AVI, short for Audio Video Interleaved, is one of the oldest media formats which was introduced to the public by Microsoft in 1992. Since then, it has become so popular that many people consider it the standard for storing audio and video data on computers. AVI file format works by combining audio and video into a single file (in a container) which enables it to support simultaneous media playback.
Data stored in AVI files (audio and video) can be compressed in various codecs, some common ones being MPEG-2, DivX, or XviD. For this reason, AVI files may look similar on the outside but are entirely different from each other on the inside in terms of the codec used. Additionally, they can also contain data that is not compressed by any codec.
AVI files use less compression than similar media formats such as .mp4 and .mov.
If you’re looking to edit a .avi file, then you’ll need to install a specific video editing program on your computer. Some examples include Shotcut and Filmora Video Editor. Once you have these applications, you can easily edit your AVI files.
