flv怎么转换成mp4格式？

我比较推荐微商视频助手这款软件，它里面就有格式转换的功能。用它来将flv格式转换成mp4格式是很简单的，只需将文件添加上去∞再选择转换的格式，就可以成功转换了。

1、首先将已经下载好的FLV格式的文件上传到电脑里。最好放在根目录里，为的是方便路径输入。

2、同时按住win键和R键，打开运行对话框，并在里面输入cmd，点击确定

3、接着会弹出命令输入窗口，直接在上面输入F:然后回车，注意这里的“:”输入时要关闭中文输入法，否则系统无法识别。

4、回车后接着下一行的光标输入copy/b/（目标flv视频）.flvV01.mp4,下图是一个例子

5、当命令输入窗口中出现“已复制”时，表示已经转换成功，并且已经保存到原视频的目录里了。

6、以上是不借助视频转换软件完成的操作，如果转换之后出现错误，可以从网上下载视频转换工具进行转换。
