How to Deinterlace Your Video Without Losing Quality

This guide shares four ways to deinterlace video on your desktop or online without quality loss. Old videos that use outdated interlaced scanning look good on a traditional TV. However, they will become blurry when flickering on modern monitors and mobile devices. The good news is that you can fix this problem and elevate video quality with the right tool. Let's learn the proven methods and concrete steps.

Part 1: What Is a Deinterlacing Video

To define what deinterlacing video is, we need to understand interlacing first. It is an old visual technology. Instead of drawing a complete image, it splits each frame into two fields. The first field contains the odd-numbered lines and the second field contains the even-numbered lines. The two fields are shown in rapid alternation. If the speed is high enough, your eye blends them into what appears to be a single frame. An interlacing video looks smooth on traditional TV. However, it becomes blurry and shaking on modern displays.

Video deinterlacing is the process of converting interlaced video into progressive-scan video. A progressive video displays each frame in full image, providing clean motion on modern displays.
