The difference between media files and encoding: A file is a collection that includes both video and audio, and even scripts. It can also be called a container; the compression algorithm of the video and audio in the file is the specific encoding. In other words, in an .avi file, the video may be encoded a or encoded b, and the audio may be encoded 5 or 6. Therefore, Qianqianjingting can only convert some of the specific audio encodings.
I have answered some questions about video background music extraction before. Usually, I use Qianqianjingting to convert directly, which is convenient, but sometimes it doesn't work: it is also a flv file, and it is wrong to convert it with GoldWave, so I can only use special software to convert it.
Right-click the song in the playlist---convert format---select MP3 as the output format, and then click Configuration on the right. Generally, an MP3 song of about 4M has a bit rate of 128. Just adjust the bit rate to 64 or 32. If the bit rate is too low, the sound quality of the song will deteriorate, but the bit rate of 64 is still acceptable.
