What is an MP4 file?
MP4, which stands for MPEG-4 Part 14, is a versatile digital multimedia container format most commonly used to store video and audio. Developed in 2001 by the Moving Picture Experts Group (MPEG), it's based on the earlier QuickTime File Format (QTFF) but with additional support for newer features and codecs. The key advantage of MP4 is its flexibility—it can contain video (usually encoded with H.264/AVC or H.265/HEVC), audio (like AAC or MP3), subtitles, and still images, all in a single file. Its widespread adoption is due to its excellent compression efficiency, which provides high-quality video in relatively small file sizes, making it ideal for everything from streaming services and video conferencing to digital downloads and mobile devices. Because it's so widely supported, you can play MP4 files on almost any device or platform without needing special software.
What is an AIFF file?
AIFF (Audio Interchange File Format) is an audio file format used for storing digital audio data. It was developed by Apple in 1988 and is widely used for professional audio applications. AIFF files are uncompressed, which means they retain the original audio quality without any loss of data. This makes them ideal for use in music production and other professional audio applications where audio quality is of the utmost importance. AIFF files are not as widely supported as MP3 files, but they are still a popular choice for professional audio applications.
