What is video encoding? Part 2<\/strong><\/p>\n

\"video<\/p>\n

Bit rate – bit rate<\/p>\n

\"video<\/p>\n

The bit rate is the bit rate of the data transmission, that is, the number of bits transmitted per unit of time, generally measured in bits per second. When encoding video, a distinction is made between video and audio bit rate; During encoding, each parameter is set to its own value and does not depend on the other.<\/p>\n

Shine – shine
\n(1) Intensity of color, measured from black (zero brightness) to white (maximum brightness).<\/p>\n

CBR \/ VBR constant \/ variable bit rate
\nConstant Bit Rate \/ Variable Bit Rate: Constant \/ Variable Bit Rate. With a constant bit rate, the same number of bits is allocated for each frame of the movie. With a variable bit rate, frames that require better quality get more bits and vice versa. Note that dynamic movie scenes require more bits than smooth scenes.<\/p>\n

Codec -codec
\nCOder \/ DECoder – COder-DECoder (short codec): A codec is a piece of software that allows you to encode data (usually audio or video) in a specific format, and it can also decode data encoded in this format. Popular codecs: MPEG -1, MPEG -2, MPEG -4, Indeo, etc.<\/p>\n

AVI, ASF and others are not codecs, but data formats that can be obtained using codecs.<\/p>\n

Composite video – composite video
\nThis is a signal in which luminance, chrominance, and timing are combined into a single signal used in the television broadcast standard.<\/p>\n

Decoding – decoding
\nThe term Decoding describes the process of converting a compressed (encoded) file into a viewable image.<\/p>\n

Deinterlace – deinterlace (remove interlacing)
\nIt is the process of removing artifacts caused by the nature of interlaced video (two fields per frame). Otherwise, it is called the “comb effect.”<\/p>\n

Encoding – encoding
\nIt is the process of compressing a “raw” uncompressed file by encoding it in a given format while maintaining a certain quality.<\/p>\n

FilmFX
\nThis post-processing algorithm adds “warmth” to video for those users who like warm tones rather than the clarity of digital video. The FilmFx filter is best suited not only for adding warmth to a movie, but also for reducing perceived blockage in digital video and decreasing processor load during decoding.<\/p>\n

Frame – frame
\nThis is the basis of the entire film, one frame represents one image. Film generally runs at 24, 25, or 30 frames per second, which is equivalent to displaying 24 (25 or 30) images per second. Imagine 24 images of one bird each. In the first image, the bird is on the left, in each subsequent image, it gradually shifts to the right, in the last image, the bird is on the right edge. When these 24 images are displayed in sequence very quickly, the human eye will see the bird flying from left to right.<\/p>\n

Global motion compensation: general motion compensation
\nGlobal Motion Compensation (GMC) – Global Motion Compensation helps enhance complex scenes including panning and zooming. The ability to reduce the amount of data from one frame to the next may be diminished as there are some similarities between panning and zooming an image. To more effectively compensate for movement, this similarity can be exploited in the groups of blocks found most frequently in such scenes.<\/p>\n

Keyframe – Keyframe
\nFull frame, but highly compressed (compressed).<\/p>\n","protected":false},"excerpt":{"rendered":"
