Part 2. H.264 VS AVI

What is H.264?

Shortly, H.264 is a codec standard for Blu-Ray discs. It is also known as a standard for video compression, and the main purpose for this standard is to provide the public with high-definition videos. This standard format is very often used for online video streaming and thus used by websites like YouTube and Vimeo, and also used for broadcasting purposes (cable TV, satellite, etc). One of the slightly negative sides of H.264 is that it can be heavy on the disk space and it requires a better hardware.

What is AVI?

On the other hand there is AVI formats (Audio Video Interleave) which is a container format produced by Microsoft. AVI files provide synchronised audio and video playback. It supports multiple streaming channels. The AVI format is also supported by older hardware systems and plays smoothly on newer or older computers. It is important to know that AVI doesn't support compression as is the case with h264, thus it doesn't access any future chunk of information in its container package (which may lead to significant lagging if the hardware is older).
