    Hi & thanks in advance.

    I’ve created two layers, One of which is a text object, the other is a shape layer converted into a mask, so the text vertically scrolls through from top to bottom with the alpha channel selected, so you can see the text.

    What I’d like to achieve is:

    The text fading in and out at the top and bottom but with the text remaining white in the centre. In previous attempts I’ve partially achieved this by adding a gradient, which makes either the top or bottom fade out, but makes the text goes grey. ( The text needs to remain white in the centre of the vertical scrolling text)

    Any simple solutions?

    Thanks

    Simplest solution is to animate the opacity of the text layer from 0 to 100 to 0 as it moves from top to bottom.

    [alex partington] “The text fading in and out at the top and bottom”

    Pre Comp your text. Then add a mask to the precomp. Then increase the feathering on the mask.

    I say this alot Haha! After Effects has a particular render order: Source, Mask, Effect, Transformations (SMET). So when you precompose a layer, it is not like a group in photoshop. It changes the render order of your layers, turning into a source. So you need to precompose your layer and add a mask to the (newly created) precomp. However, all the “normal” animations you have already made will remain inside.

    I hope that makes sense!

    Thanks.

    In the end I exported the footage without masks, then imported into final cut pro, and applied the masks there. Less of a head ache this way 🙂

    Hope this helps somebody else out.

    Cheers
