2. Edit MPEG or AVI video files. Next we will edit the movie or video clips to show exactly the portion of the video you want included as a clip on your PowerPoint presentation. To do this we will use the free software provided with all Windows XP licenses called Movie Maker although you could use many other programs such as TMPencDVD Author for example . Find Windows Movie Maker on your PC (typically by selecting Start-Programs-Accessories) and open it. On the left under "capture video" you will see "import video". Select that and select your video clip from the appropriate folder. That will import the video and break it up into several smaller clips. For the next steps, watch the video below on how to use Windows Movie Maker to edit the video clip:
One thing you might need to do in Windows Movie Maker is to increase or decrease the volume level of the video clip. To do that, on the Audio or Audio/Music track of the timeline, select the audio clip whose volume you want to adjust. Then click Clip, point to Audio, and then click Volume. To adjust the volume, do one of the following:
To reduce the volume, slide the Audio volume level slider to the left.
To increase the volume, slide the Audio volume level slider to the right.
To mute the clip, select the Mute clip check box.
To reset the volume to the original volume, click Reset.
3. Add Clip to PowerPoint. Now that you've edited the video clip, just save it. There are two methods of playing video during a PowerPoint presentation.
You can embed the video clip into a slide by going to the point where you want the video inserted, select Insert Menu-Movies and Sounds+Movie from File. Find the movie file in your folder and double-click on it. PowerPoint will then import the file and then you can reposition or resize the clip.
