Lay the plywood out flat on the ground. Use the metal braces to join together as many pieces together to form the entire backdrop. Use the small screws and the drill to complete the brace fastening.
Place a flat brace at the top, bottom and middle of each seam to make it as secure as possible.
Flip the connected pieces over so the smooth side without the braces faces upward.
Paint your entire backdrop in the design you are looking to film. This can look like a plain wall or the outside of buildings --- whatever setting you are creating.
Dry the boards overnight. You want to make sure the paint is completely set before you work on the other side again.
Flip the boards back over so the painted side faces the ground.
Cut the two-by-four boards so each board is one-third the height of the wall when it stands up. Make sure you have enough boards for two boards to be placed every 1 1/2 to 2 feet apart.
Connect the two-by-fours in an L-shape using the L-brackets and screws to securely fasten the pieces together.
Measure the distance between the two boards fastened together about a third of the way from the edge of both sides. This completes a triangle shape and will add support.
Cut more two-by-fours with the circular saw to the length you measured. Fasten this board to the L-shapes to complete the triangle. Fasten the boards together with screws and the drill. This offers a strong support for your board.
Fasten the L-shaped boards to the back of the painted plywood so the bottom board is flush with the bottom of the plywood.
Stand the board up so it stands on the L-shaped boards. Your backdrop is complete.
Set up a shower rod in the room you wish to film. You can attach it to the wall with hooks or on a clothing rack.
Put gliding hooks through the green material on one side. Keep the hooks 1 inch to 1 1/2 inches apart to keep the screen from rippling once it is set up.
Slide the screen onto the shower rod. This will be what you film in front of, so you can insert the background later.
Film a static loop of the background you want to "key" into your green screen shot. If it is a moving background, make sure you take a rather long video. If you are using a static shot, take a simple digital still image.
Lay the new background into the green screen video and adjust as necessary.
