Which technique describes video captured with each frame split into two fields?

• A. Hard sound effect
• B. Key Frame
• C. Layback
• D. Interlaced/Interleaved video

Answer: (D)

Interlaced video describes how the image is captured and displayed when each frame is split into two fields. In this method, one field carries every other line (typically the odd lines) and the other field carries the remaining lines (even lines). These fields are shown in quick sequence to form what looks like a full frame, which helps reduce bandwidth and smooths motion on older displays. This is different from progressive scanning, where every frame is captured and displayed in full at once. Interlacing is common in classic broadcast standards (like NTSC and PAL), though modern systems often deinterlace to produce progressive video.

The other terms refer to different aspects of production: a hard sound effect is an audio element, a key frame is a reference frame for edits or effects in a timeline, and layback is a post-production transfer process, not a capture method.
