Reduce Interlace Flicker effect
The Reduce Interlace Flicker effect reduces high vertical frequencies to make images more suitable for use in an
interlaced medium (such as NTSC video). For example, images with thin horizontal lines can flicker when broadcast.
Reduce Interlace Flicker applies a vertical directional blur to soften horizontal edges to reduce the flickering.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
Note: Flicker may result from fields that haven’t been separated.
