There are many common video formats, then why should I convert AVI to MP4?

Before going into the conversion process, let's first discuss why there is a need to convert AVI to MP4.

AVI (Audio Video Interleave) is a multimedia container format built on the RIFF (Resource Interchange File Format). It is Windows standard and was launched by Microsoft. AVI commonly supports video codecs such as XviD and DivX with less compression rate and high-quality media content. Precisely because of the less compression rate, AVI files occupy more storage than MP4. In addition, since AVI is developed by Microsoft, it can't be played on Mac or portable devices.

In contrast, MP4(MPEG-4 Part 14) is a multimedia container format designed for storing metadata such as images, subtitles, videos, audio, etc. MP4 files are usually compressed by H.264, which is the most common codec with the wildest compatibility on almost all devices. The greatest benefit of MP4 is a higher compression rate, which makes the files smaller in size than AVI at the same quality level. Therefore, it's highly recommended to convert AVI to MP4.
