Chroma key compositing, or chroma keying, is a visual-effects and post-production technique for compositing (layering) two images or video streams together based on colour hues (chroma range). The technique has been used in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture, and video game industries. A colour range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as colour keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific colour-related variants such as green screen, blue screen and magic pink;...

A matte painting is a painted representation of a landscape, set, or distant location that allows filmmakers to create the illusion of an environment that is not present at the filming location. Historically, matte painters and film technicians have used various techniques to combine a matte-painted image with live-action footage (compositing). At its best, depending on the skill levels of the artists and technicians, the effect is "seamless" and creates environments that would otherwise be impossible or expensive to film. In the scenes the painting part is static and movements are integrated on it. Traditionally, matte paintings were made by artists using paints or...

Throughout the 1990s, traditional matte paintings were still in use, but more often in conjunction with digital compositing. Die Hard 2 (1990) was the first film to use digitally composited live-action footage with a traditional glass matte painting that had been photographed and scanned into a computer. It was for the last scene, which took place on an airport runway. By the end of the decade, the time of hand-painted matte paintings was drawing to a close, although as late as 1997 some traditional paintings were still being made, notably Chris Evans’ painting of the RMS Carpathia rescue ship in James Cameron’s Titanic. Paint has now been superseded...

How the dachshund works - Polish animated short film by Julian Antonisz- Polish visual artist, screenwriter and author of experimental animated films, composer and inventor. The film uses unconventional film techniques such as cut-out, drawing, filming of mixing fluids, as well as scratching images and drawing directly onto film, called the non-camera technique. The music for the film was created and recorded by the director himself. During the film, a commentary is read from behind the frame, similar to documentary films. https://www.youtube.com/watch?v=r16GL3N4PdM In many of his films, Antonisz deliberately employed unprepared amateurs as readers - in the case of How it Works...
