But - using mode keywords - part of this corrected frame may be replaced by the corresponding part of a Ref frame (-F keyword) like colorbars, thus enabling to visually adjust correction to match the reference frame. Possible mode keyword are: FULL (default) HALF_LEFT The generated frame is now constituted of two different parts: the left half shows the final reference uncorrected while the right half shows it corrected HALF_RIGHT Same as HALF_LEFT except right and left are inversed QUARTER_LEFT Same as HALF_LEFT except the uncorrected part is only a quarter of the image QUARTER_RIGHT Same as HALF_RIGHT except the uncorrected part is only a quarter of the image 3QUARTER_LEFT The left three quarters of the image is uncorrected, the right quarter corrected 3QUARTER_RIGHT The right three quarters of the image is uncorrected, the left quarter corrected TOP the top half is uncorrected, the bottom half is corrected BOTTOM the bottom half is uncorrected, the top half is corrected RGBFIRST to have yuvcorrect_tune apply RGB corrections first, then YUV corrections Possible yuv keywords are: LUMINANCE_Gamma_InputYmin_InputYmax_OutputYmin_OutputYmax Y_Gamma_InputYmin_InputYmax_OutputYmin_OutputYmax to correct the input frame luminance by clipping it inside range [InputYmin;InputYmax], scale with power (1/Gamma), and expand/shrink/shift it to [OutputYmin;OutputYmax] CHROMINANCE_UVrotation_Ufactor_Urotcenter_Vfactor_Vrotcenter_UVmin_UVmax UV_UVrotation_Ufactor_Urotcenter_Vfactor_Vrotcenter_UVmin_UVmax to rotate rescaled UV chroma components Ufactor*(U-Urotcenter) and Vfactor*(V-Vrotcenter) by (float) UVrotation degrees, recenter to the normalize (128,128) center, and _clip_ the result to range [UVmin;UVmax] CONFORM to have yuvcorrect_tune generate frames conform to the Rec.601 specification for Y'CbCr frames that is LUMINANCE_1.0_16_235_16_235 and CHROMINANCE_0.0_1.0_128_1.0_128_16_240 Possible RGB keywords are: R_Gamma_InputRmin_InputRmax_OutputRmin_OutputRmax G_Gamma_InputGmin_InputGmax_OutputGmin_OutputGmax B_Gamma_InputBmin_InputBmax_OutputBmin_OutputBmax to correct the input frame RGB color by clipping it inside range [InputRGBmin;InputRGBmax], scale with power (1/Gamma), and expand/shrink/shift it to [OutputRGBmin;OutputRGBmax] How to use the keyboard: Pressing Y, U, V, R, G, B or M will tell yuvcorrect_tune that all following keystrokes refer to corrections applied to Y values, UV values, UV values, R values, G values, B values, Mode of yuvcorrect_tune ; until ESCAPE is pressed To define corrections, use Capital letter to increase and minor letter to decrease Gamma values are changed by amount of 0.01, Ufactor and Vfactor by 0.05; UVrotation by amount of 1 degree; Integer values by 1 To modify the 1st, 2nd, 3rd, 4th, 5th, 6th or 7th parameter, use respectively e/E, r/R, t/T, y/Y, u/U, i/I, o/O To modify yuvcorrect_tune mode, use keypad values 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 For status, press S.
