Welcome to Green Screen by Do Ink! This brief tutorial will show you how to make a simple Green Screen project and save a video to your Photo Library.
Let’s start by creating a new project.
Your new project is automatically opened in the editor.
At the bottom of the editor is the timeline: three gray stripes stacked one on top of another. Each of the stripes represents a layer. Let’s add a photo to the bottom layer:
The photo is displayed in the canvas area above the timeline, and thumbnail images have been placed on the timeline.
On iPhones, the chooser is closed automatically after adding an element to the timeline.
Next, let’s add a video to the timeline’s middle layer.
If you’re using an iPhone, tap
on the timeline to open the chooser again, then tap Tutorial Assets at the top of the chooser.
Now, the video is displayed in the canvas area, with thumbnail images on the middle layer of the timeline. Notice that the green background in the video is gone! We’ll talk about that a bit more soon.
Before using most the app’s tools, you’ll need to select an element for the tools to work on. Let’s take a minute to learn how to do that.
You can select an element either by tapping it on the timeline or on the canvas.
If you tap an element on the timeline that’s already selected, a small tool panel will appear under the timeline. You can hide the panel by tapping the same element on the timeline again.
The video on the middle layer was shot in front of a green screen. Why isn’t the green background visible on the canvas? It has been hidden by the chroma tool.
The chroma tool makes regions of an image that are a specific color transparent. The tool is enabled with a green color by default for images on the upper and middle layers of the timeline.
The rest of this section will teach you a bit more about using the chroma tool. It’s optional, so feel free to skip ahead to Step 6.
The video should already be selected, with a yellow border around it on the timeline. If necessary, tap the video on the timeline or the canvas to select it.
Tap the button on the toolbar above the timeline to open the chroma tool.
Disable the chroma tool by turning off the “Enabled” switch. Notice that the green background if no longer transparent.
Turn the “Enabled” switch back on. The green background becomes transparent again!
If desired, use the “Chroma Key” control to select a different color, and use the “Sensitivity” slider to fine-tune the results.
Tap the “Done” button in the upper right corner to return to the editor.
You can also move and resize elements on the canvas. Let’s see how that works.
The video on the middle layer should still be selected. If not, select it by tapping on the timeline or the canvas.
Notice how the two elements have different lengths on the timeline? Let’s fix that now.
There are two different ways to use the timeline: 1) scroll to a particular point in time by simply dragging left or right, and 2) move or trim an individual element on the timeline by touching and holding down for a moment and then dragging the element to a new position.
Tap the photo on the bottom layer of the timeline to select it.
Notice that the selected element has a yellow border around it, with a green box at the left end and a red box at the right end.
You’re all done making your project! Now, let’s export a video to your Photo Library.
If desired, you can preview your project first by tapping the
button.
You’ll see a progress bar at the bottom of the screen while the app converts your project into a video. When the video is ready, the Video Preview view opens automatically.
The Preview Video view lets you view and export your finished video.
If desired, tap the
button to preview your video, or scrub through it using the slider control.
Congratulations on finishing your first Green Screen project!
You’ve learned the basics, but there is so much more. For example, the chroma tool isn’t the only way to make portions of an element transparent. You’ll want to learn about the crop and mask tools too. Check out the documentation and the other tutorials by tapping on the button in the Gallery.
And have fun making your own Green Screen videos!
