Using Picture Profile presets with S-Log
Thanks @royalstar22500.What I need is the official one and not a look LUT. Every camera has its official LUT from its profiles to the convention color spaces like rec709 and rec2020. Its not simple gamma curve. A Conversion LUT translates the flat V-Log material to a more restricted, yet contrasty, Dynamic Range and shifts the color space to match the monitor, bringing both parameters to a technical standard for viewing such as Rec. These conversion LUTs provide a neutral matching of the signal to the monitor, so they can be considered technical.

These two LUTS are for the HERO7 Black firmware v1.51 only, I have no idea how they will look on older Hero versions.
When shooting in S-Log, use Picture Profile presets PP7, PP8, or PP9.
The PP7 preset combines S-Gamut and S-Log2, while PP8 is S-Gamut3.cine/S-Log3 and PP9 is S-Gamut3/S-Log3. Here, select PP7 (S-Gamut/S-Log2) and leave the preset details as-is. A distinction of this Picture Profile, intended for subsequent color grading, is a gamma broad enough for movie production.

Why Log video looks faded and low-contrast
Often, gamuts used in professional video applications conform to ITU-R BT.709 (Rec. 709), established for HDTVs. This is illustrated below.

Here, the curved color space represents the range of human vision. Newport wave e200 ventilator manual. The gamut of Rec. 709 is much narrower. In contrast, it is easy to appreciate how much broader S-Gamuts used in S-Log recording are. Pc multimeter software free download software.
When viewed on a screen designed for Rec. 709, Log video lacks contrast because the screen cannot display the full gamut.

Easily reproducing colors on Rec. 709 screens with 3D LUTs
Optimal display of Log video on Rec. 709 screens requires color grading, when you will use lookup tables (LUTs). This conversion prepares the material for display on Rec. 709 screens.
Unlike 1D LUTs, which mainly adjust luminance, 3D LUTs control hue, saturation, and brightness of each RGB color. LUTs simplify color grading, because without them, instant S-Log video display matching the gamut of Rec. 709 screens would be difficult as you adjust tone curves, hue, saturation, and other details two-dimensionally.

When ILCE-7SM3 has recorded movies in the [S-Log3] gamma and S-Gamut3.Cine under Color Mode or S-Gamut3 under Color Mode, you can use this LUT.
Using Gamma Display Assist and external monitors
To make it easier to check S-Log video on a Rec. 709 screen as you shoot, use Gamma Display Assist to apply LUTs. The contrast of viewfinder and monitor display will look as if you were not shooting in S-Log. In this way, Gamma Display Assist enables precise camerawork, whether you are checking subjects or adjusting the focus.
You can also take advantage of LUT-compatible external monitors, which are now more common.

This video introduces shooting in S-Log and shows how effective it can be.
When shooting in S-Log, you can choose S-Log2 or S-Log3. Colors are reproduced differently depending on your choice, so use the right option for your workflow.
In this video, you can see how S-Log2 colors differ from those of S-Log3.

