Use Unity’s video system to integrate video into your game. Video footage can add realism, save on rendering complexity, or help you integrate content available externally.
To use video in Unity, import Video Clips and configure them using the Video Player component. The system allows you to feed video footage directly into the Texture parameter of any component that has one. Unity then plays the Video on that Texture at run time.
Note: The Video Player component and Video Clip asset, introduced in Unity 5.6, supersede the earlier Movie Textures feature.
