Hi all,

Ok so here are 3 screenshots, i'll try to be as clear as possible

1_01.jpg

0_02.jpg

03.jpg

As you can see in 03 I am masking the picture so that the titles can appear behind it.

Problem is that I don't need the mask until very late in the animation, as you can see the mask is obstructing the view as shown in 02.

I can't grasp the logic of what needs to be done.

Thanks for your input

Open up the mask properties and keyframe the mask opacity so it doesn't turn on until you need it.

I think I understand what you are trying to accomplish and there are a number of ways you can do it. I used a 2 masks a subtract(mask 1) and an Add(mask 2). Mask 2 is what I believe you want your final be, while Mask 1 shows you everything until you want to see the text.

Take a look at this little example project and see if it is what you are after: 5708_maskscs5.5.aep.zip

sorry about the mask advice in the first post, brain fart here...i'm tired.

My guess is that you want 2 masks on your layer. Keep the current mask and add a new rectangular mask that encompasses the entire layer.

The easiest way to add a layer-sized rectangular mask is to double click the rectangular mask tool in the tool bar with the layer selected (make sure you don't have your current mask selected though or it will replace the mask shape).

Once you have these 2 masks you'll want to animate the mask opacity of the rectangular layer sized mask instead of the opacity of your original mask (leave that one at 100%).

Philippe

If you bring down the mask opacity to 0 %, It will not bring the opacity of the area covered in the mask to 0 % too. That what you are suffering from. This should be done in another way.

Create a white solid using Pen Tool. Then use this solid as alpha matte or alpha inert matte(as required) for the Footage and animate the Opacity of White Solid.

I should of explained it better, what Darby said was what I did in my project. Glad Darby was able to communicate the idea to you.
