**Why the PPT Video Encoder Is Not Available:**
The WMA audio file you inserted is not compatible with PowerPoint, even though a codec may be installed. While the file can play in other media players on your computer, it might not work properly within PowerPoint. To fix this issue, use compatible WMA files or convert them to Windows Media Audio format, which is widely supported and commonly used online. This ensures smoother playback and better compatibility when presenting in PowerPoint.
**Inserting AVI, ASF, ASX, MLV, MPG, WMV Files:**
There are several ways to insert video files into PowerPoint:
1. **Using the "Insert Movie" command** from the "Insert" menu is the most common and straightforward method.
2. **Using the "Insert Object" command** allows you to embed an object directly.
3. **Using Insert Control**: This method requires that Windows Media Player or RealPlayer is installed. Here’s how to do it:
- Open PowerPoint and go to the slide where you want to insert the video.
- Go to the "View" menu, then select "Toolbars" and enable the "Control Toolbox."
- Click the "Other Controls" button, choose "Windows Media Player," and draw a rectangle on the slide.
- Right-click the player window, select "Properties," and enter the full path of the video file in the "URL" field.
- During the slideshow, you can control the video using the built-in buttons like Play, Stop, Pause, and Volume.
**How to Insert RM, RA, RMVB Files:**
While Windows Media Player supports formats like AVI, MPG, and WMV, it does not support RM files. To play RM videos in PowerPoint:
1. Ensure RealPlayer is installed on your system.
2. Open the slide and go to the "View" menu to open the "Control Toolbox."
3. Click "Other Controls" and select "RealPlayer G2."
4. Draw a rectangle on the slide, right-click it, and enter the full path of the RM file in the "Source" field (e.g., 8.rm).
5. Set "AutoStart" to "False" so the video doesn’t play automatically.
6. You can now control the video using RealPlayer’s interface during the presentation.
**How to Insert FLV Videos into PowerPoint:**
There are multiple methods for inserting FLV files:
1. **Hyperlink Method**: Insert a hyperlink to the FLV file, but this isn’t ideal as it opens a separate window.
2. **Conversion Method**: Convert FLV to AVI or MPG using software, but this reduces quality and increases file size.
3. **Packing Method**: Import FLV into Flash and export as SWF, then insert using the Shockwave Flash Object.
4. **Control Method**: Use the Windows Media Player control after installing an FLV decoder like K-Lite Codec Pack:
- Insert the Windows Media Player control.
- Enter the FLV file path in the "URL" field.
- Control playback using the built-in buttons during the slideshow.
5. **Player Method**: Create a custom FLV player in Flash (SWF), then insert it using the Shockwave Flash Object control. This is more complex but offers greater flexibility.
By following these steps, you can easily insert various video formats into PowerPoint and have full control over playback. Choose the method that best suits your needs and technical level.
