AVI and MP4 are both multimedia container format that is widely used. AVI format works on the DivX codec that is known for its compression while maintaining high quality. MP4, on the other hand, is based MPEG4 AVC/H.264 codec that offers lossy compression. Thus if you talk in terms of quality AVI is definitely better as compared to MP4 format.

AVI format is majorly used by media players that are Windows-based and uses the supported codec. Being large in size AVI format is not a good choice for portable devices and streaming. MP4 being smaller in size can be easily accessed by all types of players and devices and is also ideal for web posting and streaming.

Thus it can be concluded that MP4 is a better choice of video format for sharing, storing, and other purposes if a little bit of quality can be compromised.
