Explanation:
Detailed explanation-1: -Technically, an MP4 is a digital container file, which means it contains compressed video data and other associated data necessary for playing the video, but the MP4 is only a wrapper around the video, not the video itself. MP4 files are typically more compressed and thus smaller than other video file types.
Detailed explanation-2: -MP3. MP3 (MPEG-1 Audio Layer III) is the most popular of the lossy formats. AAC. Advanced Audio Coding or AAC files (also known as MPEG-4 AAC), take up very little space and are good for streaming, especially over mobile devices. Ogg Vorbis. FLAC. ALAC. WAV. AIFF. DSD. More items
