You can enter 3; transition is the switching effect, from 1 to 23, a total of 22 different switching effects, of which 23 It is a random effect.

. StartX and StartY represent the starting coordinates of the gradient transparency effect, and finishX and finishY represent the ending coordinates of the gradient transparency effect. For example, set the transparency of 50%. Effect: Blur filter: User-Defined Blur Expression: blur (pixelradius = 4, makeshadow = false) Where pixelradius sets the degree of blur. For example, set the blur effect. Effect: Chroma filter: You can use the "

the formula "RGB" in PiL is converted to "CMYK" as follows:C = 255-rM = 255-gY = 255-bK = 0Since the conversion formula is relatively simple, the converted image color is somewhat distorted.The converted image is Lena_cmyk as follows:6, Mode "YCbCr"The mode "YCbCr" is a 24-bit color image, which is represented by 24 bits per pixel. YCbCr where y refers to the luminance component, CB refers to the Blue Chroma component, and CR refers to the Red

FFmpeg x264 Encoding Guide Encoding H.264 in FFMPEG The defaults for x264 in FFMPEG are currently significantly detrimental to the quality of the encoded video. this is due to the internal behaviour of FFMPEG with respect to codec defaults. depending on the rate control method used, a number of different switches need applying to bring the settings into line with the x264 command line interface defaults. these are generally OK settings as they have been suggested by the author (s ). the necessar

seen from three dimensions of r,g,b.1.1.2YUVThe importance of YUV color space is that its luminance signal y and chroma signal u, v are separated. If only the Y signal component does not have a U, v component, then the image represented here is a black-and-white grayscale image. Color TV using YUV space is precisely to use brightness signal y to solve the compatibility problem between color TV and black and white TV, so that black and white machine c

PIC_INIT_QP_MINUS26 should be between-(+ + qpbdoffsety) to +25 (including boundary values).PIC_INIT_QS_MINUS26 indicates that the Sliceqsy initial value of all macro blocks in the SP or Si stripe is reduced by 26. When decoding a slice_qs_delta that is not a 0 value, the initial value is corrected in the stripe layer. The value of the PIC_INIT_QS_MINUS26 should be between 26 and +25 (including the boundary value).Chroma_qp_index_offset represents the offset on the parameter qpy and qsy for find

information that's now represented in these CO Lour frames (Cb and Cr) and thus these is usually sub-sampled (like in JPEG compression). The formulae for converting from RGB to YCbCr is given below.Y = (77/256)R + (150/256)G + (29/256)BCb = ‐(44/256)R ‐ (87/256)G + (131/256)B + 128Cr = (131/256)R ‐ (110/256)G ‐ (21/256)B + 128The down-sampling of Chrominance is do in 2 major variants used for most of the codecs. 4:4:4 –in This, there are no sub-sampling of the

YUV is a color coding method adopted by European television system. In modern color TV systems, a three-tube color camera or a color CCD camera is usually used to take the image and then takeThe color image signal is color-coded, respectively enlarged and corrected to get RGB, after the matrix transformation circuit, to obtain the luminance signal Y and two chroma signal r-y (U), B-y (V), and finallyThe sending side encodes three signals of brightness

large dependency between rows and rows. Generally, this method is more compressible than tiles. 6) CU A LCU is usually divided into several Cu (Coding Unit), and a LCU is represented by the CU_SPLIT flag to indicate whether a downward split is required. If the Cu_split FLAG=1,LCU is split with a quadtree, it gets four cu of the same size (the length width is half of the pre-split). Split each down once, recording the depth of the split depth plus 1. A CU consists of a luminance pixel block an

white in a solid color to change the color concentration, adding black to change the color depth, and adding different proportions of white, Black can obtain a variety of different shades. HSI Color SpaceThe HSI color space is based on the human visual system, using Hue (hue), color saturation (saturation or chroma) and brightness (intensity or brightness) to describe the color. The HSI color space can be described by a cone-space model.It is quite

the original pixel values of the macro block. There are a few grammatical elements: pcm_alignment_zero_bit: Fill bits, fill with bit zeros until byte-aligned, Pcm_sample_luma: 256 differential pixel values for luminance components; Pcm_sample_chroma: The difference pixel value of several chroma components, the actual number is specified by the color format of the stream. For example, for the most commonly used 4:2:0 format video, there are 128

difference terminal is based on the S terminal, the chroma (C) signal in the blue difference (b), Red difference (R) sent separately, its resolution can reach more than 600 lines. It usually adopts the YPBPR and ycbcr two kinds of identification, the former indicates the line-by-row scanning color difference output, the latter means the interlaced scanning chromatic aberration output. Now many TV products are based on color difference input to improv
