  • Advice for KEYING out WATER

    Hey everyone, I’m a long-time browser, first-time poster.

    I’m in pre-prod for a shot where I’m looking to key water being splashed, with nothing else in frame, no talent or anything. The footage will be super-slow motion, either by overcranking in-camera, or with Twixtor if I can’t get the gear I want.

    My question is how to go best go about this to avoid any pitfalls, or nightmares in post. What I’ve found so far suggests to shoot on black, as green screen will bleed through, and to light from underneath. Any thoughts on this? Anyone with experience? It seems hard to believe that no black would be leftover and the complexity of the water would make rotoscoping almost impossible, and I really don’t want to go there anyways…

    Any thoughts would be much appreciated.
    Thanks,
    yb

    I agree with Dave- unless you plan to use the water shots in a black environment, far away from any other objects, it will look strange since it should pick up reflections from whatever is around. What is your final use for this water?

    Hi Dave,

    The conversation kept going over on the FCP side, sorry to double post.

    But to answer your question, it is quite fine in this instance that the water not look 100% natural, but that is a valid point for sure.
