Basically, AVI (Audio Video Interleave) and MP4 (MPEG-4 Part 14) are both container formats that are used to store video and audio data.
However, there are some differences between the two formats:
AVI is an older format that was introduced in 1992, and it is supported by a wide range of media players. However, it is not as widely supported as MP4, which is more widely used and supported by a larger number of devices and software.
AVI files tend to be larger in size than MP4 files, as they do not use as efficient a compression method. MP4 files use a more efficient compression algorithm, which results in smaller file sizes for the same quality of the video.
Both AVI and MP4 can provide high-quality video, but MP4 generally offers better quality due to its more efficient compression method.
Overall, MP4 is generally considered a better choice due to its wide compatibility, smaller file size, and better quality. However, if you need to support older devices or software that does not support MP4, AVI may still be a viable option.
