What changes when you convert MP4 to WAV

  • MP4 video is lossy and WAV audio is lossless: converting cannot restore detail the source already discarded, and the WAV audio file will usually be larger than the original.
  • MP4 video animation cannot be expressed in WAV audio; the first frame is converted as a still image.
  • The video’s audio track is extracted and re-encoded to WAV audio; video frames are discarded.
