026_视频/合成的时间轴/进度条制作

小白球的运动为时间进度标记

当前表达式为：

start = thisComp.layer("Video").inPoint;

end = thisComp.layer("Video").outPoint;

x = time/(end-start)*thisComp.width;

[x,value[1]];

thisComp.width

分隔栏的位置设定:thisComp.layer(video").marker.key(1).time.

V1标记点的位置

Before

After

完整表达式如下：

start = thisComp.layer("Video").inPoint;

end = thisComp.layer("Video").outPoint;

x = thisComp.layer("Video").marker.key(1).time/(end-start)*thisComp.width;

[x,value[1]];

x1 = thisComp.layer("01").transform.position[0];

x2 = thisComp.layer("02").transform.position[0];

x = (x1+x2)/2;

[x,value[1]]

最终演示效果

thisComp.layer("Video").marker.key(1).comment
