Green Screen Fun: Where Do You Want To Be?

Our TV studio's "green screen" walls have been in demand this semester. Already this semester, three or four students and student organizations have booked time for various video and still photography projects.

So this got me thinking that my Electronic Media Production II students should be exposed to the capabilities of green screen or chroma key technology, as it's also called. What this allows us to do is superimpose a background to the photo or video shots against a solid green backdrop. Blue also works.

Here are a couple before and after examples. I processed in Adobe Premiere Elements, which we have in our Dell and student computer labs in Crawford.

I used PhotoShop in the second image to crop the black border.
Here's another version of the Running of the Bulls in Pamplona, Spain. This one has some action of me running! Thanks to my students Stephen and Marcos for taking a few shots of me against the studio green screen.  One tip, it would look better if I was shot from farther back so I would be smaller in the action shot.

In the shot below, I had the camera back several feet from the above one, when taking the photo of me against the Green Screen. I may have been too close to the wall in the one below. Some green is bleeding over on the outline of my shirt. 

In Adobe Premiere Elements, here are the steps to take your green screen image/video and put it against the desired background:

For still shots, the final step, missing from the above, is to hit the camera icon to save as a still shot the image the cursor is on in Adobe Premiere Pro.It will be saved as a bmp file format, which can be uploaded or inserted to your Blogger post. 

Here is a screen capture of where the two shots should go. Your green screen background shot goes in Video 2 and your background image in Video 1. 

o remove the Green Screen effect, right click on taffected clip, go to Remove Effects (note: you must have that clip highlighted or clicked on for this step to work)
