Using a green screen is a cost-effective and easy way to transport your video anywhere imaginable, even in places that does not exist. You can sit behind a desk in a busy newsroom or dance on the moon, but first you need to know how to properly perform chroma-key compositing two videos together. Fortunately, Enlight Videoleap on iOS makes it easy.
Chroma keying is when you combine two images or videos together, compositing them together based on hues. The top layer will have sections that are "green screened" (or that another flat color will be used). Those parts, whether covering the entire background or just a small spot with a TV screen, will be replaced by what is in the lower video layer. This allows filmmakers to transport themes across very different worlds, "air" specific video content to screens, and more.
You no longer need powerful desktop editing software to combine green-screen footage with your background material. Your iPhone is more than enough to do the job. And Videoleap's chrome button feature allows you to merge two pictures or videos in seconds. You can use your own green screen and background material, or you can play around the Videoleap of the stick video clip to test it
:. In Green Screen + Background Video
First, before you go any further, make sure you've updated "Enleap Videoleap Video Editor" on your iPhone. Then open it, and start by finding both a green screen video, and a video you want to play in the background.
We'll show you three different ways to add the two videos together in your Videoleap project. For method 1, we will add the background video first, then the green screen video, while in method 2, we will add the green screen video first, then the background video. In Method 3, we will add them both separately then combine them.
All of these methods will work, but the second and third will format the background video to the size of the green screen video automatically (if the same aspect ratio.) If you change the size of the
In the timeline, tap the red-and-white plus sign, and find a video that you want to be in the background of your green-screen video want, what does it mean, instead of the green screen appears. You can use Videoleap and others to provide your "Camera Roll" or one of the albs in your Photos app, in your Files app or through stock footage (some is not free).
After you add a video to the search by tap in the timeline in the bottom left of the toolbar on "Mixer". Well, either download a green screen video from your albums or find a free green screen video from the storage area. After you tap it, the green-screen video will already be placed over the video in a project, starting at where the playhead is.
This is similar to Method 1, but after you tap the red-and-white Plus characters In the Timeline, you first select a Green Screen video. Then tap the green screen clip in the timeline to highlight it, then scroll at the bottom of the toolbar and tap Mixer. Your green-screen clip will shrink to the top layer in the timeline. Next, tap the red and white plus sign button that appears below the green screen layer, then find and select the background video you want. Regardless of where it was placed the playhead, the background in the timeline will appear at the same time as the green screen clip start.
The third way is pretty simple. Just tap the red-know plus sign in the timeline, then select either your green-screen video or your background video. Once it's on the timeline, tap the red-and-white plus sign again to add the other video.
Once they are both on the same level in the timeline, tap-and-hold on the green screen clip in the timeline until the clip becomes a small box, then pull it up a little bit until it's the top one Layer and the place it will be an upside down teardrop up the video, then pull over it opens you composite want to let it go with it.  Step 2: Replace the Green with the Background Video
Now that your two videos overlap in the timeline, make sure that the top green screen layer is highlighted (if you use Method 1 or Method 3 used above, it will already be highlighted), then tap on "Chroma" in the toolbar.
The color "picker" tool will be selected, and you will need to tap and hold on the circle icon in the video, then move until the crosshair is in the green screen area. The green screen area will disappear immediately, replaced with the background video
You have two tools to work on the composite. "Spread" "Threshold" and use "Threshold", which is preset to 25, to refine the edges of the object (s) from the green image video; Increase it to refine the objects. By default, use "Spread," which is 0 to configure the opacity of objects on the screen; If you increase the value too much, the green area will be displayed. If you are not satisfied with the green screen results, you can use "Reset" to start over.
Once you're done, tap the gray area in the timeline or the back button on the toolbar to quit the chroma key tool. Then you can tap on the green screen video clip to edit the size and placement of the foreground, if necessary. As soon as the red lines appear around the video, pinch it down or zoom in to pinch it, and pull it on where you need it.
If You do not need to make any further adjustments (see step 3), tap on the action (aka Share) icon in the top right of the "Save" button to download it to your device. You can adjust the resolution and the images per second beforehand. The following is the final result of both the above mixed together videos
Step 3:. Adjust the Layers in the Timeline
If you're happy with how it looks your green screen clip, it's time to make further adjustments if necessary. To move it to a later part of the background video, just tap and hold the center of the green screen layer in the timeline, then drag it to the desired position.
To shorten the green-screen clip, tap and hold one end of the layer and drag it to the desired location. And either the green screen or the background layer, tap and hold on it to delete, then slide it to the garbage down icon that appears.
If you use Brightness, Contrast, Saturation, Exposure, and other aspects of either the green screen layer or background layer over time, use the "keyframe" tool (the diamond icon with a plus sign, that appears on the right side above the toolbar) to create animations in specific sections of the video. You can use it to add fade ins and fade outs, too, but there are special tools for those in the "Animation" section.
