Editing can meet the needs. Video can be audio and video.
I need to correct you. Dubbing movies or something is not using software to eliminate human voices. Instead, only the video image is kept, and the soundtrack and sound effects in the movie must be re-made into audio tracks, which are consistent with the video. This project is huge and needs certain technology.

Generally speaking, dubbing is not an easy task. It's even harder to dub the video. But as long as you love dubbing, it is ok to learn it slowly. I hope you got something.
