What is MP4?
MP4 is the most widely compatible video format in the world. Using efficient H.264 compression, it balances small file sizes with good quality and plays on virtually every device, browser and platform — making it the safe default for sharing video.
What is WAV?
WAV stores uncompressed, CD-quality audio with no loss of fidelity. The files are large, but the perfect quality makes WAV the standard for recording, editing and mastering before exporting to a smaller format.

What WAV gives you: perfect, lossless quality, universally supported by editors and no compression artefacts.
Where MP4 falls short: lossy compression, patent-encumbered codecs and less efficient than newer formats. Converting keeps your content while moving to a format that matches where the file is going.
