Q&A for How to Embed Video in PowerPoint

Save the file as an mp4, then insert it into PowerPoint.

Yes, it should still work.

Try using a lower quality video or closing other programs, it may be that your computer is struggling to play the file.

If the video is large, use DropBox or some version of it. The video will be embedded in the ppt file, and will be larger than in a usual email.

Simply select the video within the slide; this will make a new tab appear across the top called Playback. Within that tab is a tick box called "Play Full Screen"; once this is checked, when you view the slide show the video will appear full screen.

You could put the videos on a USB stick and arrange a time and day to meet to give it to the person.

Select the video, and rotate it like a textbox. Take note that the video itself should be embedded to the PowerPoint presentation, so earlier versions like PowerPoint 2007 cannot do this.

As long as it is embedded, it should play. However, linked videos would not work, because they are not present on the PowerPoint file.

Unfortunately, there is no way to do that, at least not until PowerPoint 2013, where multiple displays are introduced to avoid showing video progress bars while presenting. If it is necessary (for PowerPoint 2010 and earlier), play the video using Alt + P, and avoid using mouse, or animate the 'play video' as part of your slideshow.

Make sure that the video does not block the image you are showing. Bring the image to the front (and if necessary, animate it so it would show up after the video playback). If you cannot do that, try to drag the video to the side, then select the image. Or use selection pane, then do the things aforementioned.

If your embedded video appears as a picture or disappears after saving your PowerPoint presentation, consider the following troubleshooting steps: ensure you are using the "Insert → Video" option, not "Insert → Picture"; select "This Device" or "Online Video" for proper insertion; save your presentation in the .pptx format, avoiding image or older file types; if the video is linked, keep the video file in the same folder as your PowerPoint presentation; and verify that you are viewing the presentation in Normal or Slide Show mode, as read-only viewers may not play videos.
