This is a quick walk-through of how to use the Green Screen app by Do Ink. We are going to start by clicking on the app:
Next we begin a new project by clicking on the "+" in the upper right hand corner.
This brings you to the compose window. The layers are at the bottom of the screen. You want to make sure your Camera with the green screen is in the top layer, so when you use the chroma filter to look through the layer you see the images UNDER it.
Click the plus and add a camera, image or video. You can use video pre-shot on a green screen also.
In this picture you can see that the chroma filter is on and that is why the green screen is black in the main window and green in the preview window. It is black because I have turned on the chroma filter without anything under it. So the black you are seeing in the picture is actually the very fabric of the universe.
Now with the image selected you can see the image of Wokka in the preview window. When we select the video layer you can see the green screen in the preview window and the active green screen effect in the live view window.
You can program and time the backgrounds just by using the timeline. Here I have dropped in an illustration of a native America at about 6 seconds.
