Another unwanted effect can arise from inadvertently reversing the
field dominance
, or the order in which the fields
are recorded and displayed. When the field dominance is reversed, motion appears jerky because the fields no longer
appear chronologically. Fields can become reversed in the following situations:
•
The field dominance of the original videotape was the opposite of the field dominance of the video-capture card
used to capture the clip.
•
The field dominance of the original videotape was the opposite of the field dominance of the video-editing or
animation software that last rendered the clip.
•
You have set an interlaced clip to play backward.
You can process fields for an interlaced clip in the sequence so that the clip’s picture and motion quality are preserved
in situations such as changing the clip speed, playing a clip backward, or freezing a video frame.
1
Select a clip in the Timeline panel, and choose Clip > Video Options > Field Options.
2
Select Reverse Field Dominance to change the order in which the clip’s fields appear. This option is useful when
the field dominance of the clip doesn’t match your equipment or when you play a clip backward.

For Processing Options, select one of the following choices:
None
Doesn’t process the clip’s fields.
Interlace Consecutive Frames
Converts pairs of consecutive progressive-scan (noninterlaced) frames into interlaced
fields. This option is useful for converting 60-fps progressive-scan animations into 30-fps interlaced video, because
many animation applications don’t create interlaced frames.
Always Deinterlace
Converts interlaced fields into whole progressive-scan frames. Adobe Premiere Pro deinterlaces
by discarding one field and interpolating a new field based on the lines of the remaining field. It keeps the field
specified in the Field Settings option in the Project Settings.
If you specified No Fields, Adobe Premiere Pro keeps the upper field unless you selected Reverse Field Dominance,
in which case it keeps the lower field. This option is useful when freezing a frame in the clip.
Flicker Removal
Prevents thin horizontal details in an image from flickering by slightly blurring the two fields
together. An object as thin as one scan line flickers because it can appear only in every other field.
