Interlacing Clips
Interlace clips to combine de-interlaced fields into interlaced frames. The resulting clip is half as long as the
original.
To interlace clips:
1 Select Tools, and select the Clip tab.
2 Click Interlace.
3 From the Interlace Parameter box, select Field 1 or Field 2 to establish the resulting clip's field dominance.
4 Select the clip to interlace.
5 Select the destination.
The resulting clip appears, now with half the duration.
Merging Fields
Merging fields blends pixels in neighbouring field lines to reduce artifacts caused by motion jitter. Merge
fields when there is interlaced material to be output to a progressive scan format.
To merge fields:
1 Select Tools, and select the Clip tab.
2 Click Field Merge.
3 Set the percentage of blending between fields in the Level field.
ResultValue
The average pixel value is replicated to both fields in an F1/F2 merge-pair, resulting in
total field merging.
100%
Pixels on each line in an F1/F2 merge-pair are replaced by pixels defined by 50% of
their original value and 50% of the blend, or field merge result.
50%
No change is applied to the clip.0%
4 Select the clip to process.
5 Select the destination.
The field dominance of the clip is reversed.
Changing the Scan Mode of a Project
The project scan mode dictates how interlaced video formats are captured from tape, sent to the broadcast
monitor in-session, and output to tape. The project scan mode also determines field-based processing.
You can change the scan mode of your project by selecting an alternative scan mode option. Do this, for
example, to view a PAL clip in an NTSC project properly before reversing its field dominance. Generally,
changing the scan mode of a project is a temporary measure performed only to allow for the monitoring of
clips whose format does not match the scan mode of the current project.
