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. Normally, I use Qianqianjing to convert directly, which is convenient, but some problems do not work: it is also a flv file, and it is wrong to convert it with GoldWave, so I can only use special software. Convert.

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.
