Using chroma key for video making, movie making and its vast usefulness has been highlighted throughout several movies like the Harry Potter any and all Super Hero Movies and anywhere it was not possible to create an almost realistic video effects to provide that kind of awe to match imagination in storyline.  Chroma Key is almost magical or atleast highly technical and interesting concept of video making, this is where two previously created videos, images, image and videos can be merged together to seem like one.

Two different video sequences like an animation or an imaginary set can be merged with real actors and actresses doing their bit in real storyline. Chroma key is available in every video editing software. It is ideal to have a set of extra ordinary setting that could greatly bring out the best from the chroma key feature. Larger softwares offer that kind of array of settings. When it comes to chroma key, all settings happen inside keyframes. Of course, thinking of chroma key as a giant green curtain would be wrong. Green or blue are two colors used for this effect during the shooting of a sequence only to avoid bleeding of color into another space while editing. At times, the curtains take only half the space if the background is different or animated when the sequence is made.

Avengers and Harry Potter are two good examples about how the green screen or the Chroma Key was put into use very efficiently. Here, since there were tiny effects included throughout in the movies you could see floating candles, cupcakes, flying animals and birds, giant dragons, submerged water scenes, etc., where every expertise was used in large canvas or smallest of spaces like the hands. Imagination of the director of the movie and the technical directors as well as the VFX team are the ones who know how to use Chroma key to their benefit.
