Follow Robert through this YouTube tutorial as he demonstrates how to use our virtual sets, virtual studios, and green screen backgrounds with Sony Vegas. In this tutorial, Robert will demonstrate how to use a green screen with Sony Vegas using the chroma key feature. Should you need it, we included the transcript below for you to reference when creating and editing your own green screen and chroma key projects.
Hey this is Robert and today I am going to show you to use chroma key in Sony Vegas Studio HD 11.
First thing, open up vegas and click new where it says create a vegas project. Next, choose whatever setting you would like for your project. At this point, you will import your footage clips. Drag and drop them into the project media tab. I have imported 3 clips, a b-roll clip to be used in the studio, a green screen talent layer and our background layer which in this case is a virtual news type background layer. So, select all these clips and import them into the vegas media bin.
What I am going to do next is to setup my timeline area. Vegas default to a few different layers in the project, so I am just going to go ahead and delete this text layer since we won’t be using it. Select the text layer, right click on it and click delete track. And then I am going to come down to where there are no layers and right click and select insert video track.
If you double click on the name you can rename that layer, so we are going to call this one talent. The video overlay layer we will change to studio. The last layer we will call b-roll.
So, the next thing you want to do is to drag your clips on the correct layers. First take the talent footage and drag it onto the talent layer. next, drag the studio footage onto the studio layer. And lastly, drag the b-roll footage onto the b-roll layer.
So, you can see on the monitor that the first thing we need to do is to knock out the green background in the talent footage layer. Click the video effects tab, and scroll down to chroma keyer. There are a few different options to choose from; blue screen, green screen, etc… click the green screen chroma key effect and drag it onto your talent layer. That will open a effects properties panel where you can tweak the key to get it right. Basically, just play with the sliders until you get a good clean key from your footage. This is where having a good clean green backdrop comes into play. If you are having trouble with this step, you may want to adjust your lighting on your backdrop and re-record to get an evenly lit key behind your talent.
Now you can see that she is over the monitor in our background a bit, so we will want to position her over to the left just a bit so she isn’t right over the monitor. So, right click the talent layer and go to video event – pand and crop. If you click that, it will allow you to re-position your talent layer. If you click and drag, you can reposition the layer wherever you need in the composition. Let’s just position her in the general area that we want.
Next thing we want to do is to apply a green screen chroma key to the studio layer so we can knock out the green monitor so we can show b-roll footage in it. We’ll use the same technique as before, go to the video effects tab, chroma key, green screen, drag that onto your studio layer. Then adjust the sliders as before to get a clean key. Now, you can start to see the b-roll footage layer beneath it.
Now, the last thing that needs to be done is to scale and position the b-roll footage layer so that it shows up in the monitor at the right size and position. So the way to do that is to use the track motion option in vegas. On the timeline layer, right next to the clip name, there is a button that says track motion. Click that button, this allows you to scale and position the layer in the composition which will allow you to get the layer right where you need it. So, move your footage over to where it needs to be, then click on an edge and drag to scale the layer down. Play with it until you get it generally the size, scale and position that you need. Then click the x to get out of the track motion options.
Now you can play through your clip to see how everything comes together. And thats about it, thanks for taking the time to look at this tutorial, see you next time!
