# Deinterlacing

What is deinterlacing? Click here for an explanation.

&kdetv; provides several deinterlacing algorithms that provide different CPU usage and image quality. Two deinterlacing algorithms were ported from &xawtv;, three from &dscaler;. The &dscaler; algorithms are referred in the following as the good (in terms of image quality) deinterlacers.

What do I need to do if I want deinterlacing?

- Use a &video4linux; or &video4linux2; plugin-driven device.

- Configure the &video4linux; device to use &xvideo; display method if you want to use the good deinterlacers.

- Configure the &video4linux; or &video4linux2; plugin to use Full Framerate if you want use one of the good deinterlacers and your CPU is fast enough.

- Choose one of the deinterlacers from the &kdetv; configuration dialog.

- Additionally, you may want to enable the overscan plugin to get rid of image noise at the borders.
