Add a new video into the videos collection of the presentation using Presentation.Videos.AddVideo() method and get its reference into an IVideo object.
Add a new video frame in the slide using ISlide.Shapes.AddVideoFrame(single, single, single, single, IVideo) method.

	// Get the first slide
	ISlide sld = pres.Slides[0];

	// Add video to presentation
	IVideo vid = pres.Videos.AddVideo(new FileStream("Wildlife.mp4", FileMode.Open));

	// Add video frame
	IVideoFrame vf = sld.Shapes.AddVideoFrame(50, 150, 300, 350, vid);

	// Assign video to video frame
	vf.EmbeddedVideo = vid;

	// Set play mode and volume of the video
	vf.PlayMode = VideoPlayModePreset.Auto;
	vf.Volume = AudioVolumeMode.Loud;

Embed Video in Presentations from a Web Source

You can also embed a video in the PowerPoint presentations from a web source. The following are the steps to achieve this.

First, load the PowerPoint file or create a new one using Presentation class.
Then, get reference of the desired slide in an ISlide object.
Add a new video frame in the slide by specifying the video’s URL in ISlide.Shapes.AddVideoFrame(single, single, single, single, String) method.
Get reference of the video frame into an IVideoFrame object.
Set the play mode and volume of the video.
Set thumbnail of the video using a WebClient.
Save presentation using Presentation.Save(String, SaveFormat) method.

The following code sample shows how to embed a video into the presentation from a web source.

	using (Presentation pres = new Presentation())
	{
	// Video ID
	string videoId = "Tj75Arhq5ho";

	// Add video frame
	IVideoFrame videoFrame = pres.Slides[0].Shapes.AddVideoFrame(10, 10, 427, 240, "https://www.youtube.com/embed/" + videoId);
	videoFrame.PlayMode = VideoPlayModePreset.Auto;

	// Load thumbnail
	using (WebClient client = new WebClient())
	{
	string thumbnailUri = "http://img.youtube.com/vi/" + videoId + "/hqdefault.jpg";
	videoFrame.PictureFormat.Picture.Image = pres.Images.AddImage(client.DownloadData(thumbnailUri));
	}

	// Save presentation
	pres.Save("AddVideoFrameFromWebSource_out.pptx", SaveFormat.Pptx);

Extract Video from a PowerPoint Presentation in C#

Aspose.Slides for .NET also allows you to extract a video from a presentation. Below are the simple steps to achieve this.

First, load the PowerPoint file using Presentation class.
Then, loop through each ISlide in Presentation.Slides collection.
For each ISlide object, loop through the collection of IShape in it.
If IShape is a VideoFrame, then extract and save the embedded video.

The following code sample shows how to extract videos from a PowerPoint presentation using C#.

	// Load a presentation file
	Presentation presentation = new Presentation("Video.pptx");

	// Loop through slides in the presentation
	foreach (ISlide slide in presentation.Slides)
	{
	// Loop through shapes
	foreach (IShape shape in presentation.Slides[0].Shapes)
	{
	if (shape is VideoFrame)
	{
	// Extract and save video
	IVideoFrame vf = shape as IVideoFrame;
	String type = vf.EmbeddedVideo.ContentType;
	int ss = type.LastIndexOf('/');
	type = type.Remove(0, type.LastIndexOf('/') + 1);
	Byte[] buffer = vf.EmbeddedVideo.BinaryData;
	using (FileStream stream = new FileStream("NewVideo_out." + type, FileMode.Create, FileAccess.Write, FileShare.Read))
	{
	stream.Write(buffer, 0, buffer.Length);
	}
	}
	}
	}
