Have you noticed that your embedded Flash video looks like crap if you scale your flash file up or down?
A lot of people don’t realize this, but you can actually apply smoothing to flash video, just as you can to a bitmap image.
All you have to do is apply the following Actionscript 3 code to your video clip instance:
for example, say your video clip instance is called ‘video’
video.getVideoPlayer(video.activeVideoPlayerIndex).smoothing = true;
That’s it! Now you can scale your flash video along with your other graphics. If you plan to scale up, be sure to use a video with a greater resolution than you need, so that you can get the best results. Scaling down will just simply work.
