Tracking moving objects that move themselves.
Ok so I have footage from finallight.com . Its footage of a missle fire with a trail of smoke. I have footage I shot that is handheld. I then track the handheld footage. Now that I have my fire trail tracked to x and y to the bakcground plate I shot it doesnt move and the track worked well. The only problem is since the smoke is moving and I cant move the scale because its tracked info how do i animate the fire trail to shoot(move) thru the scene? When I move the anchor point it just moves the whole fire trail and the smoke does NOT animate. Any help would be wonderful

I’m not sure I understand the elements that you have or what you trying to get, but I’ll ask some questions that might help.
Does the missile move thru the frame on the original shot or did the shooter track along with it?
If the missile moves thru the original frame then tracking the camera move of your background element and applying that tracking data to the missile footage would get the camera’s movement added to the motion of the missile thru the frame.
By the way, You might want to apply the track to a null and parent the the missile footage to the null, this gives you the ability to make some adjustments to the layer but still have the camera motion.
If your missile does not move thru the original frame then you need to use the null method but add motion thru the frame by animating the missile footage in the way you want. You might animate the missile footage first then parent it to the null layer and check to make sure it is still working for you.
Keep in mind that if your trying to create a shot that looks like someone photographed a missile moving thru some area, that people will not always keep the missile right in the center of the frame. (i.e. they pan over and sightly passed the missile then move back to a better framing as they begin to track along with the missile)

Thanks a production bundle tony. Basically the footage is from finallight.com under freefx. Its the fireball with a smoke trail. So when you open the quicktime file its just sitting there animating. Meaning the fireball is still but its animating so the smoke is moving and the fire is moving but not through the footage for instance from left to right.

Ok you might just try moving that footage layer across your background footage without tracking and see if you find that it looks like what you wanted, if not try my second suggestion about tracking and applying it to a null, animating the footage across the frame then parenting it to the null.
Good luck