ITU-R Recommendation BT.709, also known by the abbreviations Rec. 709, BT.709, and ITU709, standardizes the format of high-definition television, having 16:9 (widescreen) aspect ratio. The first edition of the standard was approved in 1990.
Technical details[edit]
Pixel count[edit]
Rec. 709 refers to HDTV systems having roughly two million luma samples per frame. Rec. 709 has two parts:
Part 2 codifies current and prospective 1080i and 1080p systems with square sampling. In an attempt to unify 1080-line HDTV standards, part 2 defines a common image format (CIF) with picture parameters independent of the picture rate.
Part 1 codifies what are now referred to as 1035i30 and 1152i25 HDTV systems. The 1035i30 system is now obsolete, having been superseded by 1080i and 1080p square-sampled ('square-pixel') systems. The 1152i25 system was used for experimental equipment in Europe and was never commercially deployed.[citation needed]
Frame rate[edit]
Rec. 709 specifies the following picture rates: 60 Hz, 50 Hz, 30 Hz, 25 Hz and 24 Hz. 'Fractional' rates having the above values divided by 1.001 are also permitted.
Initial acquisition is possible in either progressive or interlaced form. Video captured as progressive can be transported with either progressive transport or progressive segmented frame (PsF)transport. Video captured as interlaced can be transported with interlace transport. In cases where a progressive captured image is transported as a segmented frame, segment/field frequency must be twice the frame rate.
In practice, the above requirements result in the following frame rates ('fractional' rates are specified in commonly used 'decimal' form): 25i, 25PsF, 25p, 50p for 50 Hz systems; 23.976p, 23.976PsF, 24p, 24PsF, 29.97i, 29.97p, 29.97PsF, 30PsF, 30p, 59.94p, 60p for 60 Hz systems.
Digital representation[edit]
Rec. 709 defines an R’G’B’ encoding and a Y’CBCR encoding, each with either 8 bits or 10 bits per sample in each color channel. In the 8-bit encoding, the R’, B’, G’, and Y’ channels have a nominal range of [16.235], and the CB and CR channels have a nominal range of [16.240] with 128 as the neutral value. So in R’G’B’, reference black is (16, 16, 16) and reference white is (235, 235, 235), and in Y’CBCR, reference black is (16, 128, 128), and reference white is (235, 128, 128). Values outside the nominal ranges are allowed, but typically they would be clamped for broadcast or for display. Values 0 and 255 are reserved as timing references, and may not contain color data. Rec. 709's 10-bit encoding uses nominal values four times those of the 8-bit encoding. Rec. 709's nominal ranges are the same as those defined in ITU Rec. 601.[1]
Primary chromaticities[edit]
Color space | White point | Primaries | ||||||
---|---|---|---|---|---|---|---|---|
xW | yW | xR | yR | xG | yG | xB | yB | |
ITU-R BT.709 | 0.3127 | 0.3290 | 0.64 | 0.33 | 0.30 | 0.60 | 0.15 | 0.06 |
Note that red and blue are the same as the EBU Tech 3213 primaries while green is halfway between EBU Tech 3213 and SMPTE C (two types of Rec.601). In coverage of the CIE 1931 color space the Rec. 709 color space (and the derivative sRGB color space) is almost identical to Rec. 601 and covers 35.9%.[3]
Standards Conversion[edit]
When converting between the various HD and SD formats, it would be correct to compensate for the differences in the primaries (e.g. between the Rec. 709, EBU Tech 3213, and SMPTE C primaries). In practice, this conversion is rarely performed because the difference is negligible in real-world scenes, except the ones with large patches of very saturated colors.[4][unreliable source?]
Luma coefficients[edit]
HDTV according to Rec. 709 forms luma (Y’) using R’G’B’ coefficients 0.2126, 0.7152, and 0.0722. This means that unlike Rec. 601, the coefficients match the primaries and white points, so luma corresponds more closely to luminance. Some experts feel that the advantages of correct matrix coefficients do not justify the change from Rec. 601 coefficients.[5]
Transfer characteristics[edit]
Rec. 709 specifies the OETF (opto electrical transfer function) of HDTV encoding in reference to the camera, known as camera gamma (sometimes indicated as 'scene-referred'[6] gamma). The Rec. 709 transfer function from the linear signal (luminance) to the nonlinear (voltage) is linear in the bottom part and then transfers to a power function for the rest of the range:[7]
Rec 709 Luts
The conversion to linear is as follows.
The power function of the majority of the gamma curve is 0.45, but because it is offset by the linear section the resulting equivalent gamma is more approximate to 0.50-0.53 (the inverse of which is approximately gamma 1.9-2.0 to convert back to linear).
Rec 709 Color Gamut
While Rec. 709 does not specify the display referred gamma, display gamma is discussed in EBU Tech 3320 and specified in ITU-R BT.1886 as a gamma of 2.4. This is a higher gamma than the 2.0 the math shown above would indicate, because the television system has been deliberately designed with an end-to-end system gamma of about 1.2, to provide compensation for the ‘dim surround’ effect. Therefore, the monitor gamma is not the inverse of the camera gamma. [8]
It is worth noting that Rec. 709 and sRGB share the same primary chromaticities and white point chromaticity; however, sRGB is explicitly output (display) referred with an equivalent gamma of 2.2.[9]
In typical production practice the encoding function of image sources is adjusted so that the final picture has the desired aesthetic look, as viewed on a reference monitor with a gamma of 2.4 (per ITU-R BT.1886) in a dim reference viewing environment (per ITU-R BT.2035).[10][11][12] Descargar logos 5 software biblico gratis para.
