So I have googled how to do this already but all the answers were for older versions of unity and use things that are not applicable anymore.
I am trying to do is fade the screen to white when the player wins, followed by a change to another level that will have a video playing.
How do I do this in Unity 5 (preferably in C#)?
You can use the UI Canvas. Add a panel to the canvas and set the color to your preference. After you get that set up you could animate that panel to do anything from changing colors to custom sliding effects ect...
To implement something like this you would want
Animator anim;
//in Awake()
anim = GetComponent <Animator> ();
// Tell the animator that the player Won.
anim.SetTrigger ("Win");
//then after the Win animation is finished trigger a Application.LoadLevel("yournextscene");
