Rob Aitken Posted October 6, 2010 Share Posted October 6, 2010 (edited) I'm a student looking for some help with a particular shot in one of our projects it basically goes like this.... 15. MFS Circle-Dolly , Front Of Subject to Back Of Subject. John rips into the main chords into the song. As we dolly around to his backside, his bedroom wall turns into a full blown concert at a large venue. SO... my question is how do I film a subject with a greenscreen background if there is going to be a circle dolly? Is there an easier way to do this than green screen? My plan so far is to somehow rig a green screen opposite the camera on another circle dolly and the background would move as the camera moved, then simply replace the greenscreen with a circle dolly shot of the bedroom and fade it to a circle dolly shot of the concert. Shooting format is RED Please any advice is helpful Thanks! Edited October 6, 2010 by Rob Aitken Link to comment Share on other sites More sharing options...
Premium Member Brad Grimmett Posted October 6, 2010 Premium Member Share Posted October 6, 2010 My plan so far is to somehow rig a green screen opposite the camera on another circle dolly and the background would move as the camera moved, then simply replace the greenscreen with a circle dolly shot of the bedroom and fade it to a circle dolly shot of the concert. That could work but moving the green screen opposite the camera probably won't be as easy as it sounds. Your other option is to just get enough green screen so that it covers the whole area you need it to and you don't have to move it. You can still fade the two shots together.

Dirk Naves Posted November 1, 2010 Share Posted November 1, 2010 depending on your lighting scheme and how much of a perfectionist you are, you might want to consider rotating your talent rather than your camera. that way, you can just set up the greenscreen opposite your talent, and when he rotates on the spot, the illusion will be that the camera is rotating around him. this won't work with a full-body shot. nor will the lighting be perfect (unless you rotate that too). this is not the ideal way to get the shot, but it is a possible and very cost-efficient way to get close to it. just an option to keep in mind.

David McDonald Posted December 1, 2010 Share Posted December 1, 2010 Rotating would definitely cause lighting problems. I think your best option is to just get enough green screen to go all the way around. You could try moving the green screen as the dolly moves but that might require another dolly or some kind of crazy rig that you probably don't have access to. You will need markers to go on the screen and someone who is capable of 3D tracking and making 3D backgrounds to blend together....or you have to shoot really good plates of a bedroom and concert that will blend together.

Markus Rave Posted December 1, 2010 Share Posted December 1, 2010 I second rotating the talent. Put your lights on a dimmerboard and change values while rotating. You will be lighting the background separately anyway so I don´t see lighting problems. With a 360° green you would need a huge area and that just to keep lighting simple. Can´t see any benefit there. Link to comment Share on other sites More sharing options...
Ian Blewitt Posted December 14, 2010 Share Posted December 14, 2010 Be sure to shoot your background plates first, that's the most important thing when chromakeying, then light your green screen footage to match. Personally I think depending on what your talent is wearing it might be easier to just do a full circle in the bedroom and rotoscope him out and add the background. Then you won't have any gear in the shot either. Is the shot a medium or close up, or a full body? I can offer some more suggestions too if you let us know what kind of shot it's gonna be.

Jim Menkol Posted December 30, 2010 Share Posted December 30, 2010 Basically you have two ways if you don't have an entirely green room. Rotate the talent, which gives you some lighting problems (as has been stated), or rotoscope (which can be a pain). IMHO roto will be your best bet, if you think you have the time in post (it doesn't take that long, but I don't know if you're really pressed). Shoot the talent in the bedroom with the circle dolly and roto from there. Or shoot in the studio with the green screen so you only have to roto half the shot, but even that will give you some lighting issues to be had with any chromakeying.

Nishant Joshi Posted January 5, 2011 Share Posted January 5, 2011 You could try putting the green screen on one side of the bedroom. Start with your camera facing your talent who would be in a bedroom backdrop. Dolly around and have the camera face the green screen. Link to comment Share on other sites More sharing options...
