Adding video to Chess game (On attack)

I'll give you guys a short introduction to our game. Ever saw the game Battle Chess? It's just like that. Now for our problem. We insert a video every time the chess pieces eat another chess piece. But different video to every chess piece battle combination , like a different video for pawn to pawn or and different video for pawn to queen. I don't know what and which codes to use cause we don't have a lot of experience with scripting in Unity. Could you guys please help us? We could send you our codes if you need em to help us. Thank you very much in advance.

 

I'm assuming this is now available to everyone in Unity 5 - but I haven't verified: http://docs.unity3d.com/Manual/class-MovieTexture.html

Otherwise you could just go with traditional 3d animation/2d sprites depending on what you're doing...
