  • Use a top layer to enhance certain parts of a lower layer?

    Posted by Phillr on June 21, 2006 at 4:59 pm

    I’m making a title animation that will include cast and name of the project. What I have is one layer with a few filters on it so it looks like the entire screen is covered with smoke. What i’d like to do is be able to ‘enhance’ parts of the smoke to spell out the name of whatever actor/actress.

    E.g. smoke is currently mostly dark grey. The word “John Doe” will ‘fade up’ with the smoke becoming a light gray/white for the letters.

    I’m *thinking* i’d do this possibly with an adjustment layer? I’ve never used adjustment layers before and i’m not infront of a AFX station right now :-(. I’m thinking I would use the text tool on the adjustment layer, type out the name, then use a brightness/contrast filter to make the smoke lighter/brighter? I’d only want this adjustment layer to be affecting the smoke layer, as there will be a few video clips behind the smoke.

    Here is an idea from another thread…sounds different than what you are trying to do, however. This thread takes you to ayatoweb.com site, where there is an interesting effect of text from “smoke”…

    I hope, this is understandable – my english could be better.

    Try this: create a new comp “TEXT”. Create your text in it, that means for every appearance you create another layer, and one layer follows the other in time. The kind of transition is up to your imagination.
    Create another comp and place your composition with the smoke in it, which is your bottom layer in this comp now. On top of this layer place an adjustment layer. Next drag and drop the text-comp on top of this comp. Locate your adjustment layer again and choose “luma matte” or “alpha matte”, so your text layer commands your adjustment layer

    I forgot to say that you find the options “luma matte” / “alpha matte” in the part of the timeline overwritten with “TrkMatte”.
    Sorry!

    I tried following the Ayota smoke tutorial but it’s too complicated to me lol. Thanks axel for your instructions. I’m using Fractal Noise as my smoke. Is there anyway to make it translucent? I want to be able to see through it to my video background.

    Mark your fractal noise layer by clicking on it
