Green Screen

In this exercise, you will create and edit a movie in Clipchamp, including using green screen video and importing audio to overlay your clip. If you have any questions or get stuck as you work through this, please ask your instructor for assistance. Have fun!

  1. If you don’t have a green screen video that you want to edit, let’s start by downloading the audio and video files below and save them to your desktop:
  2. Open Clipchamp.

  3. Next click on the “Import Media”. importing media icon
    • Click on the “Desktop” on the left navigation pane and then hold down the “Command” key and select the “chickens.mp4” file, “tropical-fish.mp4” file, and the “ocean-waves.mp3” file.
    • Finally, click on the blue “open” button on the bottom right of the dialogue box.
  4. Add the video clips and audio clip to the timeline (see pic below for example, it is important that the Green Screen Video is on the top of the timeline):
    • Drag the “tropical-fish.mp4” video clip you just imported into the timeline at the bottom of the iMovie screen.
    • Next, drag the “green screen chickens” video on top of your background video.
    • Lastly, drag the “ocean waves” audio below your background video clip.
  1. Let’s make the green screen magic happen! Green blue screem and video overlay dropdown
    • First, select the green screen clip in the timeline with the chicken.
    • Next click on the “Effects” button just above the video preview window in the top right of the program.
    • Then click on the “Green Screen
    • Your chickens should be standing on the coral under the ocean now when you preview the video!
  2. Trim and modify audio levels in video and audio clips: audio under tropical fish
    • Let’s trim the audio clip by selecting the audio clip and then grabbing the side handle on the right of the clip and dragging it even with the video clips.
    • There is no audio in the green screen video clip, so we don’t have to worry about it.
    • There is audio in the tropical fish video, so we will mute that audio by selecting the tropical fish video clip, and then right clicking, selecting audio and muting the clip.
    • If you want to make the background ocean waves audio louder or softer, simply select the audio track, select audio (on the right hand side bar) and move it up or down.
  3. Let’s add a title to the video by selecting the “Text” tab in the left hand side window, and the drag and drop one of the titles at the beginning of the timeline.
    • In the video preview window double click to edit the title text.
  4. Now add credits for your video by dragging and dropping a credit style “title” from under the “Titles” tab to the end of the video. Edit this same way you edited the title in step #7.

  5. Once you’re happy with your edited video you’ll need to export it in order to upload it to YouTube, or share it via Google Photos or some other sharing service:
    • Click “Export ”in the top right of the Clipchamp window.
    • Select whichever quality you want from the drop-down menu (higher quality results in larger files).
    • Next, select where the file will be saved and give it a memorable name.
