Hi,
this might help:

Hi,
ps if you are just wanting to half the alpha something along these
lines should work as well:
var newbitmap:BitmapData = new BitmapData (widht, height, true, 0x0);
newbitmap.draw (oldbitmap, new Matrix(), new ColorTransform(1,1,1,0.5,0,0,0,0));

Hi Andrew,
As far as I remember, the YouTube .swf is a shell around an .flv.
So the dimensions of the shell .swf may bear absolutely no
resemblance at all to the size of the contained video; and off-hand, I
can't think of a way to get at the contained video size. But aren't
they all
Of course, it's a swf around a flv. This makes a bit more sense now.
My guess is that the size of the flv _will_ vary, after all there are
lots of different video formats. The YouTube shell is going to have its
own internal algorithms for computing the scaling of the flv and the
placement
