What is AVI Video File Format?
The AVI video file format, which stands for Audio Video Interleave, is a multimedia container format developed by Microsoft in the early 1990s.

Initially, AVI files were limited to 32-bit color depth and could only support a maximum frame rate of 30 frames per second. However, over the years, the format has evolved to support a wide range of video and audio codecs, resulting in better quality and compatibility.
