这里我有一个视频，每隔几秒钟就有一个旋转的动画和视频，在旋转过程中视频变小变大。但是随着时间的推移，时间就乱了。

let degree = 720;
function rotateElement(){
    let spin = `rotate(${degree}deg)`;
    document.getElementById('myVideo').style.transform = spin;
    document.getElementById('myVideo').style.transitionDuration = "1s";
    degree += 720;
}

function smaller(){
    document.getElementById('myVideo').style.maxWidth = "10px";
    document.getElementById('myVideo').style.maxHeight = "10px";
    document.getElementById('myVideo').style.transitionDuration = "1s";
}

function bigger(){
    document.getElementById('myVideo').style.maxWidth = "30vw";
    document.getElementById('myVideo').style.maxHeight = "19vw";
    document.getElementById('myVideo').style.transitionDuration = "1s";
}

//setInterval(change, 5000);



window.onload = function () {
    setInterval(change, 5000);
    setInterval(rotateElement, 4900);
    setInterval(smaller, 4850);
    setInterval(bigger, 5050);
    
};
