Description

AVI is a popular video format, created in the 90’s by Microsoft. It is short for Audio Video Interleave. When compared to other commonly used video formats, such as MOV and MP4, AVI files are usually much larger in size. This is because AVI uses less efficient compression.

To free up space on your device, you can convert AVI videos to more efficient formats like MP4 and WebM.

Description

MKV files are MatrosKa Video files. Like the Russian Matryoshka doll, which contains multiple smaller dolls nested inside each other, the MKV format can contain multiple video, audio, and subtitle tracks inside a single file. This makes it convenient to have one video with a number of audio and subtitle tracks in different languages, all inside a single playable file.
