fog effect

Hi folks,

Does anyone know how to create a fog effect? I want to have some coloured, moving fog over a title (on a black bacground)

I thought of creating it in iMovie using its pre-made filter, then importing it into FCE, but no luck there. I can't get it to work over a black clip in iMovie without a title also being there, and don't much like the title options in iMovie.

I've tried the free plugin offered by CHV (the Silk and Fog one) but that is static fog - no wind moving it - which is not what I'm after.

Any ideas?

Thanks,
Andrew

What if you make the title in iMovie, but instead of putting in text just put in some spaces with the spacebar. I haven't tried it in iMovie but similar things work in other applications.

can you get the fog into final cut? is there a way to change the file so that final cut will accept it so you can add it to a timeline?

Thanks for that Tom. What you've suggested works, but there's some weird thing happening with the fog itself when I import the QuickTime file from iMovie. In iMovie the fog looks quite realistic, but in FCE it looks more like a lava lamp!

Oh well, at least you got me past my first hurdle.

Thanks and regards,
Andrew

I've tried Tom's suggestion and it works, but the results aren't good (see my reply to Tom).

Hamilton: Simply import the iMovie file into FCE as I described in your post "Fog 2" and it will play perfectly - any sound will need rendering.

Ian.

How are you exporting from iMovie? Are you bringing transparency information in from iMovie? If so set the alpha channel in FCE to premultiply with black. You can do this in the Browser columns or in item properties.

Tom,

I'm exporting from iMovie by dragging the clip from the Timeline onto the Desktop. Then I go to FCE > Import.

I don't know if transparency information is being brought with the clip - it's the first I've heard of the term.

How do I set the alpha channenl in FCE within the Browser or item properties? This is new terminology to me too.
