2. Luma (video) - Wikipedia

   en.wikipedia.org/wiki/Luma_(video)

   Luma is the weighted sum of gamma-compressed R′G′B′ components of a color video—the prime symbols ′ denote gamma compression. The word was proposed to prevent confusion between luma as implemented in video engineering and relative luminance as used in color science (i.e. as defined by CIE).

3. Chrominance - Wikipedia

   en.wikipedia.org/wiki/Chrominance

   Luminance only, Chrominance only, and full color image. Chrominance ( chroma or C for short) is the signal used in video systems to convey the color information of the picture (see YUV color model), separately from the accompanying luma signal (or Y' for short).

4. Gamma correction - Wikipedia

   en.wikipedia.org/wiki/Gamma_correction

   "Luminance" can mean several things even within the context of video and imaging: luminance is the photometric brightness of an object (in units of cd/m 2), taking into account the wavelength-dependent sensitivity of the human eye (the photopic curve); relative luminance is the luminance relative to a white level, used in a color-space encoding ...

5. Video codec - Wikipedia

   en.wikipedia.org/wiki/Video_codec

   A short video explaining the concept of video codecs. A video codec is software or hardware that compresses and decompresses digital video.In the context of video compression, codec is a portmanteau of encoder and decoder, while a device that only compresses is typically called an encoder, and one that only decompresses is a decoder.

6. HCL color space - Wikipedia

   en.wikipedia.org/wiki/HCL_color_space

   Luminance (Y or L v,Ω) The radiance weighted by the effect of each wavelength on a typical human observer, measured in SI units in candela per square meter (cd/m 2). Often the term luminance is used for the relative luminance, Y/Y n, where Y n is the luminance of the reference white point. Colorfulness

7. Luminance - Wikipedia

   en.wikipedia.org/wiki/Luminance

   A luminance meter is a device used in photometry that can measure the luminance in a particular direction and with a particular solid angle. The simplest devices measure the luminance in a single direction while imaging luminance meters measure luminance in a way similar to the way a digital camera records color images.

8. Video editing software - Wikipedia

   en.wikipedia.org/wiki/Video_editing_software

   Since video editors represent a project with a file format specific to the program, one needs to export the video file in order to publish it.. Once a project is complete, the editor can then export to movies in a variety of formats in a context that may range from broadcast tape formats to compressed video files for web publishing (such as on an online video platform or personal website ...

9. SMPTE color bars - Wikipedia

   en.wikipedia.org/wiki/SMPTE_color_bars

   Typically, a television network, TV station, or other originator of video programming transmits SMPTE color bars together with a continuous 1,000 Hz sine wave before sending program material, in order to assert ownership of the transmission line or medium, and so that receiving stations and intermediary telecommunications providers may adjust ...
