On the De-interlacing tab you can set how and when to convert interlaced video into a non-interlaced form.

De-interlace settings

•Select None if you don't wish to use de-interlacing.

•Select Perform de-interlacing if you want to use de-interlacing, and then select When to apply de-interlacing from the drop-down.

•If using hardware acceleration during playback, select the de-interlacing algorithm from the second drop-down list. Try each option to see which  provides you with the best results.

•If using software decoding during playback, select the de-interlacing algorithm from the third drop-down list. Try each option to see which provides you with the best results.

On the Miscellaneous tab you can control how 4:3 video is converted to 16:9 (and vice versa).

Aspect ratio preference

•Always maintain video aspect ratio: select this option to retain the original aspect ratio whenever you resize the video display. This option is mutually exclusive with the TrueTheater Stretch option below.

•Apply stretch: select this option to stretch all parts of the video equally, resulting in noticeable distortion when the aspect ratio of the video display does not match the aspect ratio of the monitor.

•Crop to fill: when watching 2:35:1 Blu-ray movies on an ultra wide 21:9 monitor, use this option to crop out the black areas on all four sides of the video for a better fit. Crop to fill can also be used on standard 16:9 monitors to zoom in on the video.

TrueTheater Stretch

TrueTheater Stretch* is a non-linear video stretching technology that produces minimal distortion in the center of the picture. TrueTheater Stretch feature is only available in full screen mode and is for DVD titles with a widescreen aspect ratio (i.e. optimal with 16:9 on a 4:3 monitor). It employs CyberLink's unique Pano Vision video technology to stretch the movie to fit the monitor size.

Once enabled, select one of the following options:

•Smart Stretch: (recommended for most videos) crops and stretches the sides of the picture slightly, while keeping the center as is.

•Fit to Screen: keeps the center of the picture as is, while stretching the sides slightly.

•Smart for 2.35:1: for disc titles that have an aspect ratio of 2.35:1. This setting is specifically designed to maximize the display space of widescreen (16:9 or 16:10) display devices when viewing discs with this aspect ratio.

High performance mode

•Enable high performance mode for UHD videos and displays: select this option to enable a high performance mode. When playing video files on displays larger than Quad HD+ (or any file greater than 3300 X 1900 resolution), CyberLink PowerDVD enters a high performance mode that disables the following non-essential playback features:

•Video rotation.

•Video Scene Selector (Video mark in/out).

•Instant Preview.

•Instant Zoom (Zoom in/out).

•Dual subtitle display.

•Subtitle customization for font, color, and size.
