I am new to visionlab, and just need an affect that looks like a book or something has dropped on the ground, and dust poofs out from under it.

I bet if you use the ambient smoke preset, and change the size of the particle, you can get a pretty decent "poof". smile

Wouldn't it be far easier and more realistic to create a practical dust poof when you drop the book while filming?

I agree with Axeman, a simple bit of powder or flour even gently applied to the underside of the book would be fine.

I'm playing around with the particles right now. I've been able to get a pretty good 'poof' biggrin I'll let you know if it gets put in the preset library.

OK. I got the preset posted. As mentioned in the description, it works best to put the footage on a layer on top of the preset.

If you put your footage over the preset... then you won't be able to see the preset. Unless you make the footage transparent somehow. Could you explain what you mean a bit more please?

Well this is a little difficult to explain but in the picture below it shows the tracks with the preset on the top:

When you do that it produces something like this:

So the object even gets slightly obscured.
Now, lets do it the right way:

Which produces this:

Much better...
I hope that explains it.

Yeah, I can see that it looks better in the second one, but what are you doing to the footage layer to allow the preset to be visible through it? Do you have more than one layer of footage, with the dust sandwiched between them? Or are you altering a transparency setting or composite mode somewhere?

Hmmm, I'm not exactly sure what you're talking about but let's see:
I have the particles drawn in front
The footage is on Screen composite
And the preset is on Normal Composite

If this isn't what you're looking for, then, could you be a little more specific?
