Question

利用格式工厂将视频转换后为什么速度变得很快了?

Answer 1

因为你转换每秒帧速率调整的过快，转换所以才会使得视频速度变快。
想要视频进行正常播放的快，可以这样转换：
1、打开电脑界面，找到要转换的视频。
/iknow-pic.cdn.bcebos.com/55e736d12f2eb938cc7c52cada628535e5dd6ff0"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/55e736d12f2eb938cc7c52cada628535e5dd6ff0?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/55e736d12f2eb938cc7c52cada628535e5dd6ff0"/>
2、在视频上面右键单击，在出现的菜单中选择“属性”选项。

3、在弹出的对话框中，点击“详细信息”选项，然后看到这个视频的帧速率为25帧/秒。

4、双击桌面上面的“格式工厂”图标。

9、在弹出的对话框中，在每秒桢数的后面选择“25”

Answer 2

一、你的视频是什么格式的?
如果是MOV格式，则需要安装QT播放器。
二、你输出的帧速率，不能默认，原视频是多少，就选多少。
转换后速度变快的原因，就是帧速率参数设置不对引起的!!!!-----
也请楼上的朋友们，注意这一点!!这才是根本原因所在。
如果有其它问题，可以追问。
