![]() To accomplish this, the first thing we are going to do is drag our foreground image to the primary storyline in our Timeline, then connect the background image below it. So we can place it over the background image: However, you can adjust the settings to remove light colors instead.įor this example, we are going to remove the white background of the foreground image (shown below). You use this effect when the foreground image does not have the greenscreen, but you still need to remove parts of it. As we stated in the last paragraph, by default, the Luma Key effect will make the darkest parts of the image (black) transparent. The Luma Key effect will allow you to place a foreground clip over a background clip, then remove parts of the foreground clip based on the luminance levels. Typically, black will become transparent and you will get to decide what to do with grey. You can use this to further refine hair or reflections in the foreground image. To refine other areas, click the Edges thumbnail in the Video Inspector, then draw a line across the area in the Viewer. Go to the Viewer, and draw a rectangle where the green color needs to be removed. To remove any green that still may be showing in the foreground clip, click on the Sample Color thumbnail in the Video Inspector. Next, go to the Viewer and Video Inspector. ![]() To do this, select the foreground clip in the Timeline, then select the Select tool in the toolbar. Once you have applied the keyer effect, you can then modify it to improve it. When we look at the Viewer, we can see purple tree has been keyed over the forest. To see the keyer effect on your foreground clip, use the skimmer to move through the clips, or playback the connected clips. You can then drag the effect to the foreground clip. In the Effects browser, select Keying from the left hand side, then the Keyer effect, as shown below. Now, click the Effects button in the toolbar. Select the foreground clip in the Timeline. In the snapshot below, you can see that our two clips are connected. Next, drag the background clip – or the one that will be on bottom, and connect it below the foreground clip. The clip with color that you want to remove will always be the foreground clip – or the one on top. The clip shown above is the foreground clip, or the clip that will be on top. In other words, we want to take the tree from this clip and combine in with a clip of a forest. We want to make it so that the tree is keyed over a forest scene. The best way to learn to use the chromakeyer effect is to show you how to work with it in Final Cut Pro X.īelow is a clip of a purple tree that was shot in front of a greenscreen. If you are filming one subject, such as a person, use a tripod L bracket and mount the camera vertically for higher resolution and higher pixel density around the subject.Make sure the background is evenly lit.When you record your footage, record in progressive instead of interlaced format.Use a camera with a high ISO starting value. ![]() Use a camera that does not interpolate to attain HD resolution. HDV cameras do this.However, here are some things you can do to make it even easier for you: Using the keyer effects in Final Cut Pro X is not difficult. ![]() You can remove white or black areas, plus decide if grey areas should be partially transparent. Luma Keyer generates mattes based on the lightness of the image. Greenscreening is used for network news during weather forecasts.įinal Cut Pro X offers two keyer effects. Keying is also known as greenscreening or chromakeying. It involves replacing a color in an image with parts from a background image. Typically, the color green is replaced with a background image. Compositing is defined as combining two images in a scene and making it appear as if they were shot together.
