AVI's limitations:
AVI, short for Audio Video Interleave, is a multimedia container format introduced by Microsoft as part of its video for Windows technology. AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback. But the biggest limitation of AVI is its poor compression, so the AVI files are usually much larger. Also while resizing the window of your media player (or on different TVs, especially high-definition ones), the aspect ratios are sometimes lost in translation.

MP4's popularity:
MP4 is also a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital video and digital audio streams, as well as other data such as subtitles and still images. As the movies and videos encoded in MP4 format looks great and with smaller size, now MP4 is commonly used in various multimedia devices like iPad, iPod, iPhone, PSP and other MP4 players now.
