![封面图](https://www.mhcf.net/content/uploadfile/202008/df7e1597138254.jpg) 由于参加2020 年伊犁州直教师信息技术与学科教学融合课程培训的缘故,恰好作业是交一个微课视频,时间大约在3到8分钟,于是我便做了一个五分钟左右的视频。 因为电脑散热还没好,所以剪辑视频是完全不可能了。电脑只装了Office 365,于是采用PowerPoint来完成我这个工作,那么现在,便把我这个方法,分享给您。 很简单。 首先,你要有一个五分钟所有的微课教案。 其次,你要做好一个五分钟所有微课的课件。 然后,我们便开始。 * * * 根据自己在每一张课件决定讲的内容,准备好你的讲话录音。将你的声音录好,并以mp3的格式准备好。 ![001](https://www.mhcf.net/content/uploadfile/202008/03d01597138252.png) 如图所示,完全准备好后,咱们就可以开始了。 使用PPT打开你的课件。我采用的是Office 365,后面的操作也基于这个,**不是金山WPS**。而且,也不可能是**WPS**软件。 点击**插入**,找到**音频**,插入你的音频。 ![002](https://www.mhcf.net/content/uploadfile/202008/03d01598592055.png) 这个时候屏幕上会出现一个小喇叭,选中它,把它移动到PPT显示内容的外面。 ![003](https://www.mhcf.net/content/uploadfile/202008/b01c1598592055.png) 如图所示,把它放在播放时看不到的地方,这样就不影响我们后续了。 紧接着,点击**动画**,选择**动画窗格**,你就会在右边发现一个三角播放箭头和一个**1**,这个**1**就是我们前面的第一页音频**1.mp3**。 ![004](https://www.mhcf.net/content/uploadfile/202008/b07f1598592055.png) 插入就完了吗?当然没有。 选中**→1**,然后右键打开**效果选项**,紧接着选择**计时**,在**开始**里选择**与上一动画同时**。 ![005](https://www.mhcf.net/content/uploadfile/202008/20ae1597138253.png) 完成后,把这个音频播放放在所有效果的第一个。 ![006](https://www.mhcf.net/content/uploadfile/202008/18391597138253.png) 完成了后,按Shitf+F5,便会从这一页开始播放,你可以体验一下当这一页PPT开始的时候,你的声音也如约而来的感觉。 将每一页都如此操作后,我们就要考虑让它自动播放了。 点击**切换**,再勾选**设置自动换片时间**。也许你会说,都是00:00.00,需要管吗? ![007](https://www.mhcf.net/content/uploadfile/202008/e8821597138253.png) 答案是并不是很需要。因为会在播放完所有的效果后才会到下一页。 当你所有都完成后,按**F5**,从头播放,如果成功从第一页到最后一页都是这样,那么恭喜你,完成了。 我想为所有的声音来一个背景音乐怎么办? 我需要是的视频格式文件怎么办? ![008](https://www.mhcf.net/content/uploadfile/202008/17c71597138254.png) 在第一张PPT页面之前插入一个页面,然后把你的背景音乐添加进去,在动画效果里,选择在第99张之后停止播放。同时,在选择**计时**,在**开始**里选择**与上一动画同时**。 同时,在切换里,设置为自动切换。 这样,一开始这一张会一闪而过。那么怎么美化下呢?用一张黑色的方框盖住。 做完这这些,请按Ctrl+S,保存一下。否则东西没了可能想哭。 现在,我们就最后一个任务:把演示文稿变成视频文件。 点击**文件**,选择**另存为**,然后在类型里选择**MPEG-4视频**,也就是.mp4格式,完成后按一下保存。 ![009](https://www.mhcf.net/content/uploadfile/202008/d2731597138254.png) 你会发现电脑不会动了。 没事,请准备一杯咖啡,打开**梦幻辰风**,看看姜老师写过的一些乱七八糟的文字。 在一段时间后,你就发现你的视频,好了。 在完成后,你就可以将视频上传了。PowerPoint导出的视频清晰度很高,视频很大。因此,你可以用格式工厂等软件,把视频压缩一下。 好了,祝你,录好你的微课。
