What is MP4?
MP4, or MPEG-4 Part 14, is a widely used digital multimedia container format designed to store video, audio, subtitles, and still images. It supports high-quality video compression using codecs like H.264 or H.265 and audio formats such as AAC or MP3. MP4 files are compatible with nearly all devices and platforms, including smartphones, computers, web browsers, and media players, making it one of the most versatile and accessible video formats available. Unlike M4V, MP4 typically does not include DRM protection, allowing for broader sharing and playback flexibility.
What is AVI?
AVI (Audio Video Interleave) is a multimedia container format developed by Microsoft in 1992 as part of its Video for Windows technology. It stores both video and audio data in a single file, allowing synchronous playback. AVI supports a wide range of codecs for video and audio compression, but it is less efficient than modern formats like MP4 in terms of file size and streaming capabilities. While AVI offers good quality, it often results in larger file sizes due to minimal compression. It is best suited for local playback and editing, especially on Windows systems. However, compatibility with non-Windows platforms may require additional software or conversion.
