Based on the provided context, the method described involves using a mobile video editing app with overlay capabilities. Here's how you can turn a video into a green screen video, explained step-by-step:
-
Prepare Your Green Screen Footage: Ensure you have a video or image with a solid green background that you want to use as your green screen. This will be the background that replaces the green.
-
Adjust the Green Screen Video Length: If necessary, adjust the length of your green screen video or image to match the duration needed for your final video. In the provided YouTube context, the person adjusted theirs to 9 seconds. This may depend on what software you are using.
-
Import Your Primary Video: Open your video editing application. The example mentions using an "overlay" feature. Most video editing apps have similar functions, if not exactly the same name. Import the video you want to place over the green screen. This will be the subject of your final video.
-
Add Video as Overlay: Look for an "Overlay" or "Picture-in-Picture (PIP)" function within your video editing app. Add your main video as an overlay.
-
Find your Video: Locate the video you want to convert.
Essentially, the video you want as your subject should be the overlay, placed above the green screen background. This is the initial setup for using the chroma key feature in the next step.
The given references don't fully explain the chroma key process, which is how the green is actually removed. This usually involves the following, which you should look for in your editing software:
-
Apply Chroma Key/Green Screen Effect: Select the main video (the overlay). Look for a "Chroma Key," "Green Screen," or "Color Key" effect option in your video editor.
-
Select the Green Color: Use the chroma key tool to select the green color in your green screen footage. The software will then make that color transparent.
-
Adjust Settings: Fine-tune the settings (tolerance, similarity, smoothness, etc.) to remove the green screen effectively without removing parts of your main video. These settings will vary depending on the quality of your green screen and the lighting.
-
Position and Scale: Adjust the position and size of your main video over the now-transparent green screen to achieve the desired composition.
-
Export: Once you're satisfied, export your video.
