# Adding Image Overlays to Videos in .NET

Video Edit SDK .Net VideoEditCoreX

Our .NET SDK provides powerful functionality for adding image overlays to your video projects. With this feature, developers can seamlessly integrate logos, watermarks, graphics, and other visual elements into video content. The SDK offers extensive customization options including precise positioning, transparency adjustment, and timing control.

The SDK is compatible with all standard image formats used in professional video production:

• BMP (Bitmap)
• GIF (Graphics Interchange Format)
• JPEG/JPG (Joint Photographic Experts Group)
• PNG (Portable Network Graphics)
• TIFF (Tagged Image File Format)

Below you'll find detailed code examples demonstrating how to implement image overlays in your video processing applications using our SDK.

The following code sample demonstrates how to add an image overlay with custom positioning, transparency, and timing using the VideoEditCoreX engine:

// add an image overlay to a video source effects from PNG file
var imageOverlay = new ImageOverlayVideoEffect("logo.png");

// set position
imageOverlay.X = 50;
imageOverlay.Y = 50;

// set alpha
imageOverlay.Alpha = 0.5;

// set start time and stop time
imageOverlay.StartTime = TimeSpan.FromSeconds(0);
imageOverlay.StopTime = TimeSpan.FromSeconds(5);

// add video source to timeline
VideoEdit1.Video_Effects.Add(imageOverlay);

For developers working with the VideoEditCore engine, here's how to achieve the same functionality:

var effect = new VideoEffectImageLogo(true, name);

   // set position
   effect.Left = 50;
   effect.Top = 50;

   // set alpha (0..255)
   effect.TransparencyLevel = 127;

   // set start time and stop time
   effect.StartTime = TimeSpan.FromSeconds(5);
   effect.StopTime = TimeSpan.FromSeconds(15);

VideoEdit1.Video_Effects_Add(effect);

When implementing image overlays, consider these additional configuration options:

• Positioning: Adjust X/Y or Left/Top values to place your overlay precisely
• Transparency: Configure Alpha or TransparencyLevel to control overlay opacity
• Timing: Set StartTime and StopTime to determine when the overlay appears and disappears
• Size: You can resize overlays to fit your specific requirements
