the format is Non-NTSC the labels will be Upper First-Field 1 and Lower
First-Field 2.
2 Set the value of the Dominance (upper or lower first).
3 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.
Field Selection
Basic video de-interlacing discards one field for each frame (say field 2) and
uses some form of scanline interpolation to reconstruct the missing lines.
Composite provides you with three choices when you convert interlaced media
to progressive. You can opt to remove fields which outputs the first field of
each frame, merge the fields which outputs a merge of the two fields of each
frame, or change fields to frames which outputs all input fields separately as
a frame (creates clip of twice the duration).
Depending on the parameter settings, the set of output frames will vary as
described in the following table. The actual frame rate of the output is
unchanged from the input. Each input frame consists of 2 fields, numbered
individually as shown in the top part of the table.
A Fields to Frames operation converts 30i into 30p having twice the duration
of the input. If you desire to have 60p output, you may add a Rate Convert
node after the Deinterlace node.
