What is deinterlacing? Explanation of the mechanism, output, and release method

When I uploaded the video, horizontal lines appeared and I tried deinterlacing, but the quality of the video deteriorated. Is there a way to deinterlace without degrading the image quality? I am often asked this. What is deinterlacing here? In order to answer this question, I will explain in detail how to deinterlace.

Explaining the meaning of deinterlacing

Deinterlacing is the process of converting interlaced video (video camera footage, DVD-ripped footage, video capture footage), such as a typical analog television signal or a 1080i format HDTV signal, to a non-interlaced format. In English, it is written as deinterlace, and is also called deinterlace. -Quoted from Wikipedia

Generally, there are two types of video formats: one is interlaced video (interlaced scanning method), and the other is progressive video format (sequential scanning method). Deinterlacing refers to converting interlaced video (interlaced scanning method) to progressive video (sequential scanning method). It also refers to the creation of progressive images per second from interlaced images per second.

About the deinterlacing mechanism

After understanding the meaning of deinterlacing, I will introduce the mechanism of deinterlacing. Stripe noise is mainly caused by a combination of “noise specific to the pixels of the sensor” and “regular shifts in the photographed subject.”

The mechanism of deinterlacing (stripe stripe noise removal) is to combine two unfinished images called fields to create one frame of video.
