Interlaced Video
Definition
Interlaced Video is a method of encoding video in which each frame is divided into two "fields" — one containing all the odd-numbered horizontal lines of the image, and one containing all the even-numbered lines. The two fields are displayed alternately in rapid succession (at twice the frame rate), creating the illusion of a full frame. Interlaced video was developed for broadcast television to reduce bandwidth while maintaining smooth motion. It has largely been replaced by progressive scan video (in which each frame is captured and displayed as a complete image) in modern production, but interlaced formats (such as 1080i) are still used in some broadcast contexts.
Contextual Usage
The post-production supervisor flags a technical issue: "The broadcast master we received from the client is in 1080i (interlaced), but our delivery specification requires 1080p (progressive). We need to deinterlace the footage before we can deliver it. I'll use the motion-adaptive deinterlacing algorithm in DaVinci Resolve, which should give us the cleanest result."
