MP4 is a widely supported container for video and audio. Compatibility and file size depend on the codecs and settings used inside it, which is why MP4 with H.264 video and AAC audio is a common choice for sharing and uploading.
MP4 is widely supported by browsers, phones, smart TVs and desktop players. Playback still depends on the video and audio codecs stored inside the file.
WAV is an audio container that commonly stores uncompressed PCM sound. PCM keeps the encoded samples without lossy compression, which is useful for editing and mastering but usually creates much larger files than MP3 or AAC.
WAV is supported by common media players and audio editors, including Windows Media Player, QuickTime and VLC. Support can depend on the codec stored inside the file.
