**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 other playback software on your computer can handle this format, PowerPoint does not support it directly. To resolve this issue, use compatible WMA files or compress sound files using Windows Media Audio. These types of files are commonly found and downloaded from the internet.
**Inserting AVI, ASF, ASX, MLV, MPG, WMV Files in PowerPoint:**
1. Use the "Insert Movie" command under the "Insert" menu – this is the most common and straightforward method.
2. Use the "Insert Object" command from the "Insert" menu.
3. Insert a control (such as Windows Media Player or RealPlayer) to play the video.
To insert a video via control:
(1) Open PowerPoint and go to the slide where you want to add the video.
(2) Go to the "View" menu, open the "Control Toolbox," and click "Other Controls."
(3) Select "Windows Media Player" and draw a rectangle on the slide. This will become the media player interface.
(4) Right-click the player, select "Properties," and enter the full path and filename of the video in the "URL" field.
(5) During the presentation, you can control the video using the built-in buttons like play, stop, pause, volume, and progress bar.
**How to Insert RM, RA, RMVB Files in PowerPoint:**
While Windows Media Player supports many video formats, it doesn't support RM files. To play RM videos in PowerPoint, you can either convert them to AVI or MPG using video conversion software — but this process can be slow and result in large file sizes. Alternatively, you can use the "Control Toolbox" to insert the video directly.
Here's how:
(1) Open the PowerPoint slide.
(2) Go to "View" > "Control Toolbox" > "Other Controls."
(3) Choose "RealPlayer G2" (ensure RealPlayer is installed), then draw a rectangle on the slide.
(4) Right-click the area, select "Properties," and enter the full path and filename of the RM file in the "Source" field. Set "AutoStart" to "False" so the video doesn’t play automatically.
This method allows you to control the video during the presentation using standard player controls.
**How to Insert FLV Videos in PowerPoint:**
There are several methods to insert FLV files into PowerPoint:
1. **Hyperlink Method:**
Insert a hyperlink to the FLV file, which opens in a separate window. This is simple but not ideal for seamless integration.
2. **Conversion Method:**
Convert FLV to AVI or MPG using video conversion software, then insert it via the "Insert Video" option. However, this reduces video quality and increases file size.
3. **Packing Method:**
Import the FLV into Flash, export as SWF, and insert the SWF file using the Shockwave Flash Object control. This method results in smaller files than AVI/MPG but still affects video quality.
4. **Control Method:**
Use the Windows Media Player control to play FLV files. First, install an FLV decoder like K-Lite Codec Pack. Then:
(1) Open the PowerPoint slide.
(2) Go to "View" > "Control Toolbox" > "Other Controls."
(3) Select "Windows Media Player" and draw a rectangle.
(4) In the properties, enter the FLV file’s path in the "URL" field.
You can now control the video with play, stop, pause, and volume functions. This is a recommended method.
5. **Player Method:**
Create an FLV player in Flash (e.g., flvplayer.swf), then insert it into PowerPoint using the Shockwave Flash Object. This is more complex but offers greater flexibility.
Each method has its pros and cons, depending on your needs and technical skills. By following these steps, you can easily embed various video formats into your PowerPoint presentations.
