Need help creating a transition effect

Let me clarify that I am faily new to AS3 and actionscript in general. The effect I’m trying to achieve is to have my flv movie embedded in the flash piece animate in a box type transition, scaling the X & Y from 0 to 100% over 25 frames. I have absolutely no idea where to start, any help would be greatly appreciated. This is the code I have so far:

// Video Stream/Connection

var nc:NetConnection = new NetConnection();

var ns:NetStream = new NetStream(nc);
ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler);“test.flv”);

function asyncErrorHandler(event:AsyncErrorEvent):void
// Ignore Error

var vid:Video = new Video();
vid.x = 405;
vid.y = 7;
vid.deblocking = 0

// Video Playback
function playHandler(event:MouseEvent):void
btn_Play.addEventListener(MouseEvent.CLICK, playHandler);
