What is the benefit of deinterlacing the video in a video encoder?

Deinterlacing in video encoding is used to eliminate the artifacts that occur when the two fields of an interlaced video frame capture different moments in time. These artifacts, known as tearing effects, can be particularly noticeable when there is motion in the scene. Deinterlacing processes the fields to produce a single frame, resulting in a smoother image with reduced tearing. [Reference: Axis Communications - Video Processing Techniques]
