Matchmoving a shot with rain
Posted in: Beginners TalkHi there. Haven’t been here in a while. I don’t think this is a beginner question but the professional and VFX supervisor forums are now private (how do you re-gain access to them?) so I guess there were some changes around here.
Anyways, on to the question. 🙂
We have a green screen shot where there needs to be rain. It can’t be digital rain because there’s an actor standing in the rain and the camera gets pretty close to him(close up) so you will see he is not wet and we need to see the water hitting him and bouncing of him and the drops etc. So it needs to be real water. The problem is it also needs to be a dolly shot, which will naturally need to be matchmoved and for that we need tracking marks. Tracking marks not only on the green screen but also in different depths and along the dolly path etc as you know. In a normal shot you just roto the tracks out when keying. But here you would also be rotoscoping the rain out leaving rainless holes in the image.
Question is, would adding digital rain on top mask the problem or would it still be visible? If a plate of digital rain to fill the the holes won’t work, what is the solution? Having tracking marks that can be keyed so they don’t need to be rotoscoped? If so it will make it all much harder as we normally use light stands and other things with cross stickers to them when we need depth marks for matchmoving shots.
Also, would the rain drops confuse the matchmove software making tracking a nightmare? Never done that type of shot before.
