Interlacing was invented as a means to reduce flicker in early mechanical and CRT video shows with out expanding the amount of entire frames per next. Interlacing retains detail even though requiring decrease bandwidth in comparison with progressive scanning.[ten][eleven]

Pixels on Pc monitors are often square, but pixels used in electronic video normally have non-sq. component ratios, such as those Employed in the PAL and NTSC variants with the CCIR 601 electronic video common along with the corresponding anamorphic widescreen formats.

Video can be interlaced or progressive. In progressive scan devices, Each and every refresh interval updates all scan lines in Each individual frame in sequence. When exhibiting a natively progressive broadcast or recorded sign, the result could be the optimum spatial resolution of both equally the stationary and moving portions of the image.

Uncompressed video provides greatest top quality, but at an extremely higher data amount. Various strategies are utilized to compress video streams, with the best kinds utilizing a team of pictures (GOP) to reduce spatial and temporal redundancy. Broadly speaking, spatial redundancy is decreased by registering dissimilarities amongst parts of one frame; this process is called intraframe compression which is closely relevant to image compression.

A lot of analog and electronic recording formats are in use, and digital video clips can even be saved on a computer file technique as data files, which have their unique formats.
