I think the subject captures all the macro elements of something i'm working on, but here's the story...I need to comp a GS sequence of a woman falling backwards into a cobblestone street which, when she hits it, turns into a liquid surface with ripples and the whole nine yards.
Practical is that we're shooting her falling into a shallow pool we built with GS all over and under...(ps, this is not a complete pro production, but we're doing our best to learn as much as we can). I will grab a matched plate of the cobblestone ground to comp behind.
I've alrady began noodling aroudn with some ideas on how to make the street exhibit water like behavior as the talent 'hits' it, but i would absolutely love some thoughts or suggestions, if anybody has a few minutes.
Tools at hand BTW are, MAX 7.5, C4, Turbotoolkit suite, and dvmatte pro.

Right off hand, you could use a displacement filter on the cobblestone driven by the water layer, but you may want to shoot the water layer clean too (just dropping something heavy into it to create waves). I've done this with some text over a shot of pool water to make it distort the text, but what you are attempting to do is much more complicated. This may get you started in a direction, but hopefully someone will post with more compositing experience and some more detailed help.
Here's a link to an indy film trailer where I used that displacement filter on some text so you can see what I'm talking about:

that's a good idea, hadn't considered that. I think we may have some trouble considering the setup we built is quite literally a one time deal, once anything large falls into it, its pretty much going to begin draining, BUT a good idea nonetheless, i'm going to see if we can somewhow finagle that in.

Hmmm... before you do that, do you already have the footage of the woman falling into the water? If so, then I would experiment with the displacement filter with what you have and see if you get it to work. I was originally thinking that having the woman in the water that you are using to drive the displacement might be problematic, and it still might, but I was just thinking that since you are going to add her anyways... Maybe it would work better with her actually falling into the water. I'm sorry, man... I know I'm going back and forth here... If the woman in water clip doesn't work then maybe try shooting the water "clean". Good luck, and post back with how it works out.
I still hope someone more experienced can lend some advice to ya.

i'd also get a clean plate of the woman falling onto like a matress or something that you can repeat to get just right. hopefully on a greenscreen if possible.
