Extracting a video or photo from PPTX
If you need an embedded video extracted from PowerPoint it’s as simple as the following:
1) Rename the suffix of the .pptx file to .zip
2) You’ll get the following error
Just select “Use .zip”
3) Then open or unzip the file.
4) Open the folder PPT and then Media and you should find what you need.
This works with PowerPoint Mac 2011 as well as PowerPoint 2013 on Windows.
