视频自己动手 压制RM视频的设置及裁减方法(2)

现在就知道了影片的原始分辨愈为576*324。那到底要裁减多少呢?不要着急,慢慢跟大家
说。MOTO E2的屏是320*240的,也就是4:3。就是说上面的片子裁减后应该是4:3=?:324.这个方程式大家应该都会算吧,324*4=1296,再用1296除3得到裁减后的影片宽度是432。然后用影片的原始宽度576减去裁减后的宽度432=144。144就是我们要裁减掉的宽度。

  上图的左边界、右边界应该填多少呢?我们肯定要左右两边都裁减一样多,这就简单了。拿144除2=72,左边界添72,右边界可不能添72,应该填72+432=504,这样就完成了裁减工作。裁减前后的效果如下图:

用E2看全屏的电影是不是更爽呢?
