How to Activate (or Deactivate) Deinterlacing in VLC Media Player

Deinterlacing is a solution to display interlaced videos on progressive screens. It is not the perfect solution as there might be combing in the image but we will talk about that in a little while. This post is dedicated to provide information to turn on (auto) or off the ‘deinterlace’ feature in VLC media player. It is just activated or deactivated with a press of a button.

The hotkey or shortcut key in VLC to activate or deactivate deinterlacing: D

Just press the ‘D’ button on your keyboard when a video is playing and a message will display on the top-right.

Deinterlace on (Auto) – When it is activated.

Deinterlace off – When it is turned off.

It is as simple as that.

What is deinterlacing?

Videos are of two types: Interlaced and progressive. Interlaced videos are those where one frame will only have alternate lines of a picture displayed. Progressive videos sequentially draw all the lines that a video has. Interlaced videos (eg. 1080i videos) are used by cable companies to save bandwidth while broadcasting. Progressive videos (eg. 1080p videos) are common with streaming sites like Netflix.

The displays that we have these days are all progressive. Meaning, they support 1080p, 720p videos by default and not 1080i. The solution to display such interlaced videos on our progressive screen is to deinterlace them. Now, it’s not perfect as the science behind deinterlacing cannot solve all the problems and people might notice a slight combing in parts of an image. But it is the only solution we have and it works for most.
