Overview

The Video Deinterlace tool allows you to easily remove interlacing artifacts from your videos, converting interlaced footage into clean, progressive scan video. By supporting advanced filters like YADIF, BWDIF, and W3FDIF, this tool eliminates horizontal comb-like lines from legacy recordings or broadcast feeds, outputting high-quality progressive video in formats like MP4, WebM, MKV, AVI, or MOV while preserving the original audio.

When to Use

  • •When converting legacy DVD rips, analog camcorder footage, or TV broadcasts that display distracting horizontal line artifacts during motion.
  • •When preparing older interlaced video files for modern digital platforms and screens that only support progressive scan.
  • •When you need to choose between standard frame rate output or smoother double-frame rate output using field-based deinterlacing.

How It Works

  • •Upload your interlaced video file in any standard video format.
  • •Select your preferred deinterlacing filter (YADIF, BWDIF, or W3FDIF) and configure the processing mode and field parity.
  • •Choose your desired output format, decide whether to keep the audio track, and process the file to generate the progressive scan video.

Use Cases

Digitizing old family home videos recorded on VHS or DV camcorders to remove interlacing lines.
Preparing broadcast television recordings (often 1080i) for streaming on web platforms that require progressive (1080p) video.
Restoring archival footage for video editing projects where interlacing artifacts degrade visual quality.

Examples

1. Restoring VHS Home Video Transfers

Archivist
Background
An archivist has digitized old VHS tapes, resulting in interlaced MP4 files that show heavy horizontal combing artifacts during fast movements.
Problem
The interlacing lines make the video look low-quality on modern LCD screens.
How to Use
Upload the digitized MP4 file, select the 'BWDIF' filter for high-quality motion handling, set the mode to 'Send Field' for smooth motion, keep the audio enabled, and export as MP4.
Outcome
The output video is converted to a smooth, progressive scan MP4 file with the combing artifacts completely removed.

2. Preparing Broadcast Footage for Web Streaming

Video Editor
Background
A video editor received a 1080i TV broadcast clip that needs to be uploaded to a web platform that only supports progressive video.
Problem
The interlaced video displays jagged edges on moving objects when played back on progressive displays.
How to Use
Upload the broadcast video, choose the 'YADIF' filter, set the Field Parity to 'Auto Detect', select 'Send Frame' mode, choose 'MOV' as the output format, and process the file.
Outcome
A clean, progressive MOV video ready for web upload without any interlacing artifacts.

FAQ

What is the difference between YADIF and BWDIF filters?

YADIF is a widely-used, fast deinterlacing filter, while BWDIF (Bob Weaver Deinterlacing Filter) often provides better detail preservation and fewer artifacts in complex motion scenes.

Should I choose 'Send Frame' or 'Send Field' mode?

'Send Frame' outputs one progressive frame per input frame, while 'Send Field' outputs one progressive frame per input field, resulting in a smoother video with double the frame rate.

What does Field Parity mean?

Field Parity specifies which field is displayed first: Top Field First (TFF) or Bottom Field First (BFF). 'Auto Detect' is recommended for most videos.

Can I keep the original audio in the deinterlaced video?

Yes, checking the 'Keep Audio' option ensures the audio track is preserved and synchronized in the output file.

What output formats are supported?

You can export your deinterlaced video to MP4, WebM, MKV, AVI, or MOV formats.
