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 file formats
M4A files store audio using the AAC codec. M4A stands for MPEG-4 Audio. It is very similar to MP4 with the difference being the lack of a video/subtitle track in the file.
