We already showed how you can use the STAMP add-in for PowerPoint to manually add captions for videos right inside PowerPoint. While manually adding captions is a great way to get easily started, professional organizations use TTML files. TTML files are markup files, not too different in structure from HTML web pages, and typically they have the XML file extension.
To learn more, choose your version of PowerPoint. If we do not have a tutorial for your version of PowerPoint, explore the version closest to the one you use.
