<p>You can make an image move like water by using a displacement map. This will warp the image as if the folds in the surface of the water are refracting the light as it passes through.  For better results, you'd also want a separate map for reflection and/or specularity on top of the water surface.  Here's an example in Blackmagic Fusion.  If you copy the code text here, and paste it into the Node graph of fusion, it'll show up as a working composition.  <a href="https://youtu.be/ZkKyrp0gp-Q" rel="nofollow noreferrer">Here's what the result looks like.</a>  Of course, you'll need to supply your own footage, but you can examine this setup to see how it works.</p>

Welcome! Water won't give you a clean key. You need the color of your background to be pretty uniform and water scatters light and rarely looks a single color, especially if moving. Also, when keyed out, the background is gone and replaced with the key signal, so if you even get a clean key, the movement of the water won't transform your key signal to map on to the peaks and valleys of the water. It will just be the flat key signal. I'm not a motion graphics expert, so I can't point you to a specific plugin, but After Effects is likely the way to go.

to make an image move like water, you want to "displace" the image.  I'm not sure what the AE effect for this is called, but in Blackmagic Fusion (free), it's called displace and uses a luminance field as input.  The caustic light pattern that you see at the bottom of a swimming pool would probably work well.  There's other ways to use "normal maps" which use RGB values, instead of just B&W luminance, but generating them is more complicated, and they don't resemble anything in the natural world, so you cant just go out and film them.
