Video matting. Video matting is a technique for separating the video into two or more layers, usually foreground and background, and generating alpha mattes which determine blending of the layers. The technique is very popular in video editing because it allows to substitute the background, or process the layers individually.
Matte (filmmaking) Mattes are used in photography and special effects filmmaking to combine two or more image elements into a single, final image. Usually, mattes are used to combine a foreground image (e.g. actors on a set) with a background image (e.g. a scenic vista or a starfield with planets). In this case, the matte is the background ...
Basics of image editing. Raster images are stored in a computer in the form of a grid of picture elements, or pixels. These pixels contain the image's color and brightness information. Image editors can change the pixels to enhance the image in many ways. The pixels can be changed as a group, or individually, by the sophisticated algorithms ...
Chroma key is achieved by comparing the phase of the video to the phase corresponding to the pre-selected colour. In-phase portions of the video are replaced by the alternate background video. [citation needed] In digital colour TV, colour is represented by three numbers (red, green, blue intensity levels).
adobe .com /aftereffects.

Type. Video editing software. License. Proprietary. Adobe Ultra is a discontinued vector keying application, helping produce blue-screen / green-screen effects for video (although the background can actually be any color). Ultra performs complex image analysis to produce high quality chroma-key effects in less than ideal lighting environments.
Primatte is a brand of chroma key software used in motion picture, television and photographic host applications to remove solid colored backgrounds ( greenscreen or bluescreen usually) and replace them with transparency to facilitate ‘background replacement’. It uses a unique algorithm based on three multi-faceted polyhedrons floating in ...
VSDC Free Video Editor is a non-linear editing (NLE) application developed by Flash-Integro LLC. The program [1] is capable of processing custom resolutions, including high-resolution footage such as 4K UHD, 3D and VR 360-degree videos. VSDC is designed to apply post production effects, live color correction, and motion tracking.
Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio .
Cropping (image) Cropping is the removal of unwanted outer areas from a photographic or illustrated image. The process usually consists of the removal of some of the peripheral areas of an image to remove extraneous visual data from the picture, improve its framing, change the aspect ratio, or accentuate or isolate the subject matter from its ...
