You can insert videos in your presentations to add a little flair and emphasize your point. Just make sure to keep the videos short, so that they don't become the main event.
Videos that are inserted from a file are embedded directly into the PowerPoint presentation, so the presentation file size will increase when videos are inserted.
Click the Insert tab on the ribbon.
Click to expand the Media group.
Click Video.
Select Video on My PC.
If you don’t have a video saved to your computer, you can also choose Online Video to add a video from YouTube or use an embed code.
Navigate to and select the video.
Click Insert.
The video is inserted into the slide.
Just like with other objects, you can click and drag to resize or move the video.
Click Play to preview your video.
To delete a video, select the video and press the Delete key on your keyboard.
