This is what you want the key to look like, a black and white cut-out of your subject.Д®ven though the key looks good on a single frame, itвЂ™s a good idea to skim over the entire clip because if youвЂ™re lighting changes, youвЂ™ll need to drag out more samples. To refine the key, click the Sample color button, then drag out a box over the area of gray pixels. But right now there is too much gray in the background and it needs to be removed. To achieve a good key you want as much of your subject in white, as much of your background in black, and the edges surrounding your subject in gray to create a smooth transition between the subject and the background. The black areas are the transparent pixels, the areas where the background completely shows through, and the gray areas are where some of the background shows through. The white areas are the opaque pixel, the areas where no background shows through. The matte view is helpful because it shows you which pixels are opaque, which ones are transparent, and which ones are semi-transparent. The first place to begin when evaluating your key is the matte view. In my experience, leaving this slider at 100% is the best starting place to begin making improvements to the key.

With the strength slider at 100, full automatic keying is applied, and with the strength slider set at 0, no keying is applied. Be default, Final Cut Pro applies an automatic keyer by choosing the best range of green pixels from which to create the key. In the Inspector, reveal the Keyer controls. The keyer begins its work of knocking out most of the green pixels, giving us a very rough composite. IвЂ™ll apply the effect by dragging it onto the clip. You can also see this hot-spot by skimming over the clip. The dark spot indicates an area where the light was too close to the wall. Instantly, we can see some problems with the lighting in the scene. IвЂ™ll locate the Keyer in the Keying category then skim over the thumbnail to see a preview. If your subject moves, make sure to scrub over your clip to ensure the cropping wonвЂ™t be cutting off some of your subject.ДЇor the next step, IвЂ™ll park the playhead over the greenscreen clip and open the Effects Browser. IвЂ™ll press Shift-C to call up the crop tool, then crop out the unwanted pixels. Here, we see part of the set at the right and left edges of the frame. Before you apply a keyer effect, you should remove any area in the frame that wonвЂ™t be part of the final composite to make it easier for the keyer to evaluate the image and give you a good key right out of the box. I connected an audition clip containing some images of a vineyard to be used as the background.

If youвЂ™d like to know what paint I use, thereвЂ™s a link in the description section below. Here heвЂ™s doing some of his dub-step moves in front of a 1010 chromakey green painted wall. ItвЂ™s the season for wearing silly costumes, and my son Andy found this inflatable suit that makes him look like aвЂ¦giant grape.
