Smoothing video images Because video images contain two interlaced pictures, you can some- times see a slight banding effect in images acquired from video- recording devices. You can correct this by using the De-Interlace fil- ter and then applying the Unsharp Mask filter. De-Interlace works with all image modes except Black & White. To smooth video images 1 Select one or more paint objects to adjust. You can select an area in one image to de-interlace the selected area only. 2 Choose Image > Filter > Video > De-Interlace. 3 Click Odd fields or Even fields to select bands to eliminate. 4 Choose a replacement method for the eliminated pixels: •   Click Duplication to fill the area by inserting a copy of an adjacent band. •   Click Interpolation to fill the area by inserting intermediate color values based on the color values of neighboring pix- els. This option creates a smoother, more accurate fill than Duplication. 5 After entering the settings you want, click OK.
