Apple Motion: Creating 2D wave texture

Update:

I have been looking at tutorials and I think I might have found something useful:

I think I might be able to combine this "liquid" effect with my cloud generator... or perhaps use the ink bleed stroke?

I have progress but if I cannot get an opacity gradient and more weight at the front and less at the bottom, I might have to restart.

Your original response to my post where you animated my reference image is pretty good and I need something just like that. But, I'm animated a moving texture from "above" if you were looking down at the ocean. So, I need to create it from scratch out of shapes.

It's kind of close, but I have my own method that I really like. It's just that I cannot figure out how to refine these details. I wonder if I could use a gradient and a bump map to put on the wave and make the top bigger and the bottom smaller?

I think I figured out a really easy answer. If I duplicate the replicator and make the spread lower, adjust the scale a little bit, I can create one simple "line" of connected water. Then I can make the original replicator even in its scaling.

I was not thinking of touching Final Cut because this is an image asset for a 3D model. However, I guess I can still play around with it? Unfortunately, I cannot find alpha handling anywhere. I am just dragging in the mov into Final Cut.

I actually figured it out right after I sent that, sorry. This is for an iOS game. My issue is that I cannot get it to work outside of Final Cut, despite my alpha type being set to premultiplied. This is very odd and random, but I tested a random animation in an app called Calipeg for iPad and exported a circle (one frame) as HEVC with alpha (that was really the only configuration option) and it seemed like the outline was basically not there? Perhaps I was tricking myself but it looked like it wasn't there anymore. I am baffled by what is happening. Anything I could do perhaps in Compressor? This is just weird. It's the same file type.

Ok. So I figured out a little bit more information. It seems that the background color of my scene impacts the outline color of the animation. I guess I'll set it to white if all else fails. Super odd. Any final ideas on weirdness with edges and transparency to prevent this? The only thing I could guess is that the edge is the area where that happens because it's semi transparent? Transparent videos is not my area of expertise so I am certainly learning as I go.

I found a replicator that pretty much describes the type of behavior of a wave. I don't know if that is useful?

I updated my other reply.
