What Quality Will the MP3 Be?
The MP3 can only be as good as the video's audio track. Most MP4 videos carry AAC audio at roughly 128–256kbps, so extracting to a 320kbps MP3 preserves that audio without adding much further loss — it doesn't invent quality the video never had. Choose 320 kbps to keep the result as clean as the source. Converting many other video types? Use Video to MP3.
