Convert AVI to MP4
AVI dates from 1992, and it shows: enormous files, no web support, and video encodings that modern players refuse to open. Converting to MP4 makes old footage playable on phones, browsers and every current device. The result is H.264 video with AAC audio, the most widely supported pairing there is.
