Multiple Choice

Which file format is commonly used for video?

Explanation:
Most video content today uses mp4 because it combines efficient compression with broad compatibility across devices and platforms. The mp4 container typically carries common codecs like H.264 for video and AAC for audio, which deliver good quality at smaller file sizes and support streaming and progressive download. This universal support makes mp4 the default choice for web video, mobile apps, and many media players. Other formats have their niche—MOV is closely tied to Apple workflows, AVI is older and less suited to modern streaming, and MKV is feature-rich but not as universally supported by hardware and browsers.
