Trapcode Particular question
Ok I'm doing smoke in a scene and i cant seem to be able to slow the smoke down.
Here is a clip so you see the issue: 37megs - http://tadamedia.com/_Dropbox/fastsmoke.mov
On other issues im having is I tracked the shot, applied the motion to a null, then parented all the smoke layers to the null. Now the smoke seems to be reacting to the physical camera motion.

As far as the smoke goes, the first thing I would do is play with the velocity and gravity settings. Good chance you've already done that though, so sorry if I'm wasting your time.
For the second issue, when you say physical camera, are you referring to the camera that shot the footage? If so don't you want the smoke to react to the camera?

I'll look into the gravity. I played with the velocity already and it kind of helped.
As for the camera, i am talking about the camera that shot the footage. In reality the camera man moving back and forth wouldn't affect the smoke in the distance. I may have to precompose it then parent that layer to my null object.

So i added gravity, big help! Then stretched the duration to 300%. That did it.
Not my idea of an ideal fix, but it will get it out the door in time for the deadline.
Thanks Kyle!

Hey Josh, glad that worked for you. As for the camera problem, I'm not completely sure if it's a problem or not. I just watched your video again and didn't think there was anything too out of the ordinary. The smoke you composited moves similar to the tree line. Since the viewer is being lead to believe that the smoke and the treeline are close to each other or at similar depths as part of the background, they would move at a similar speed.

I presented it to the director and he agrees it looks good enough. After they color grade it you'll never know it was composited. Wahoo. That means I'm done!
Thanks for your help!

A bit late to the convo and dunno if it helps, but have you tried playing with air resistance ?

I think your "smoke reacting to the camera" might be the result of the "Velocity from motion" setting (2 below the Velocity property under the Emitter controls).
Since you applied the tracking data to the emitter, it now moves (even though the smoke is technically NOT moving in the composite, your emitter is.) "Velocity from motion" makes the particles continue on the trajectory they inherit from the emitter at their time of birth. Tru turning that setting to 0 and see if that fixes it... even though the shot's approved, still a good learning experience!!
