您在使用 Microsoft 的PowerPoint(PowerPoint)应用程序时可能遇到的一些问题可能是音频和视频问题(audio and video problems)。PowerPoint 用户(users)有时报告说，当他们通过电子邮件发送演示文稿时，收件人无法播放演示文稿。它只是拒绝加载。尽管很少遇到此问题，但在某些情况下可能会引起关注。
音频(Audio)和视频(Video)无法在PowerPoint中播放(PowerPoint)
如果您的音频(Audio)和视频(Video)无法在PowerPoint中播放，那么这篇文章将引导您完成对PowerPoint 中的音频和视频播放和兼容性进行故障排除的过程：(audio and video playback and compatibility in PowerPoint:)
- 优化媒体的兼容性
- 检查编解码器
- 清除临时文件夹
- 转换受影响的媒体文件
- 压缩媒体文件
- 以安全模式(Safe Mode)打开Microsoft PowerPoint
让我们更详细地讨论这个问题。
1]优化媒体的兼容性
首先，您需要优化媒体兼容性(Optimize Media Compatibility)。为此，请转到“文件”菜单并选择“信息”选项。
如果您的演示文稿的媒体格式与其他设备存在兼容性问题，“优化兼容性(Optimize Compatibility)”选项将在您的计算机屏幕上闪烁。如果该选项未出现，则表示该演示文稿完全兼容，您可以轻松共享该演示文稿。
接下来，选择优化兼容性(Optimize Compatibility)。当您确认操作时，PowerPoint将运行用于改进需要优化的媒体的过程。
之后，将在演示文稿中出现的媒体数量列表旁边显示潜在播放问题的解决方案的完整摘要。它还将列出播放问题的原因。
如果您在演示文稿中附加了链接视频，“兼容性优化”功能将要求您嵌入它们。为此，请选择“查看链接”。然后，要嵌入视频，请为所需链接选择断开链接选项。(Break Link)
请记住，只有当您的演示文稿中有与(Bear)PowerPoint不兼容的视频或音频文件时，才会出现优化选项。
2]检查编解码器
您需要确保在 Windows 系统上安装了必要的编解码器。
默认情况下，Windows 10 不支持所有媒体编解码器，因此如果您想更改它，您需要下载众多编解码器包之一。从我们的角度来看，K-Lite Codec Pack是最好的选择之一，所以请继续检查一下。
3]清理TEMP文件夹
要解决PowerPoint中的视频和音频问题，您应该做的第一件事就是清除TEMP文件夹。这是一个简单的任务，所以让我们解释一下如何完成它。
如您所知，当您的TEMP文件夹中堆积了许多文件时，PowerPoint应用程序可能会显着降低速度。为避免这种情况，请定期检查不需要的文件并将其从TEMP文件夹中删除。要找到您的TEMP文件夹，试试这个！
关闭PowerPoint和您正在使用的所有其他程序。现在，单击Start > Run。然后，在出现的打开(Open)框中输入以下文本，%temp%并点击 OK。选择 .tmp 文件，然后按DELETE。
4]转换受影响的媒体文件
如果上述每个选项都无法按预期工作，则将媒体文件转换为适用于PowerPoint(PowerPoint)的格式是有意义的。如果要转换视频，我们建议使用 Windows 10 中内置的视频编辑器(Video Editor)工具。
说到音频，看看VLC 媒体播放器(VLC Media Player)提供什么怎么样？这是相当不错。
5]压缩媒体文件
解决此问题的另一种方法是从PowerPoint中压缩媒体文件。这可以通过单击File > InfoMedia Size and Performance下选择Compress Media。从弹出菜单中选择正确的选项，然后坐下来等待程序压缩所有文件。
6]以安全模式(Safe Mode)打开Microsoft PowerPoint(Open Microsoft PowerPoint)
如果一切都失败了，您可能需要在安全模式下打开(Safe Mode)PowerPoint ，看看您是否可以让您的音频和视频正常工作。为此，请按住CTRL按钮，然后双击PowerPoint快捷方式以在安全模式下(Safe Mode)打开它。
插入或播放媒体时遇到问题？
验证您是否安装了正确的编解码器。如果没有，请安装所需的编解码器以运行媒体。您甚至可以下载适当的第三方媒体解码器和编码器过滤器，以便对各种格式进行解码和编码。
为什么PowerPoint中的音频(Audio)和视频声音低(Video Sound Low)？
转到包含音频的幻灯片并查找扬声器图标。选择它，然后单击音量图标。您现在可以增加或减少音量。如果这没有帮助，则问题出在音频文件上，您需要更改或使用其他软件来增加音量。
PowerPoint中的音频格式选项卡在哪里？
当您选择音频文件并提供与音频相关的选项时，该选项卡会出现。除此之外，还会出现一个播放(Playback)选项卡，可以对音频进行精细控制，包括书签、定时音频、音量控制等。
Audio and Video does not play in PowerPoint
Some of the problems you maу fасe while working with Microsоft’ѕ PowerPoint application can be audio and video problems. PowerPoint users report, sometimes, that when they send their presentation through e-mail, the recipients are unable to play the presentation. It just refuses to load. Although the problem is rarely experienced, it can be a cause of concern in some instances.
