HELP - Line animation

Hi everyone!

I'm brand new to DaVinci Resolve and animation overall, only been doing it a bit in photoshop before. I'm mainly a photographer and still image content creator that now needs to do a bit of animation.

I've been spending the last 2 days watching tutorials and trying to create what I need but not much success.

Next week I'm building a led-screen where I want a small line to "travel" on the outside of the black blocks. The line should always be visible but sort of pulsating and traveling around and around and around. Look at this video in the background on the lines:

(time 9:40 if it bugs out)

Could someone please help me understand how I create this animation and look?

Thanks!

You can try using a Background node and Paint node to create the effect.

I'm going to post some code down below. Just highlight and copy the code, then in the Node Editor area of Fusion paste the code, it should create several nodes. This should give you some help in what you are trying to accomplish. The repeating effect is created by using the Spline Editor.

Code: Select all
