Green Screen Technology is an important milestone in the history of graphic editing. It enables you to change the background and add other visual effects to your focused visuals. The video is filmed in a green background and is replaced by a different chosen background, real or created, by the green screening.
Alight Motion is capable of carrying out green screen editing. If you have a video or a picture with you, you can remove the green background and replace it with a desired one. Therefore, your videos can be made global and limitless, regardless of the place they were filmed in.
Preparing Your Green Screen Footage
There are few things that you should keep in mind when filming your original video to edit in green screen:
It is important to use a solid, wrinkle-free green background for filming which will give you optimal results. The wrinkles can interrupt accurate detection of the green screen which will be a problem when removing it. So a plain and clear screen you place will be the best way to ensure clarity.
Proper lighting setup is required to ensure even green color and avoid shadows. When the green color is changing from place to place and when the shadows are present, it is again difficult to replace the background.
Your green screen footage can be improved by using shooting tips, like maintaining distance from the background and avoiding reflective clothing. Reflective clothing can create visual problems with the lights you use around. The distance is again a matter of clarity and resolution. Therefore, by maintaining such factors in line, you can get the best footage for your editing.
The Power of Chroma Keying in Alight Motion
Alight Motion uses the concept of Chroma Keying to perform green screen edits. Chroma Keying is selecting all the pixels of a similar color specified by the designer and removing them. The pixels need to be in the same layer of the footage as well. This makes that particular background transparent.
You can perform Chroma Keying to apply green screen in Alight Motion by following the below given steps:
- First select the green screen video clip from your device.
- Access the “Effects” panel in Alight Motion and choose the “Chroma Key” option.
- Adjust the “Color Picker” to select the green color precisely. You can do this in one go if your background is flawless.
- Refine the effect using parameters like “Tolerance” and “Feather” for clean edges. This has to be done carefully because if not, the background replacement can be identified by viewers. Therefore, make sure that the edges are well feathered and that the temperature and contrast of the full picture remain unique.
Creating Engaging Compositions
- After you complete the Chroma Keying successfully, you need to perform composting. Composting is the technique that is used to combine the visuals of 2 images into one. This is how you can match the background or other visual components. You can use composting to combine any number of green screen footage together and also add other elements to it.
- You can add background images, videos, or graphics to create the desired environment for your subject. It may be a picture with an animated background, a video itself with a replaced background, or any other design you have in mind.
- It is advisable to use layering and masking techniques for advanced compositing effects:
- Layering different elements on the timeline to create depth will give more detail and complexity of your creation. More layers means more depth of the visual. Chroma Keying has to be performed layer by layer to be successful. The timeline will help you do this easily.
- You will have to select the layer and select the pixel color you need to make transparent.
- Using masks to isolate specific parts of layers for selective editing or blending effects is also a good trick to succeed. This helps you to easily hide certain parts of the visual and insert the effects to them.
Tips and Tricks for Green Screen Success
- The best and easiest way to make your Chroma Keying successful is to maintain proper lighting.
- You can also use pre-keyed green screen elements from online resources for convenience. These are available to be downloaded for free.
- But you should know exactly what you are looking for. If you get such elements from online, make sure you change their resolution, temperature and other contrastive features to match your original clip.
- You also can experiment these techniques with different backgrounds and try the compositing techniques to achieve creative results.
- Try performing Chroma Keying more than once for a video after adding different layers to it. This will enhance your video clip visually.
- You can create beautiful backgrounds on your own or get it downloaded and make you stand on it using a green screen. You may choose sceneries, battle fields, historical locations, locations in other countries and even fantasy backgrounds for this. Thereafter, use the blending tools to make the background and your added elements look alike.
Conclusion
Alight Motion allows you to carry out green screen editing on your videos. To complete it effectively, you should first record video in green background, carry out Chroma Keying to remove the green background and then add the desired background to the same using composting. To enhance the quality of the creation, you can use tools to bring all the visuals to a unique touch.
If you spend some time in the app, you can explore more and more composting techniques with outsourced elements as well. This will help you become more creative. For the graphic designers and those who look forward to becoming one, Alight Motion helps with all these modern techniques to create magical graphics.
