![]() Perfection is impossible – do the best you can.įinal Cut provides four additional tweaks at the bottom of the keyer filter: Different video formats make this easy (ProRes), while others (HDV, avchd) make this much harder. Drag the midpoint slider (where my cursor is) until the edge looks the best it can. Then, click and drag a line from the foreground to the background in the Canvas. If an edge is too pronounced, or needs help, click the Edges icon. (For REALLY bad keys, you'll need to also adjust Color Selection, mentioned below.) Adjust the Fill Holes and Edge Distance sliders until your key looks solid. Your goal is the make the foreground solid white, which means opaque, and the background solid black, which means transparent. But there are three other adjustments that can make your key look even better:Ĭlick the Matte button to display your key as a white foreground on a black background. Most of the time, you can probably stop here. I try to get close to the face, but not so close that I accidentally select loose hair or skin. ![]() In the green-screen image, drag to select a representative section of the background. This allows fine-tuning the selection of the background color. ![]() (You can also drag the effect on top of the clip, if you forgot to select the green-screen clip first.)ĭon't panic if your image looks weird – we will fix it.Ĭlick the Sample Color icon. But this is purely personal choice.įrom the Effects Browser > Keying category, double-click the Keyer effect, which applies it to the selected clip. I find it easier to put the background in the Primary Storyline, because it makes editing the green screen image easier. You can place either the green screen or background image into the Primary Storyline. The green screen image is always placed above the background. Garbage mattes are used to get rid of junk around the edges. It only needs to completely surround the edges of your actors. Don't worry about having the green background fill the frame.There is NO relationship between how the background is lit and how your actors are lit.I try to have the green background display between 40-50% level on the waveform monitor. The green background should be lit smoothly, both from side to side and top to bottom.Paint is always better than fabric avoid wrinkles and folds. The green background should be as smooth as possible.In general, don't cast shadows on the green screen.This avoids light from the background "spilling" around their body or shoulders. Actors should be at least 10 feet in front of the green screen.First, the best thing you can do to improve the quality of your keys is to improve how you shoot them.
