更刚庆夜呢今认改视频分辨率的方法：
1、第一步：首先需要下载一个qq影音，用QQ影音打开需要更改分辨率大小的视频，按下暂停。

2、第二步：右却严信热令键点击选择菜单【转码/截取/合并】，再一级菜单选择【视频/音频截取】。

3、第三步：拖动截取进度条的位置，一般情哪稳况下是拉两端终点，表示截取整个视频，或者说对整个视频进行处理。

4、第四步：默认截取后无损保存视频，这也等于没有改变视频的分辨率，此时需要点击下面的选项【保存视频】，这里有更多的设置。

5、第五步：首先点击勾选【保持纵横比】，也就是保持原来视频的比例，然后手动输入视频需要更改的分辨率大小，勾选【保持纵横比】之后会自动计算长和宽另外一个数值。

6、第六步：视频默认保存格式为MP4，也可以根据需要选择其他保存格式。

7、第七步：点击确定后，视频开始转换，由于视频更改大小需要重新运算，所以会花比较长的时间，耐心等待转换成功即可。
