Which of the following video file types is typically used for high-definition video?

MP4, or MPEG-4 Part 14, is widely considered a standard format for high-definition video. This format is favored for its balance between high-quality video and relatively low file size, which makes it suitable for streaming and playback across various devices. Its compatibility with most video players and online platforms enhances its popularity, particularly for HD content.

MP4 supports advanced encoding technologies such as H.264, which allows for efficient compression of high-definition video while maintaining quality. This encoding is essential for delivering HD content effectively, whether in online streaming, mobile devices, or media players. Hence, MP4 is often the go-to choice for both content creators and consumers seeking high-definition video experiences.

The other formats do have their uses, but they may not provide the same level of efficiency and compatibility when it comes to HD video distribution.
