Compress media

The MediaFormat object has two properties Resample and ResampleFromProfile which does this. More about the MediaObject here: http://skp.mvps.org/2010/ppt002.htm

Resample method allows custom settings to be applied to resample media.
Sub Resample([Trim As Boolean = False], [SampleHeight As Long = 768], [SampleWidth As Long = 1280], [VideoFrameRate As Long = 24], [AudioSamplingRate As Long = 48000], [VideoBitRate As Long = 7000000])

ResampleFromProfile is a little known method that allows you tap into the UI profile settings that are in the File | Info | Compress Media options specific to a shape.
Sub ResampleFromProfile([profile As PpResampleMediaProfile = ppResampleMediaProfileSmall])

When the resample begins, you will see the progress bar appearing on the status bar. If the presentation has never been saved to disk, resample will begin when the presentation is saved.

Supported versions: PowerPoint 2013 or later
