Adding high-quality videos to a slide presentation can greatly increase the impact that it has on your viewers. To emphasize or control media that you use in your presentations, you can adjust, display, or update various properties associated with that media. In this topic, you insert a video into a Microsoft PowerPoint 2010 presentation and then programmatically display and update the properties of that video. To complete this task, you must do the following:

In this task, you insert a sample video file into the PowerPoint 2010 presentation.

To insert a video file

  1. Download the PowerPoint 2003 sample video.

  2. Start PowerPoint 2010.

  3. Delete the shapes from the first slide.

  4. On the Insert menu, click Video, and then click Video from File.

  5. Navigate to the sample video file and then click Insert.

  6. Resize the video so that you can see it better, and then play it to make sure that there are no problems. Note the length, the beginning and ending times, and the volume of the video.

In this task, you open the Visual Basic Editor, and then insert a standard module.

To add a standard module to a PowerPoint presentation

  1. On the Developer tab, click Visual Basic to open the Visual Basic Editor.

    Note Note

    If you do not see the Developer tab in PowerPoint, click the File tab, and then click Options. In the categories pane, click Popular, select Show Developer tab in the Ribbon, and then click OK.

  2. On the Insert menu, click Module. This adds Module1 to the Projects pane on the left side of the Visual Basic Editor.

In this task, you add Microsoft Visual Basic for Applications (VBA) code that displays several properties related to the sample video, and then updates some of those properties.

To add code to the Visual Basic Editor

  1. In the Projects pane, click Module1.

  2. Paste or type the following code into the module window.

    Sub MediaFormatInfo()
        Dim shp As Shape
        For Each shp In ActivePresentation.Slides(1).Shapes
            ' Is it a media shape?
            If shp.Type = msoMedia Then
                Debug.Print "Media Element: " & shp.Name
                DisplayMediaFormatInfo shp
               
                ' Work with the MediaFormat property:
                With shp.MediaFormat
                    ' Modify the values that can be modified:
                    ' Start at 2 seconds, end at 5 seconds,
                    ' fade in and out for 1/2 second:
                    .StartPoint = 2000
                    .EndPoint = 5000
                    .FadeInDuration = 500
                    .FadeOutDuration = 500
                   
                    ' Ensure the video isn't muted, and
                    ' that the volume is lower than max:
                    .Muted = False
                    .Volume = 0.25
                End With
            Debug.Print "================"
            DisplayMediaFormatInfo shp
            End If
        Next shp
    End Sub
    
    Private Sub DisplayMediaFormatInfo(shp As Shape)
        With shp.MediaFormat
            ' Retrieve all the useful properties:
            Debug.Print vbTab & "AudioCompressionType: " & .AudioCompressionType
            Debug.Print vbTab & "AudioSamplingRate: " & .AudioSamplingRate
            Debug.Print vbTab & "EndPoint: " & .EndPoint
            Debug.Print vbTab & "FadeInDuration: " & .FadeInDuration
            Debug.Print vbTab & "FadeOutDuration: " & .FadeOutDuration
            Debug.Print vbTab & "IsEmbedded: " & .IsEmbedded
            Debug.Print vbTab & "IsLinked: " & .IsLinked
            Debug.Print vbTab & "Length: " & .Length
            Debug.Print vbTab & "Muted: " & .Muted
            Debug.Print vbTab & "ResamplingStatus: " & .ResamplingStatus
            Debug.Print vbTab & "SampleHeight: " & .SampleHeight
            Debug.Print vbTab & "SampleWidth: " & .SampleWidth
            Debug.Print vbTab & "StartPoint: " & .StartPoint
            Debug.Print vbTab & "VideoCompressionType: " & .VideoCompressionType
            Debug.Print vbTab & "VideoFrameRate: " & .VideoFrameRate
            Debug.Print vbTab & "Volume: " & .Volume
        End With
    End Sub
    

In this task, you run the VBA code. The code displays the property values in the Immediate window.

To run the code

  1. If you do not see the Immediate window, click View, and then click Immediate Window.

  2. To single step through the code, place the cursor in the MediaFormatInfo procedure, and then press F8. Observe the results in the Immediate window as you step through the code.

  3. After you run all of the code, press Alt + Q to close the Visual Basic Editor and move back to the presentation.

  4. Run the video. Note the changes in duration and volume of the video.
