# How to add video effects?

# Sample code

C# sample code for lightness effect in Media Player SDK .Net.

The same API is available for Video Edit SDK .Net and Video Capture SDK .Net.

Define effect interface:

IVideoEffectLightness lightness;

Get interface instance from SDK control. If the effect is not added before, you'll receive a null value. Each effect must have a unique name.

var effect = MediaPlayer1.Video_Effects_Get("Lightness");

If the effect does not exist, we'll add it.

if (effect == null) 
{ 
    lightness = new VideoEffectLightness(true, 100);
    MediaPlayer1.Video_Effects_Add(lightness); 
}

Or, we need to apply a new value to effect.

else
{
   lightness = effect as IVideoEffectLightness;
   if (lightness != null)
   {
      lightness.Value = 100;
   }
}

You must set the Video_Effects_Enable property to true before the Play() or Start() method call to use video effects.
