Hi I am looking for a simple way to generate a smoke effect in after effects. Maybe something like this:
<div style="width:240;height:280"><object width="100%" height="100%"><param name="movie" value="http://shorts.creativecow.net/player/player.swf?vid=3990"></param><param name="scale" value="noscale" /><param name="allowFullScreen" value="true" /><param name="allowscriptaccess" value="always" /><embed src="http://shorts.creativecow.net/player/player.swf?vid=3990" type="application/x-shockwave-flash" width="100%" height="100%" scale="noscale" allowFullScreen="true" allowscriptaccess="always"></embed></object></div>
I simply want to have white (or some other coloured) smoke on a transparent background, so that I can export it as a flash file and use as an overlay on a webpage i am designing (the smoke coming out of a test tube in a static image).
I would be grateful for any advice in creating this effect,
Typically, digital smoke is generated using a particle generation system. The smoke in your example video is considerably more complex. You may get better results using real-world footage. Try a stock video site like iStockphoto or Artbeats. Or, try shooting the smoke yourself - a cigarette against a black background, for example.
Try experimenting with CC Particle World and CC Particle System to see what simple particle generators are capable of.

Shoot it, buy stock footage, learn a 3D program. If it were that easy, then there would be no need to have a few hundred highly specialised people work on big Hollywood movies, plain and simple. Even more to the point, it is often just much easier and cost efficient to do such things as practical effects. You know, the time it would take to setup a simulation and calculate it will massively bump up costs and it's often not in the budget. If you realyl must create it artificialyl, your best option in AE would be the Turbulence2D plug-in. Apart from that, you could just look into free fluid simulation tools such as e.g. the respective Pixel Bender graph at derschmale.com
