What makes MP4 a popular choice for online video sharing?

• A. It is well compressed and supports fast downloading and streaming.
• B. It is uncompressed, preserving maximum quality.
• C. It does not support streaming.
• D. It can only be used on Apple devices.

Answer: (A)

MP4 is popular for online video sharing because it balances quality and file size while working well across devices and browsers. The format uses efficient compression with common codecs like H.264, which keeps video files small enough for quick downloading and smooth streaming without sacrificing too much quality. It’s widely supported across nearly all platforms and players, so a single MP4 file can be played on desktops, phones, tablets, and on popular web browsers, making it ideal for broad sharing. MP4 also supports streaming-friendly features and metadata, subtitles, and multiple tracks, adding versatility for online use. Uncompressed video would create huge files and slow delivery, MP4 does support streaming, and it isn’t limited to Apple devices, so the other options don’t fit.
