AVI on the other hand is designed to hold different video and audio streams for synchronized playback. It is one of the most commonly used formats especially for series and TV Shows, this is because of its high compatibility across all platforms besting even MP4. While some TV won’t be able to play MP4 files, no TV ever rejects AVI. AVI contains lossless video meaning that it can store high-quality video(s) with low size.
