Particle positioning question

When adding particles to a moving object that is constantly spraying out the particles (a flame thrower for example) there is a trail of particles, but this gets messed up when the camera is moving too because then the trail goes all over the place and doesn't look good. Is there a way to fix this?

Try setting the position attribute to 'Stuck to origin' and the particle creation to 'Relative to animation'.

But can it still leave a trail?

I don't think I was clear enough on what I said.
By 'trail' I mean particles that aren't stuck to the origin, after they have been emited they are out of my control and when the camera shakes they shack with it. Is it even possible to stop this from happening? If not...it should be.

I would shoot with the camera on a tripod, (or use a still background), add the particles, render the video and add artificial camera movement to the rendered clip with the animation tools. This, I believe, is how Fxhome's particle demo video (with the fire in the window) was done. You will lose some quality, but if you don't scale it up too far it should look ok.
Hope this helps!

If you set them "stuck to origin" and animate the origin to match the movement of the scene, the trail shot forth should follow the motion.

Get a fluid head. It helps a heck of a lot.

Sorry but I don't think I get what you're saying.
Unless your just talking about standarldy animating it and not making it look like it isn't stuck to origin and still not following the camera movements.
After I read that myself I wonder if your going to get what I'm

You've had your answer. If you set "stuck to origin" then wherever you move the origin, the particles will always stay relevant to it. This is what you need if you have a shakey camera.
