Let me say two sentences, let me say two sentences. There are various ways to make videos, and most of the collected videos are finished by secondary editing. First of all, video recording, downloading music, making mask lyrics and synthesizing them with software.

For example, AE software is used to make the opening credits, silly girl software is used to make the mask lyrics, and audio and video are used for synthesis. The audio and video functions are very powerful, and what I said is not necessarily correct.
