I feel like i'm very close, yet i can't obtain what i am after. I am trying to do a liquid wipe over a picture, but i want it to somehow be content aware. I am using roughen edges over the liquid mask, so the wipe looks pretty good. But it is under no circumstances content aware. I would love if i could make it hang on a bit more over some details of the image. Anyone has any ideas on how to obtain that? I could even create some masks over the picture if there is any alpha channel method.
You might try dropping a CC Glass effect on your liquid, and then setting your footage as the bump map. Play with the "height" and "displacement" settings to make your water pool around the details in your image.
You might even want to duplicate your source footage and create a higher-contrast version to bring out the details. Turn it off in-comp, but use it as your bump map. Make sure to precompose the contrast adjustments with the footage - CC Glass will not see any adjustments placed directly on the layer.
