Simply Bad
First of all, Welcome to NG.
Secondly this is really bad. Honestly bud, if you use a model you downloaded off the net, at least tweak or change it in some way to make it original.
Next if you use 3d in Flash try exporting a .dae file and load it with papervision. At least then you won't see the massive quality drop when dropping a video directly onto the time-line and trying to optimize it for the limit.
Best of luck to you in the future
