Hi,
I'm new to using Fusion. I have a question about using Fusion to create an effect., I created an inverted mask where the underlying image is seen through lettering. The lettering scrolls from right to left using Keyframes. I wanted to use the same lettering and, after it's finished scrolling from right to left, zooms from far away all the way to the foreground, fully exposing the image that is my background. Can I do all of that with one node, or do I need to separate the clip and create a separate node for each animation?
Thank you

It's hard for me to visualize what you're trying to achieve, but the short version is that you probably won't be able to do this in one node, nor should you want to. The whole idea of node based compositing is to create a logical flow of operations that help you split up your tasks in manageable sections.
Actually the way you describe what you want to do helps in figuring out what to do in what order.
It sounds like you want to achieve a zoom in through the letters until the image becomes full screen yes?

Are you describing something like this?



You'll likely want to animate text. To do this, you can use your video footage and use the text as a mask to reveal the footage. However, since text first enters from off-screen, you can't simply use the footage as a background. The text needs to reveal the footage as it slides in. Therefore, you'll need a separate background for when the footage is not visible, i.e., when the text is off-screen.

You should also animate the footage's opacity, so it appears as the text appears and remains visible as the text zooms out. And probably you want to be optimizing composition for decent performance. For a bit more polish look you can activate motion blur for the text mask.

I can share my node setup, but how useful it is depends on your familiarity with Fusion so you can adapt it to your needs.
