第一次使用cy渲染，視頻畫面出現了异常的不穩定

此為前半部分內容，會在明天放出後續內容，這是因為沒有會員限制了視頻的大小

The first time I used Cy rendering, there was abnormal instability in the video frame. This is the first half of the content, and the follow-up content will be released tomorrow because there is no membership limit on the size of the video
