How to Use Greenscreen on Windows Movie Maker

Using Shotcut

1. Check your computer's bit number. In order to download Shotcut, you need to know whether your computer uses a 32-bit system or a 64-bit system.

2. Download and install Shotcut. Go to https://www.shotcut.org/download/ in your browser, click the "installer" link for your computer's bit number, and then do the following once the file finishes downloading:

   1. Double-click the Shotcut setup file.
   2. Click Yes if prompted.
   3. Click I agree
   4. Click Next
   5. Click Install
   6. Click Close

3. Open Shotcut. Open Start

   , type in shotcut, and click the teal Shotcut icon at the top of the Start window.

4. Click both the Playlist tab and the Timeline tab. Both of these options are at the top of the Shotcut window. Doing this adds a "Timeline" section at the bottom of the window and a "Playlist" section on the left side of the window.

5. Add files to Shotcut. Click Open File in the upper-left side of the Shotcut window, then select the files that you want to add to Shotcut and click Open.

   1. You should have at least two files: the green screen video, and the background video or image that you want to use to replace the green screen.

6. Create two video channels. Click ≡ in the upper-left side of the Timeline section that's at the bottom of the window, click Add video track, then repeat this process once more.

7. Insert your video in the first channel. Click and drag your green screen video from the "Playlist" window onto the top video channel, then release it.

8. Add your background to the second channel. Click and drag the background video or image onto the second channel, then release it.

   1. If you're using a background video, the video should be the same length as your green screen video.
   2. If you're using a background image, you'll need to click and drag the image's left or right edge to extend it to be the length of the video.

9. Select the green screen video. It should be at the top of the "Timeline" section.

10. Click the Filters tab. This option is at the top of the window. A "Filters" menu will appear in the "Playlists" section.

11. Click ＋. You'll find this below the "Filters" menu in the "Playlists" section. Doing so will open a list of filters in the "Playlist" section on the left side of the window.

12. Click the "Video" icon. It's a computer monitor-shaped icon below the "Playlist" window.

13. Click Chromakey (Simple). You'll find this in the middle of the "Playlist" window. Doing so opens the green screen settings.

14. Adjust the green screen distance. Click and drag the "Distance" slider to the right until your green screen replacement image or video appears on the right side of the window.

    1. As a general rule, you want to avoid moving this slider over to the "100%" mark.

15. Preview your movie. Click the "Play" triangle below the movie window on the right side of the window, then adjust your green screen as needed. If you can see a large amount of the green screen, drag the "Distance" slider to the right; if you can't see enough of the background, drag the slider left.

16. Export your movie. Click File, click Export Video..., click Export File at the bottom of the menu, and type name.mp4 into the "File name" text field. Click Save when you're done to begin exporting the file.

    1. Replace "name" with whatever you want to name your video.
    2. Exporting may take several minutes to several hours based on the video's size and resolution.
