Part 1. AVI vs. MP4 - Definition
AVI (short for Audio Video Interleave) and MP4 (short for MPEG-4 or MPEG-4 Part 14) are two popular digital video file formats used to store and play multimedia content such as video and audio. Both of them serve the same basic purpose – delivering video and audio together. AVI is good for quality yet older, while MP4 is modern and more widely supported.
AVI is a proprietary multimedia container format developed by Microsoft in 1992. It supports multiple audio and video streams, storing video and audio data together in a file. However, as AVI is developed by Windows, it goes well with Windows devices. Still, it may require extra codecs on other platforms. Moreover, it supports so many different codecs that it often results in larger file sizes compared to newer formats like MP4.
MP4 is a digital multimedia container format developed by the Moving Picture Experts Group in 2001. It stores video, audio, and other data like subtitles and images in one file. MP4 uses codecs like H.264 or H.265, which makes files smaller while still maintaining good quality (but not as high quality as AVI). Whether you are going to watch or store videos on cell phones, computers or streaming platforms, MP4 is a good choice for you. Moreover, it takes up less storage space than AVI.
