About the formats

Extension mp4
Category Video file formats
Developed by MPEG (Moving Picture Experts Group)
Mime type video/mp4

Description

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.
Extension flac
Category Audio/Music file formats
Developed by Xiph.Org Foundation
Mime type audio/flac

Description

FLAC, or Free Lossless Audio Codec, files contain digital audio. FLAC files utilize lossless quality, meaning that there is no loss of any original sound data. When compared to MP3 (lossy audio format), FLAC files are generally larger. Nonetheless, FLAC’s lossless compression algorithm can reduce audio by up to 70%, and still be able to reproduce the original audio afterwards. The format is royalty-free.
