What is a key feature of the MP4 video format?

• A. Uncompressed video.
• B. Very large file sizes.
• C. Lossless encoding.
• D. Compressed format that allows for small file sizes while maintaining good quality.

Answer: (D)

MP4 is designed to be a compressed format that reduces the amount of data in video and audio streams, producing smaller file sizes while keeping quality high enough for practical viewing. This balance makes MP4 ideal for online streaming and easy storage, unlike uncompressed video which would be very large. While MP4 can carry different types of streams, the common and defining feature is efficient compression that keeps file sizes manageable without sacrificing too much quality.
