VLC is a powerful media player application welcome by a large number of people around the world. Not only does VLC Player provide great video playback performance, excellent extendibility and high stability, it also offers some other practical functions that make the video you play be smoother and more enjoyable. The deinterlacing function, for example is a practical function in VLC that could enhance your video watching experience. But a lot of people don’t know how to turn it on. So today let’s see how to activate deinterlacing in VLC, as well as other practical ways to deinterlace a video playback.

Part 1: What is Delnterlacing

First thing first in case that if you aren’t quite familiar with what deinterlacing is, deinterlacing is the process of converting interlaced video, such as common analog television signals or 1080i format HDTV signals, into a non-interlaced or progressive form. Interlaced video signals are commonly found in analog television, digital television (HDTV) when in the 1080i format, some DVD titles, and a smaller number of Blu-ray discs.

The interlacing effect was caused due to how the video image was formed in the first place. An interlaced video frame consists of two sub-fields taken in sequence, each sequentially scanned at odd, and then even, lines of the image sensor. Analog television employed this technique because it allowed for less transmission bandwidth and further eliminated the perceived flicker that a similar frame rate would give using progressive scan. CRT-based displays were able to display interlaced video correctly due to their complete analogue nature. Newer displays are inherently digital, in that the display comprises discrete pixels. Consequently, the two fields need to be combined into a single frame, which leads to various visual defects. The deinterlacing process should try to minimize these.

The deinterlacing technology has been researched for decades and employs complex processing algorithms; however, consistent results have been very hard to achieve. But with the fast development of the video playback technology, some media player applications have found a way to deinterlace videos so that the video could look smoother when being played.

Part 2: How to Activate Deinterlace Function in VLC

As a professional video player application, VLC Player provides tons of advanced video setting options for you to improve your watching experience, and of course, it also has the video deinterlace option available for you to set.

The deinterlace function in VLC aims to solve the image twisting or blurring caused by the interlacing effect. It can be turned on or off, and it can also be set to auto which will give the software the choice to turn it on or off. Activating the deinterlace function in VLC is easy, and there is actually more than one way to do it. The hotkey in VLC to activate or deactivate deinterlacing is “D”. If you just press the ‘D’ button on your keyboard when a video is playing, a message will display on the top-right, telling you that the deinterlacing mode has been switched. To switch it again, just press the hotkey for another time.

Besides the hotkey, you can also set the deinterlacing function manually in the settings panel. To do that, just go to the “Simple Preference” settings page, and switch to the “Video” tab. In the “Video” tab, there is a “Video” section which contains a “Deinterlacing” parameter. You can change the value of the parameter by clicking the dropdown box and select from “On”, “Off” or “Automatic”.

In VLC Player, you can also change the deinterlacing mode and make the deinterlacing effect look better on your video. To change the deinterlacing mode in VLC, just click on the “Video” button in the toolbar, and find “Deinterlacing mode” in the dropdown menu. In the submenu, you can choose whatever deinterlacing mode you want and improve the deinterlacing effect.
