About the formats
Video file formats
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.
Video file formats
MPEG (Moving Picture Experts Group)
MP4 (short for MPEG-4 Part 14) files store multimedia - video, audio and subtitles. Websites frequently use them for displaying videos because the MP4 format is universally supported. However, newer video formats, such as WebM, produce smaller file sizes with almost no quality loss. Therefore, you can free up storage by converting your videos to WebM.
