Which of the following best describes 'compression' in video?

Compression in video refers to a technique that reduces the file size of video content while striving to maintain its quality. This process is essential in the digital age, as video files can be very large and unwieldy for storage and transmission. By employing various algorithms and encoding formats, compression allows for more efficient storage and faster streaming without significantly degrading the viewing experience.

For example, video codecs like H.264 or H.265 utilize compression methods that remove redundant data and reduce the bitrate, allowing videos to take up less space on devices and load more quickly when streamed online. This balance between file size and quality is what makes compression a crucial aspect of modern video technologies, enabling smoother playback and more accessible sharing of content across networks and devices.

Other options, while they mention aspects of video processing, do not accurately capture the essence of compression as it relates specifically to size reduction and quality preservation.
