Videos are everywhere in our lives today, from entertainment to sharing moments online. But not all videos look great—some have annoying interlacing issues on screens. Deinterlacing fixes this, making images clearer. In this guide, we'll explain how to deinterlace from a video and how to use it to improve video quality.

It's important to grasp interlaced video when discussing deinterlacing. Interlacing doubles a video's perceived frame rate without using more bandwidth. Each frame contains two fields captured at different times, one with odd-numbered lines and the other with even-numbered lines. This technique reduces flicker and enhances motion perception, often seen in analog camcorders and VCRs.
However, fast-moving scenes can lead to interlaced videos, noticeable by horizontal stripes on the screen. Deinterlacing fixes this by converting mixed frames into standard video frames, removing interlaced lines.
Modern screens like LCD, DLP, and OLED only handle deinterlaced videos since they have fixed resolutions. In other words, if you want to watch interlaced videos on your computer or smartphone, the two fields have to blend into one smooth frame. This blending is what we call deinterlacing.
Aiseesoft Video Converter Ultimate is a powerful tool for videos. It uses smart technology to improve video quality by removing interlacing lines. You can also edit videos easily with features like cropping and merging. It makes converting videos to different formats a breeze, and you can customize settings like bitrate and resolution. With support for over 1000 formats, it's the best choice for improving video quality without any hassle.
Features
Here's how to deinterlace videos using Video Converter Ultimate:
Step 1. Add Your Videos
First, download and install Video Converter Ultimate on your Windows or Mac computer. Then, open the program and either drag and drop your interlaced videos into the window or use the Add File menu to add them.
Step 2. Deinterlace
Select an interlaced video from the media library. Click the Edit menu at the top to access the Video Editor. In the Effect tab, check the Deinterlacing option at the bottom right corner. Preview the result and click Apply to confirm.
Step 3. Export
Once all videos are processed, head to the bottom of the main interface. From the Profile dropdown menu, choose the desired format or target device. Click Browse to select the destination folder, and adjust any other settings if needed. Finally, hit Convert to export the videos.
VLC Media Player is a well-known media player used worldwide. It's not just for playing videos; it can also edit them. However, like many open-source programs, VLC hides lots of features in its menus, so users often miss out on its full potential, like the Deinterlace tool. This feature helps fix interlaced videos seamlessly.
Here's how to use it:
Step 1. Open the latest version of VLC and import your interlaced video using the Media menu, like Open File.
Step 2. Go to Video -> Deinterlace and turn it "On" to fix your video's display.
Step 3. Enjoy your video as usual. When you're done, return to Video -> Deinterlace and turn it "Off" to disable the feature.
Handbrake is another free option for fixing interlaced videos, especially for Windows users (Mac users can find Handbrake for Mac). Unlike VLC, Handbrake will edit your video and replace the original file. It's a bit tricky to use, though. Here's what to do:
Step 1. Open Handbrake on your computer and add the interlaced video in the Source tab. It's wise to make a copy of your video first to avoid any potential loss.
Step 2. In the Output Settings section, go to the Filters tab. Choose Deinterlace, and pick a method like Custom, Fast, Slow, or Slower, based on your video's condition.
Step 3. Finally, click Start to kick off the process.
In this article, we've discussed how to deinterlace videos, giving you a clear idea of what's involved and how to do it yourself. There are three main methods to smooth out interlaced videos. Aiseesoft Video Converter Ultimate is easy to use and maintains video quality while deinterlacing. VLC Media Player can adjust interlaced video display without changing the original files, but playback might be limited to VLC. Handbrake is another option, and it's free, but it's more technical. Choose the method that works best for you and follow our instructions for the results you want.
