Green Screen and iMovie in the DigiSpace
Green screen allows you to add background to your presentation. You might add a series of pictures or just one. The DigiSpace (located in Decary 051) has a green screen, a camcorder, and MacBooks available to help with your project.
When preparing to use a green screen, be sure to keep these things in mind:
- Do not a wear a green shirt. If the hue is too similar to the green screen, your background picture will be placed onto your shirt instead of being in the background.
- The green screen must be in your entire background frame.
- The green screen must be not have noticeable creases. Although it does not need to be perfectly flat, a screen that is creased or droopy will impact the final quality of your video. Also, do not move the screen while you record.
- The green screen must be placed against a solid wall to avoid the variation created by uneven lighting (such as a window).
How should you prepare for the consultants at the DigiSpace to help you make an iMovie?
- Invest a half hour or so to learn about iMovie using our tutorials (http://uneportfolio.org/help/imovie/). Many features of iMovie are easy to figure out, but have a base of understanding about the software before using it.
- Define the content of your presentation. Write and practice your presentation before you arrive to film it. Rather than relying completely on note cards, try to memorize the presentation or use the note cards only for reference.
- Whether you are presenting as part of a group or on your own, be sure to plan ahead. Practice to get a sense of the length of the presentation. Check the DigiSpace hours (http://uneportfolio.org/d-space/) and plan to meet with everyone in your group to give yourself about double the time that it will take to film your presentation. Because the lab itself is not big enough to house the green screen, your digital literacy consultant will need a few minutes to set up the equipment. Also, you will want some time to complete retakes and editing.
- Take or find your background pictures ahead of time. You may have some background pictures that you have taken or you may choose to download some stock pictures. If you are not using your own pictures, be sure to document the sources of the downloaded pictures and credit the source in a final frame of your video. When you arrive at the DigiSpace, have a plan for getting the pictures from your device to the MacBook that you will use to create your iMovie. This may be via Google Docs (you loaded your pictures into it), via a USB cable, or by another means such as a thumb drive. Please bring your own cord in case our cord is in use or is not the right type to work with your device.
- Take the video at the DigiSpace. You may use your own phone camera, the camcorder, or the Photobooth software on a MacBook to film your presentation.
- Next, make and share your iMovie.
- Create a new iMovie. Import your video and pictures into iMovie. The tutorials show this process, and our consultants are available to help.
- When editing, place the green screen video ABOVE the background pictures or video clip that will appear on the green screen area. Select the green screen video, and from the edit menu, select the overlay button (one rectangle over another) which is to the left of the color balance button (the half-filled circle). Select “Green/Blue Screen” to create an overlay of this video clip onto your background video or pictures.You might also add sound effects as a sort of audio overlay (sound effects are under the Audio menu).
- Edit your iMovie to your liking and then share it. Saving the file and then uploading to your Google Docs is one option, or you may share via youtube. Your UNE account information allows you to share in youtube without creating a separate log in. If you share in youtube, you will get a shareable link to add to your ePortfolio or to share with your audience.
Our DigiSpace consultants are ready to assist you with this process. Thanks for visiting the DigiSpace!
