Which of the following refers to a technology that enables the compression and decompression of digital video?

The correct answer is a video codec, which is a crucial technology in the realm of digital video processing. A video codec serves the function of compressing video files for storage and transmission, which conserves bandwidth and reduces file size. Once the video is needed for playback or editing, the codec can decompress it, enabling smooth playback or further manipulation.

This process is vital for managing the vast amounts of data associated with high-quality video, allowing filmmakers and content creators to deliver optimal video experiences across various platforms and devices without overwhelming system resources. Different codecs have distinct characteristics, such as varying levels of compression efficiency and support for different formats, thus influencing video quality and performance.

While video editors, media players, and streaming services are relevant components in the workflow of video production and consumption, they do not perform the specific function of compressing and decompressing video data directly. Video editors work with video codecs but are primarily tools for editing content, media players facilitate viewing of videos, and streaming services focus on delivering content over the internet.
