This section we will cover how to create a Video using Green Screen and some of the additional options available.
Launch Photo Booth Upload and navigate to the Video tab.
Select Add Video (or double click a preexisting video to edit).
Navigate to the Video Mode section and select Green Screen. Notice when Green Screen is selected a Green Screen box appears. Click the + button to add a new Green Screen background.
In the Edit Green Screen window you should first enter a Name. Below that you'll see the option for a Background Image or Video File. Click Browse to the right of the field to find your file and import it. The supported format types include: .avi, .mp4, .wmv, .mov, .jpg, .jpeg, .png, and .bmp. Once you have imported a background, import an Overlay Image file if you want to use one. This should be a .png file with transparency.
If your background is a video file, the Duration (seconds) will already be set to the duration of your background video. If the background is a still image, you can edit the Duration (seconds) to whatever you like. This setting will reflect the duration of the final output of your video.
If you adjust the Video Speed (%), the video record duration will be longer or shorter depending on your adjustment. You can refer to where it says Your video record duration will be: X.X s for an accurate record duration.
To the right of the preview you'll noticed Key Frames. Key Frames can be used to allow the photo holder to move to various positions, change size, and rotate during your video. You'll select points in the timeline where you want the image holder to end up, set a key frame, adjust the size and positioning of the image holder, and PBU will figure out the rest!
To create a key frame, use the time line beneath the preview to choose a specific time within your video. Adjust the image holder to the position, size, and rotation you desire, then press the + button next to Key Frames to add a Key Frame. If you have multiple key frames you can select individual ones on the list to the right, and then adjust the positioning of the image holder to make changes to that key frame.
Press the play button to the left of the timeline, and you'll see the photo holder move to the defined area in the second key frame. You can add as many key frames as you like!
To further adjust the key frame settings, select a key frame and use the Opacity slider to adjust the opacity of that frame. Use the Hide box to hide the particular frame, completely. This is useful if you don't want the recorded video to appear in certain parts of your final video, or fade in or out.
To adjust the color of your image holder, use the Color Adjustment table. You'll have sliders to adjust the Contrast, Brightness, Saturation, and Hue of the entire image.
To remove the Green Screen background from your video, adjust the Chromakey settings. Use the Threshold to determine the amount of color that the program will key out. Softness effects the edges of your guest relative to the green screen. If you are having trouble keying out the Green Screen, select Pick Color, then click on the green screen preview where the saturation of the green is between the darkest and brightest visible. Once selected, try to adjust the threshold again.
Once you are finished tweaking the settings of your Green Screen Video, click OK at the bottom. Adjust any additional settings you may need to then press OK again. Make sure your video is highlighted and the Video Mode has been activated and you'll be all set to begin creating Green Screen videos!
Congratulations, you've just made a green screen video!
