Have a look at this incredibly-realistic ocean shoreline shader made by 3D Environment and Technical Artist Norman Staub.
Created using Blender 3.3 for a larger WIP project, the shader can hardly be distinguished from a video, thanks primarily to the extremely lifelike whitewater, which according to the creator, was set up by "extracting a Luma Matte from an overhead video of waves and then tiled by 'unfolding' the video on either side of the original texture." Additionally, the artist utilized Ian Hubert's Shakify, a free plug-in that enables you to apply real-life camera motion to any camera in Blender, to set up the camera shake for the demo.
And here's the shot shared by Norman to prove that it is indeed a shader and not a recording:
