Why convert AVI to MP4?
AVI is a 30-year-old container with outdated codecs that produce huge files by modern standards. Converting AVI to MP4 with H.264 typically shrinks the file several-fold while looking identical.
MP4 also streams progressively on the web, so converted videos start playing instantly instead of downloading fully first.
