Adobe After Effects is an image editing software application used for motion graphics, compositing, and visual effects. With it you can produce engaging videos for your target audience.
Before using the green screen feature in After Effects, make sure that all footage shot against a solid color background has been captured properly. After that, apply Keylight + Key Cleaner + Advanced Spill Suppressor effects to your footage for optimal results.
Keylight
Green screens present limitless opportunities for filmmakers and photo creators alike to craft engaging content. Filmmakers can layer any desired background within a controlled environment, opening the door for creative compositing effects to make content even more captivating and captivating. But before beginning work on your masterpiece, be sure that all necessary background footage has been secured – that means ensuring Adobe After Effects correctly keys out the green screen in advance.
To correctly key out your footage, the Keylight effect must first be added. You can find this effect in After Effects effects library by going to Window > Effects & Presets and choosing Animation Presets dropdown at top panel. Once you find an appropriate preset for you green screen footage, just drag and drop.
Once the Keylight effect has been applied to your footage, you must tell it which color backdrop to select. To do so, use the eyedropper tool next to Screen Color option in effects panel to click a section of green screen closest to your subject; once selected change its View setting from Screen Matte in Effect Controls panel before fine-tuning settings until achieving an excellent keylight keying result.
If you want to fine-tune the key further, this After Effects green screen replacement preset includes Key Cleaner and Advanced Spill Suppressor options which work in tandem with Keylight to reduce green hue around your subject and prevent unnecessary noise in composited scenes.
Once you are happy with the results of your green screen keying session, it is time to move onto compositing. In After Effects, import background footage and place it underneath your green screen footage in the timeline. In certain instances, use of the Pen tool may also be necessary in creating masks around your subject depending on their subject matter.
Key Cleaner
Green screen (chroma key) is a crucial tool in video and image production that enables filmmakers to add subjects from one scene into another scene without physically having them present in both scenes simultaneously. Filmmakers use green screens for this reason and to create custom backgrounds in videos or digital content creation; its use offers endless creative potential! However, green screening may be intimidating to beginners; finding suitable lighting conditions and masking subjects correctly may prove challenging; fortunately After Effects offers two built-in tools designed specifically to aid this process; these being Keylight and Key Cleaner effects which should help.
After Effects provides two effects known as Keylight and Key Cleaner that you can access from its effect menu. Use Keylight to make transparent any portion of green screen footage you select; afterward use Key Cleaner to eliminate any rough edges and ensure your subject is clear; additionally you can utilize Advanced Spill Suppressor for any color spill around your subject.
The Keylight effect offers various controls that enable you to finely tailor its opacity in both foreground and background areas, among other properties. Within its Effect Controls panel, you can choose a Key Color that identifies pixels that should become transparent; and set both Matching Tolerance and Softness values which set how closely their pixels must match up against this key color before becoming transparent.
Edge Feather allows you to control the size of foreground and background regions, with higher values decreasing both sizes while rendering takes longer. Finally, choose Blend With Original to determine how well foreground and background should blend together.
If you want to restore a color that was rendered transparent by Keylight, simply reapply the effect and select Keep Colors in its Key Operation menu. Alternately, Inner/Outer Key can help with modifying colors around an object to remove background pixels that could contaminate its keyed border and reduce halo effects when matted against new backgrounds.
Advanced Spill Suppressor
Green screen is an incredible tool that allows video and photo creators to switch out footage for any background they desire post production, giving limitless possibilities for creating engaging digital content. However, in order to get the most from green screen usage – particularly for video compositing or visual effects work where keying processes may prove tricky – proper usage must be understood.
At the core of video compositing lies getting your subject separated from its background. To do this, create a mask around them using the pen tool before applying a keying effect – once that has taken place you can replace any green background footage with anything you like!
Acquiring an effective key can be challenging even for the most seasoned video creators, due to the many variables at play. Lighting the green screen correctly and making sure your subject contrasts well are key factors to consider, while it is equally essential that creases or shadows don’t disrupt the keying process.
Adobe After Effects provides tools that can help reduce color spill from the background that affects your subject, such as Advanced Spill Suppressor for chroma keying to reduce this problem. It is especially effective at eliminating green spill and maintaining hair detail and other fine details in foreground subjects.
To achieve optimal results when using After Effects, Adobe suggests using a combination of Keylight, Key Cleaner and Advanced Spill Suppressor effects – available both within Animation Presets folder and Image — Utilities category of Effects panel. You can find these animation presets by clicking Window – Effects & Presets icon located in top menu bar of After Effects – when this window is active you can drag Keylight+Key Cleaner+Advanced Spill Suppressor onto green screen footage to start working with it immediately.
Edge Feather
The Edge Feather command softens selection edges, helping it blend in more easily with its surrounding. Similar to feather features found on many selection tools, you can apply Edge Feather by selecting part of an image or video and going to Select > Modify > Feather Selection from your menu bar. In Feather Selection dialog box enter desired feather radius value; higher numbers soften edges further.
After Effects is an advanced software used for visual effects compositing. Its green screen removal feature can be invaluable in creating professional-looking videos; however, newcomer video editors may find it challenging to master all its various functions. In this article we’ll show how you can use various techniques in After Effects to successfully remove green screen.
Green screens are used in film and video production to distinguish subjects from backgrounds that can be altered later in post-production, enabling video editors to customize these backgrounds as needed by replacing it with new footage or background material. Adobe After Effects’ Green Screen feature simplifies this process for editors.
To remove green screen in After Effects, first open a composition and then select the green screen layer. Clicking on the eye dropper icon next to Screen Color option and pointing at a section of green screen in your video clip will eliminate most of it from your video clip; using Keylight, Key Cleaner or Advanced Spill Suppressor may further refine and smooth out remaining sections of green screen in After Effects.
After Effects provides the option for creating masks with variable feathering for greater control over selections. This feature is particularly effective at eliminating green screen from footage for more realistic results.
