About the formats
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.
Audio/Music file formats
Fraunhofer Institute, Nokia, Dolby, AT&T, Sony and others
AAC files are audio files using Advanced Audio Coding compression. AAC is a lossy format, meaning the audio quality remains almost the same as the original source. The slight loss leads to the audio files taking up less space, which makes them ideal for music streaming or when bandwidth is limited. AAC is superior to MP3 for handling frequencies above 16 kHz. The encoding efficiency for transient and stationary signals is also better when compared to MP3.
