Which medium is known for containing high-capacity video recordings?

The correct answer is DVDs, as they are designed specifically for high-capacity video storage and playback. DVDs can hold significantly more data than earlier mediums, such as VHS tapes and audio cassettes. A standard single-layer DVD can store approximately 4.7 gigabytes of data, which is sufficient for a full-length feature film and often includes additional features like multiple audio tracks and subtitles. This capacity makes DVDs a popular choice for video distribution.

In contrast, microfiche is primarily used for storing images and documents rather than videos. Regular VHS tapes have a lower video quality and capacity compared to DVDs, as they typically store analog signals and can only hold about 2 hours of video on a standard tape. Audio cassettes, on the other hand, are designed for audio recordings and do not support video at all. Hence, when considering the needs of high-capacity video recordings, DVDs stand out clearly as the appropriate medium.
