Seek the background music and video of Tai Chi Chuan.

Clouds and water spray gods are both good choices. I prefer the Heart Sutra, which has no ups and downs and is easy to cut and merge. Audition can enter hi.baidu.com/panying to find music with a fixed duration. Others, such as moonlight on the spring river and fishing boats singing late, are also people's favorite music.

2, video special effects I suggest you do your own video content, because no matter how good other people's things are, they are not as targeted as your own. I wonder what software you used to make the Tai Ji Chuan video? In audio-visual software, you can easily make transitions, special effects, subtitle animation, picture-in-picture and so on.