Audio and Video does not play in PowerPoint
If your Audio and Video does not play in PowerPoint, then this post will walk you through the process of troubleshooting audio and video playback and compatibility in PowerPoint:
- Optimize media for compatibility
- Check Codecs
- Clear the Temp folder
- Convert the affected media files
- Compress media files
- Open Microsoft PowerPoint in Safe Mode
Let us talk about this problem in a more detailed manner.
1] Optimize media for compatibility
First, you need to Optimize Media Compatibility. For this, go to the ‘File’ menu and select the ‘Info’ option.
If the media format of your presentation has compatibility issues with other devices, the Optimize Compatibility option will flash on your computer screen. If the option doesn’t appear, it means the presentation is fully compatible, and you can readily share the presentation.
Next, select Optimize Compatibility. When you confirm the action, PowerPoint will run the process for improving media that requires optimization.
After that, a complete summary of resolutions of potential playback issues will be displayed alongside a list of the number of media occurrences in the presentation. It will also list the causes of playback issues.
If you have linked videos attached to your presentation, the ‘Optimize for Compatibility’ feature will request you to embed them. For doing so, select ‘View Links. Then, to embed a video, select the Break Link option for desired links.
Bear in mind that the optimize option will only appear if you have a video or audio file in your presentation incompatible with PowerPoint.
2] Check Codecs
You need to ensure that you have the requisite Codecs installed on your Windows system.
Windows 10, by default, does not support all media codecs, so if you want to change that, you will need to download one of the many codec packs. From our point of view, K-Lite Codec Pack is one of the best options out there, so go ahead and check it out.
3] Clean out the TEMP folder
One of the first things you should do to solve video and audio problems within PowerPoint is to clear the TEMP folder. It is a simple task, so let us explain how to accomplish it.
As you know, when you have many files piled up in your TEMP folder, the PowerPoint app can slow down dramatically. To avoid this situation, check periodically for unwanted files and delete them in your TEMP folder. For locating your TEMP folder, try this!
Close PowerPoint and all other programs you are using. Now, click Start > Run. Then, in the Open box that appears to enter the following text, %temp% and hit OK. Select the .tmp files, and then press DELETE.
4] Convert the affected media files
Should every option above fail to work as intended, it makes sense to convert the media file to formats that work with PowerPoint. If you want to convert video, we suggest using the built-in Video Editor tool in Windows 10.
When it comes down to audio, how about checking out what VLC Media Player offers? It’s pretty good.
5] Compress media files
Another way to solve this problem is to compress the media files from within PowerPoint. This is quickly done by clicking on File > Info, then selecting Compress Media under Media Size and Performance. Select the right option from the pop-up menu, then sit back and wait for the program to compress all files.
6] Open Microsoft PowerPoint in Safe Mode
If all else fails, you may want to open PowerPoint in Safe Mode to see if it is possible for you to get your audio and video working as they should. To do this, press and hold the CTRL button, then double-click on the PowerPoint shortcut to have it opened in Safe Mode.
Getting trouble while inserting or playing media?
Verify if you have the correct codec installed. If not, install the required codec to run the media. You can even download appropriate third-party media decoder and encoder filters to let you decode and encode a variety of formats.
Why is Audio and Video Sound Low in PowerPoint?
Go to the slide which has the audio and looks for a speaker icon. Select it, and then click on the volume icon. You can now increase or decrease the volume. If this doesn’t help, the problem is with the audio file, and you will need to change or use another software to increase the volume.
Where is the audio format tab in PowerPoint?
The tab appears when you select an audio file and offers options related to audio. Along with this, a Playback tab also appears that offers fine control on the audio, including bookmark, timing audio, volume control, and more.
