How do I make a cut scene unity free
You use in-game models and scripting, probably. Since you can’t use movie textures in Unity Free I think you’re basically SOL.
Why SOL? You only need to use movie textures if you want to play back a pre-rendered cut scene. That is one way to do it, but it is certainly not the only way.
One thing you could do, and this ought to work in Free, is to use your models and cameras directly in game at run time to show your cut scene. In other words, simply take control away from the player, place your models and cameras (via script), run your animations and sound, and when done, give control back to the player.
This is exactly what I’m planning on doing (I have Pro, but since my player can be customized (face, body and clothing) and I want the cut scenes to respect those customizations, I cannot use pre-rendered scenes). I haven’t set it up yet, but I don’t really foresee much difficulty in doing so. It seems like a relatively simple procedure
Sorry to wake an old post, but one way to do it would be to rip the movie into individual images, then load them in sequence.
Or you could bite the bullet and import the WHOLE ANIMATION into unity as a model, then set up shaders, cams, lights, etc… 
I do this for animated logos in my games.
