For this tutorial I’m using footage from Hollywood Camera Work which you can download here. You’ll want a camera that can record 444 colour resolution to a native or RAW format. The colour resolution, pixel resolution, green screen lighting and recording format play a huge role in the keying software’s ability to do it’s job. It should be said that the most important aspect of getting a good key is the one you might not be able to control: the footage.

This will take our keys to a level above single pass keying and will still be quick enough to do even on the tightest deadlines. For this tutorial we’ll only cover the essential three passes: the super tight garbage matte, the core matte and the edge matte. But good keys require multiple passes: garbage mattes, core mattes, edge mattes, spot fixes and yes, possibly rotoscoping. They’ll be forced to push the clip white and black sliders too far and end up with a harsh, unsatisfactory matte. In the context of After Effects that’s one Keylight effect on one piece of footage. Many times artists will try and do a key in one pass. In this tutorial we’re going to explore the triple pass keying method in After Effects. Work and time which you need to put into your shots to pull good quality mattes. But that’s very seldom the case, pulling a matte takes WORK. There’s a misconception that keying is an almost one click, five minute process and that if the results are unsatisfactory that there is something wrong with the keying software. Be brutal, complete, and quick this can be crude ( see Figure 9).I have often noticed that those who are new to compositing and VFX go about their green screen keying the wrong way. You can lower the Screen Shrink/Grow setting (under Screen Matte in Keylight) or apply a Simple Choker effect and raise the Choke Matte number. If necessary, choke this matte further to eliminate tracking markers and other small bits of noise.In Keylight Status or Combined Matte view (depending on your preference), raise Clip Black just enough to remove gray pixels from the background in Status view, and then lower the Clip White setting to just above the same number ( see Figure 8).To create this layer, follow these steps: For clarity’s sake, turn off effects for Edge for the moment.The goal with this layer is to create a background matte that’s 100% transparent and outside of all edge detail by several pixels. Duplicate this layer (Keylight still applied), rename it Background, and solo it.(Enable Move All Attributes in the Pre-compose dialog box.) Rename the layer Edge. Create a pre-comp containing the Keylight layer created with the previous steps.

This breakdown will work with any software keyer, but it’s especially helpful to get the most out of Keylight. The three-pass method is the same principle, but it should save you from extensive hand-animating. Keylight’s Inside Mask and Outside Mask controls let you draw a mask, set it to None, and then select it as an Inside Mask or Outside Mask. This method of isolating and focusing on the edge inspired me to devise the following workflow to achieve the same in an After Effects pre-comp, with as few extra steps as possible. The Apple Shake-based implementation of Keylight adds inputs for a garbage matte and holdout matte. ( Figure 1 shows the original image Figure 2 and Figure 3 show two possible results.) Then you can delete the rest.Now, as needed, look for areas to refine.įigure 7 Nice edges-it’s the core of this matte that needs to be a little firmer.

Set the background to a bright color and solo the plate layer, or examine the alpha channel by pressing Alt-4 (Mac: Option-4). View defaults to Final Result so you get a matte instantly.

In the best-case scenario, you create any necessary garbage mattes and then follow these steps: (Keylight reveals its UK origins at Framestore CFC with that u in word Colour.) The first decision in Keylight is most important: sampling a color for the Screen Colour setting.

The use of Keylight in After Effects CS4 is more or less identical to that of previous versions. Keylight is useful when preservation of edge detail is of utmost importance-most typically (but not exclusively) when working with footage that was shot specifically to be keyed against a screen of either blue or green.

Here is a tutorial for how to use keylight. When we doing digital composting, the key light effect we used very frequently.
