Green screen with 2 camera angles

overtoner wrote on 2/15/2011, 11:01 AM
I'm trying to figure out if there is an easier way to do this. I film a talk show - and currently am creating the background manually for each angle in photoshop. There has to be an easier way.

You can see a few examples here:

You could to create the whole thing in 3D & use some kind of tracking+screen combination to place it. It's called a "virtual set". I'd suggest searching for tutorials on that. Odds are tutorials for AE can be adapted to Vegas with a little work.

Neither AE or Vegas does 3D, only 2.5D which precludes using them for this kind of work.
Simplest solution is dedicated virtual set systems that do this in realtime. Then you see what you get. That makes it much easier to avoid stuffups like having someone walk clean through a vitual prop.

For 2 or 3 camera angles creating a background from flat art doesn't seem like so much work - a lot less than building an entire 3-d virtual set - especially if every show is going to be a different set of backgrounds.
Of course you could build a 3-d framework with 'Panel areas' where you could change elements for each show.
Or you could do what I've done on occasion - go to the lobby of a nice hotel - during a slow time when there aren't people there - and take stills of several complementary angles with a high res camera. Then select the stills to use as your 'set' -- set focus on the camera so the backgrounds are pleasantly soft. You can blow areas up, eliminate annoying elements, or make things softer in photoshop.
Overall - one thing jumps out -- your subjects are too close to their virtual backdrop. In fact, the background is sharper than your host or guest. This should be the other way around -- soften the backgrounds as though they were out of focus (the tighter the shot the softer the background should be) and your subjects will regain their 'focal point of interest'.

Sorry .. I *must* comment on the audio.

It's nice that you have the (phony/prop) mic on the desk, in front of the host.

It is *terrible* that the real mic is so far away that you hear room echo.

Good audio is an important part of good video. See my demo on YouTube:



In this case I use dual system sound (a seperate digital audio recorder) because I cannot run cables everytime. In a studio setting you can use hard wired mics direct into the camera if you'd like.

Thanks for the heads up on the audio - that is one thing I need to work on - at least I was using an external one which is ten times better than the camera mic.

How are you able to use two mics for the one recorder?

Mic 1, channel 1, mic 2 channel 2.
In Vegas duplicate stereo audio track and make one left only and the other right only. You can add volume envelopes to each track to adjust the volume of each mic or to mute it.

ok, I noticed that there was only one mic input for the recorder mentioned in the video. can a mic go into the line in input?

Indeed, the R-09 only has a 3.5mm stereo mic input. Probably better off with a Zoom H4n which has two XLR inputs with phantom power.

You could rig up a way to feed two mics into the stereo input on the R-09 however without a fair amount of external bits you've only got unbalanced inputs with no phantom power.

Personally for that kind of gig I'd go for 4 mics fed into my Edirol R-44 so I could get the mics closer to the people talking. That's kind of pushing the cost up a fair bit though.

Each of those mics have a single 1/8" mono plug. I use this cable to combine them into a single 1/8" stereo plug.

If you had long enough cables you could plug directly into your camcorder instead of a portable recorder. Something like this might work well for you. It has a 20 ft cable. Obviously you would need two .. one for the host and one for the guest. More than one guest? You're gonna need a mixer. (or a shotgun on a boom pole with an operator that knows what they are doing)

The problem is that it is not practical to do that. When I shoot these events it is not a one-time thing. There are multiple panel/shoots during the course of the day. There is an event in one function room for one hour .. then I have to pack up and move to another room for another event. I have *limited* time (a few minutes) to set up in a new room. Even if the next event that I want to shoot is not for another hour .. there is a different panel in that room for that hour and I can't disturb them to set up. What ever I set up I have to tear down .. in a state that allows quick deployment the next time.

In addition many times panel members are late, and don't arrive until after the event has started. Other times listed panel members just don't show up. Also the number of folks on the panel can vary from one up to six. After years of doing this I have a system that works for me.
