Part 1: What's Deinterlacing?

Deinterlacing is a process to convert interlaced video sources to progressive scanned videos. Then, you may come across another problem. What's interlaced scanning and progressive scanning?

• Interlaced scanning: It divides a frame video into odd-number and even-number lines of pixels, and takes turns to scan the field formed by odd rows and the field formed by even rows.
• Progressive scanning: It scans each frame from left to right, top to bottom, one by one to display all the pixels.

As a field only contains half of the information of a frame, interleaving scan can save half of the information and maintain the same update rate in the case that the processing speed of the device or the transmission bandwidth cannot process the information of the whole frame in time. Broadcast and television systems, such as NTSC or PAL, usually use interlaced signals instead of progressive signals.

On the other hand, modern devices are fast enough to process and scan entire frames in no time, so they are using progressive scanning. However, if you play interleaving scanning videos on such modern devices, you will get screen scintillation with horizontal lines and half the brightness. That's why you need to deinterlace videos.
