The first method: you find the music in this video for backup, and then use the Windows Movie Maker that comes with the system to process it, eliminate the original sound, match the found backup music, or simply find a new music you like. The software of Windows Movie Maker is simple, helpful and easy to use. Basically, everyone brings their own. When dealing with audio, remember to expand the+sign after "video". If you have any questions, you can leave a message on my Baidu space and continue to reply.
