What is AVI vs MP4?
AVI (Audio Video Interleave) is one of the oldest video container formats still in use, dating back to the early 1990s. It's simple and widely readable on Windows, but files are typically far larger than a modern MP4 at the same quality, and support on phones, browsers, and streaming platforms is inconsistent. MP4 uses far more efficient modern compression, playing natively on virtually every device while shrinking the file dramatically.
