This article explains how to add a fake wallpaper to a video on a Windows computer, thanks to a green screen. If you have Windows Movie Maker version 6.0 or later on a Windows 7 system, you can try using this program to perform the procedure; However, Windows Movie Maker is outdated, is no longer supported by Microsoft, and probably won't work. If you can't properly use the green screen with this application, you can use the free Shotcut alternative to accomplish the same effect.
Steps
Method 1 of 2: Use Windows Movie Maker

Step 1. Make sure you have the green screen video on your computer
If you filmed in front of a green screen, you will need to transfer the file from your camera or phone to your computer before proceeding.
It may be useful to save the file with the green screen and the one to be used as wallpaper in the same location (for example on the desktop) on your computer

Step 2. Download the file that allows the transition from the green screen
Visit the RehanFX site to get the screen transition file you will use as your green screen.

Step 3. Install the transition
Double-click on the icon of the program you just downloaded, then follow these instructions:
- Click on Yup when asked;
- Click on I accept;
- Click on Come on;
- Click again on Come on;
- Click on Install.

Step 4. Open Windows Movie Maker
Click on Start

then type windows movie maker and click on the program's film icon, which you will find at the top of the Start window.

Step 5. Import the movies
You will need two: the one you shot using the green screen and the one that has the background you want to use instead of the green screen. To import them:
- Click on File;
- Click on You open in the drop-down menu;
- Select movies;
- Click on You open in the lower right corner.

Step 6. Put both files on the timeline
Drag the movie you want to use as a background onto the timeline at the bottom of the window, then do the same with the one shot in front of the green screen. On the timeline, the background video should be before the other.

Step 7. Select the first movie
It should be the video with the background.

Step 8. Click on Transitions
You'll see this tab on the left side of the Windows Movie Maker window, right under the "Edit" heading. Select it to show all available transitions.
If you don't see this tab on the left side of the window, click Edit at the top of the window, then select the transitions.

Step 9. Click on Green Chroma 1
You'll find this item in the Transitions menu, scrolling down. Select it to add the green screen transition to the timeline.
You can also select one of the other items Green Chroma of this menu.

Step 10. Apply the transition
Drag the second video (the one with the green screen) onto the background video, then release the mouse button when you see a blue triangle appear on the timeline.
If you drag the video too far to the left, the footage will simply swap positions. In that case, press Ctrl + Z to return them to their original position and try again

Step 11. Preview the video
Click on the triangular "Play" button in the right part of the window to check if the effect has been applied correctly.
If the green screen isn't applied correctly, try using an option Green Chroma different as a transition. You can also try using Shotcut instead of Windows Movie Maker.
