer if the input has a long sequence
of static frames before the action. To stop the analysis, press
the Cancel Guess button.
