If your video was shot with a camera produced before 2005, it may have been recorded in interlaced format. This format can create interlacing artifacts, which appear as many small horizontal lines on the video. These artifacts can be easily removed using the AI filter Deinterlacer.

Here is what the interlacing artifacts look like:

Interlacing artifacts, occur when an interlaced video is displayed on a progressive screen. Since most modern screens are progressive, these artifacts are commonly encountered when viewing older interlaced videos.

The interlaced format was prevalent until the mid-2000s due to its lower bandwidth requirements, making it more cost-effective and easier to broadcast. However, with the rise of faster internet speeds and more affordable digital video, the progressive format gradually replaced the interlaced format.

Modern cameras utilize a progressive scanning format, which eliminates the artifacts often associated with interlaced formats.

Not necessarily. It's possible that a video has already been deinterlaced, meaning it was converted from interlaced to progressive format. In that case, you don't need to apply the Deinterlacer filter.

The best way to determine if a video is interlaced is to play it in your video player and check for interlacing artifacts.

These typically appear as combing or tearing effects when objects move quickly, such as cars or people. Be sure to disable any automatic deinterlacing in your video player settings.

Note: The deinterlace filter may not work correctly if the interlaced video has already been converted to progressive format without proper deinterlacing.
