I am very happy to answer your question. If you use mobile phone, first download a clip, click the + sign in the middle, and start creating.
Import the video you need to make and start editing when needed. For the dubbing section, click "Clip - Split", then click the button next to Split, click on the segment that needs to be dubbed, select the volume, turn it to the lowest, then click on Music, select the music you like, and just use it, so that the previous paragraph It's the original sound, followed by dubbing. If you need multiple dubbing segments, just split it several times and just follow the steps above.
Mobile phone editing is relatively simple and is a fool-like operation. Computer operation is more complicated. There are also sound effects and dubbing in the clips and funny dubbing in short videos. You can refer to it. I'll post pictures of the steps for you.
