S_FieldRemove Adaptively removes video field interlacing artifacts from areas with motion, without blurring the stationary parts of the image. A 'Motion Matte' is generated internally and the moving areas are deinterlaced with the usual loss of vertical resolution, but the stationary areas are not deinterlaced and should remain sharp. In the Sapphire Time effects submenu. Inputs: Source:  The clip to be processed.

Parameters:

Mode:   Popup menu,  Default: Same Speed.
Selects speed-change options.

Same Speed:  No change in speed.

NTSC to Film:  Converts 60 field/sec input to 24 frame/sec output. Every 5 frames of input are converted to 4 frames of output, so in this mode only 4/5 of your output clip will be useful.

Half Speed:  Every field of input is converted to one frame of output. In this mode, you should normally first pad your input clip to make it twice as long, so the correct number of output frames will be generated.

Scale Mo Matte:   Default: 4,  Range: 0 or greater.
Increase to remove more field artifacts, or decrease to remove fewer and keep the image sharper.

Threshold Matte:   Default: 0.05,  Range: 0 or greater.
This value is subtracted from the Motion Matte and can be increased to reduce unwanted deinterlacing due just to noise.

Blur Mo Matte:   Default: 0.028,  Range: 0 or greater.
Determines how much the Motion Matte is smoothed out to avoid sharp transitions between the interlaced and deinterlaced areas.

Show:   Popup menu,  Default: Result.
Selects the output option.

Result:  output the deinterlaced result normally.

MotionMatte:  this allows viewing the Motion Matte itself, and can be helpful when adjusting the other parameters above.

Use Field:   Popup menu,  Default: Lower.
Selects which field to preserve in areas with field artifacts. This parameter only has an affect when using Same Speed mode.

Lower:  keeps the lower field.

Upper:  keeps the upper field.

Merge:  Uses the average of both fields.

Field Dominance:   Popup menu,  Default: Lower First.
Selects the ordering of the output fields. This parameter only has an affect when NOT using Same Speed mode.

Lower First:  The lower field is first in time.

Upper First:  The upper field is first in time.
