In the nascent days of cinema, the introduction of double role was a kind of amusement for the global audience. During those days basic chroma keying was used to clone characters. A chroma key is a technique used in film, video and still
photography to replace a portion of an image with a new image. This is
most commonly used to replaced a coloured background with a different
setting. The most common colours used in chroma keys are blue and green, because
these colours are least likely to affect the foreground shot.Now the technology has developed a lot and making double roles is as simple as cropping an image. You can easily create double role or clone yourselves using Adobe Premiere Pro.
This tutorial will help you to create double role without any chroma keying.
