YouTube Rewind YouTube Rewind is a video series produced and created by YouTube and Portal A Interactive. These videos are an overview and recap of each year's viral videos, events, memes, and music. Each year, the number of YouTube celebrities featured in the video, as well as the presentation of the series, have increased. The latest episode of "YouTube Rewind" was released on December 8, 2016.

Luma (video) In video, luma represents the brightness in an image (the "black-and-white" or achromatic portion of the image). Luma is typically paired with chrominance. Luma represents the achromatic image, while the chroma components represent the color information. Converting R′G′B′ sources (such as the output of a three-CCD camera) into luma and chroma allows for chroma subsampling: because human vision has finer spatial sensitivity to luminance ("black and white") differences than chromatic differences, video systems can store and transmit chromatic information at lower resolution, optimizing perceived detail at a particular bandwidth.

Backup camera A backup camera (also called reversing camera) is a special type of video camera that is produced specifically for the purpose of being attached to the rear of a vehicle to aid in backing up, and to alleviate the rear blind spot. Backup cameras are alternatively known as 'reversing cameras' or 'rear view cameras'. It is specifically designed to avoid a backup collision. The area directly behind vehicles has been described as a "killing zone" due to the associated carnage.

Global motion compensation Global motion compensation "(GMC)" is a technique used in video compression to reduce the bitrate required to encode video. It is most commonly used in MPEG-4 ASP, such as with the DivX and Xvid codecs.

Apple Intermediate Codec The Apple Intermediate Codec is a high-quality 8-bit 4:2:0 video codec used mainly as a less processor-intensive way of working with long-GOP MPEG-2 footage such as HDV. It is recommended for use with all HD workflows in Final Cut Express, iMovie, and until Final Cut Pro version 5. The Apple Intermediate Codec abbreviated AIC (by users, Apple Engineers don't use the abbreviation) is designed by Apple Inc. to be an intermediate format in an HDV and AVCHD workflow. It features high performance and quality, being less processor intensive to work with than other editing formats. Unlike native MPEG-2 based HDV - and similar to the standard-definition DV codec - the Apple Intermediate Codec does not use temporal compression, enabling every frame to be decoded immediately without decoding other frames. As a result of this, the Apple Intermediate Codec takes three to four times more space than HDV.

Response Time Compensation Response time compensation is also known as "Overdrive". LCDs moderate light flow by rotating liquid crystal molecules to various alignments where they transmit more or less light depending on the electrical setting at each individual pixel. The speed at which these liquid crystal molecules rotate is relatively slow, below the image refresh rate. As a consequence, when a scene is changing fast or there is a fast moving image being displayed (such as a golf ball flying off the head of a club) the object is at best blurry and can disappear from the image entirely. Overdrive attempts to compensate for this by, instead of sending the desired voltage to each pixel, it sends a higher initial voltage and then moderates that voltage in order to drive the rotation of the liquid crystal faster. Electrically it "steps on the gas" in order to get to the right speed quickly, then eases off as it approaches the desired performance level.

Commercial skipping Commercial skipping is a feature of some digital video recorders that makes it possible to automatically skip commercials in recorded programs. This feature created controversy, with major television networks and movie studios claiming it violates copyright and should be banned.

Digital component video Digital component video is defined by ITU-R BT.601 (formerly CCIR 601) standard and uses the Y'CbCr colorspace. Like Analog Component Video it gets its name from the fact that the video signal has been split into two or more components, that are then carried on multiple conductors between devices. Digital component video is slowly becoming popular in both computer and home-theatre applications. Component video is capable of carrying signals such as 480i, 480p, 576i, 576p, 720p, 1080i and 1080p, although many TVs do not support 1080p through component video.

Cutting on action Cutting on action or matching on action refers to film editing and video editing techniques where the editor cuts from one shot to another view that matches the first shot's action.

Nominal analogue blanking Nominal analog blanking or nominal analogue blanking is the outermost part of the overscan of a standard definition digital television image. It consists of a variable and arbitrary gap of black (or nearly black) pixels at the left and right sides, which correspond to the end and start of the horizontal blanking interval: the front porch at the right side (the end of a line, before the sync pulse), and the back porch at the left side (the start of a line, after the sync pulse and before drawing the next line). Digital television ordinarily contains 720 pixels per line, but only about 702 (PAL) to 704 (NTSC) of them contain picture signal. The edge may not be clean — some blurring can occur — and the location is arbitrary, since analogue equipment may typically shift the picture sideways in an unexpected amount or direction. Really old analogue equipment can cause the total width of 'active picture' to vary, usually down, perhaps to as few as 680 pixels.

Fade (lighting) In stage lighting, a fade is a gradual increase or decrease of the intensity of light projected onto the stage. The term fade-in refers to gradually changing the lighting level from complete darkness to a predetermined lighting level. A fade-out (also known as fade-to-black) refers to gradually decreasing the intensity of light until none is shining on the stage. A "crossfade" is when lighting levels are gradually altered from one setting to another. A fade-in is sometimes called a "build", and where this terminology is used, a fade is understood to be a fade-out.

Component video sync Component video requires an extra synchronization signal to be sent along with the video. Component video sync signals can be sent in several different ways:

DVD recordable DVD recordable and DVD rewritable refer to part of optical disc recording technologies. DVD optical disc formats that can be recorded by a DVD recorder, (written, "burned"), either write once or rewritable (write multiple times) format written by laser, as compared to DVD-ROM, which is mass-produced by pressing, primarily for the distribution of home video. "DVD recordable" is a general term that refers to both write-once and rewritable formats, whereas "DVD rewritable" refers only to rewritable formats.

DTE (direct to edit) DTE (direct to edit) is a digital video direct-to-disk recording method (and also refers to the associated equipment) used to streamline the post-production video editing workflow of raw video files into a Non-linear editing system (NLE). Recent developments have added solid-state memory recording units with removable modules or flash-cards, to avoid potential hard-drive problems.
