How to Make and Use a Green Screen Easily
Matrix and Lord of the Rings trilogies or the latest sequel of the Avengers have something in common. None of these movies could have been filmed thirty years ago because the Green Screen technique wasn't as advanced as it is today. The phantasmagorical landscapes, dragons spitting fire or wizards casting spells are just a glimpse of what can be accomplished by using a Green Screen in a movie studio. The advancement of digital technology has made this cinematic technique much more accessible to filmmakers and using it in your own video doesn't mean that you have to have multimillion production budgets.
All you need to create mind-boggling visual effects that will leave viewers speechless is a piece of green cloth and a camera that can capture high-quality video. Let's dive deeper into the magical world of Green Screen filmmaking and discover how you can use it in your own videos, even if you are working on a low-budget film.

Part 1: What is Green Screen?
The term Green Screen or Chroma Key is self-descriptive because the technique features an actor against a green or blue background. Naturally, you may wonder why does the screen have to be green or blue? The reason is that these two colors are considered to be the furthest away from the natural skin color, which enables the editors to replace the background without the danger of damaging the human figure on the screen.
Histoty of green screen: The Blue Screen technique originates from the early 1930's and since then it has been used in countless films that have won Oscars for special effects, including George Lucas' 'The Empire Strikes Back'. Green Screen is a technique much more recent that has become popular in the age of films shot on digital cameras. The basic concept of the technique is rather simple, place an actor against a monochrome background and film all the on-screen movement, dialogues or any other scenic action and then replace the background with landscapes, digitally generated cityscapes or futuristic interiors by using visual effects that every professional video editing software features.
Equipment to shoot green screen: To make the green screen work well, using a good quality camera that shoots HD quality video is advised. However, any camera that shoots videos in MP4 and MOV formats will work, including phone cameras. You will also need a good quality Chroma key software, many are available on the market and some can even be downloaded for free. Some software include Windows Movie Maker 2.0, Movavi and Final Cut. However, consumer grade software have lower grade Chroma key effects. For still photographs, Adobe Photoshop has a built in Chroma key feature that allows users to manipulate photographs taken with a green background by changing it to whatever they would like. Many software comes with Chroma key backgrounds, others can be downloaded separately.

Method 1: How to DIY A Green Screen Effect Video
Despite what you may think, you don't have to be Peter Jackson or one of the Harry Potter directors to be able to use the Green Screen technique in your film. As a matter of fact, all you need is a camera that can shoot high-quality video, a tripod and a piece of green sheet you will be using as a background.
Step 1: Setup
Setting up the location for filming the Green Screen scenes is not very difficult, but before you start arranging your equipment, you must first decide whether you want to shoot the scene in a studio or on an exterior location in broad daylight.
Shooting outside can be an excellent choice if you don't have spotlights because the sunlight can be used to light the scene perfectly. However, using spotlights in a controlled environment will probably give you more creative freedom, because you won't have to worry about shadows or sudden light changes.
Step 2: Positioning the Green Screen
This may seem like an easy step, but failing to clear the green sheet of wrinkles may cause a fair amount of trouble in the post-production. Make sure that the piece of sheet you are using as your background is perfectly smooth because even the tiniest wrinkle will be visible once you remove the background in a video editing software.
Step 3: Clothes
The costume your actors will be wearing in front of a Green Screen shouldn't be green, because the editing software will remove all green parts of the shot including the green parts of the costume. In order to avoid dealing with these problems, choose the colors that are in contrast with the green or blue background so you don't have to reshoot the scenes. If you would like to make your actor transparent using clothes that have similar tones as the background is completely justified.
Step 4: Shooting the Green Screen scene
Once you've chosen the location, adjusted the lights, selected the right colors for the costume you are ready to begin filming. Make sure that your camera is perfectly still by placing it on a tripod to avoid camera shakes. Let the actors perform the scene and try to pay close attention to each and every detail in the shot because it will allow you to achieve better results.

Method 2: Download green screen backgrounds from website
The fastest way to get a Green Screen you can use in your video is to download it from a website, such as VideoBlocks or Shutterstock . You can obtain hundreds of different video files that feature many different kinds of movement and elements that can be used for the creation of your videos. The advantage of using pre-existing Chroma Key footage is that you don't have to go through the trouble of filming the footage yourself, which can be a daunting task if you don't complete all the steps of creating the Green Screen footage correctly.
However, downloading the footage from of the photo or video stock websites isn't free and it can prove to be quite expensive. Furthermore, the duration of the videos you can download is often limited to just five or ten seconds.
Green Screen videos that are available for download will help you save time in the post-production, but they aren't a reliable option for filmmakers who would like to create unique visual material or if the Green Screen scenes last more than just a few seconds.
As we can see from the above video, apart from downloading green screen footage from website or shooting green screen footage by yourself, you can also use the specially designed video effects in Filmstocks, which allows you to make a big movie within few minutes.

Part 3: How to composite a video using a Green Screen
Once, the filming is over you can start thinking which video editing software you should use to edit your video. Wondershare Filmora is a reliable video editor that can be used to create a video that features Green Screen scenes. Layering scenes in Filmora is an easy process that can be completed in just a few simple steps.
1. Import the footage into the Filmora9 video editor
If you already have Filmora installed on your computer, start the program and head to Full Feature Mode and then proceed to import the background videos and Green Screen footage to the media library. Drag and drop the Green Screen video clip to the editor's PiP track and position the cursor over the clip and right-click on it. From the menu that emerges select the Green Screen option or double-click on the Green Screen clip to access the settings.
2. Adjusting the Green Screen Settings
After the Motion settings window is displayed on the screen, click on the Advanced tab and wait for the new window to appear on the screen. Select the Effects tab and click on the 'Make parts of this video transparent' checkbox. From there you can select the color you want to be transparent (make sure it is green if you are looking to create the Green Screen effect) and adjust the levels of transparency, shadows, and borders. The flip option that enables you to rotate the clip is also available.
3. Positioning the background clip
The final step of the process is to position the background video clip on the video track on the timeline. The background footage will fill the transparent part of the Green Screen clip, and the two videos will appear as one coherent video. Resize the Green Screen clip to adjust the size of the figure to the background by scaling it down on the preview window. Your Green Screen video is now ready to be exported.
