After each video cut there is a new LUT (for each individual scene).
A sunset needs different editing (lots of dark shadows) than filmed in the midday sun (hard shadows and lights). Or backlighting needs a different treatment than rainy weather.
You can't just correct with color editing, you can work out emotions. If you film in rainy weather, you can use desaturation to further emphasize the scene.
All this, if it's good, not exaggerated and kitschy, takes a lot of time. This is the only way to get the most out of every scene.
Quite a few movies, even some Hollywood productions are part of it, are unfortunately only cheaply colored. There is e.g. a blue veil over the whole picture. This colors the faces, the clothes, everything in the picture. The picture becomes a colored mud.
A good color grading shows clear defined colors and no color veil over the photo. Artistically everything is allowed, but people recognize cheap productions very quickly, even as a layman.
About the color space:
Every monitor model has its own color space.
It depends on the installed panel in the monitor.
On the Internet, the standard color space (smallest common color space) is sRGB (photo) or Rec. 709 (video).
But there are many more and also larger color spaces, e.g. Adobe-RGB or DCI-P3, etc.
The explanation and why there are so many different color spaces would go too far in this thread.
Because 95 percent of all monitors do not exactly display e.g. sRGB, there are deviations in color saturation and color values. One monitor model is at 77% sRGB coverage, the next one at 86%, another model shows far above sRGB, and so on.
Unfortunately, the color spaces are rarely hit exactly.
Samsung Smartphones are again often far above sRGB.
A monitor above sRGB shows too saturated colors, below sRGB too little saturated, roughly explained.
This results in between the monitors, often strong deviation in color saturation, you probably know all of them. The smartphone shows mostly too saturated colors, compared to a PC monitor.
This has mainly to do with color space, if it deviates strongly.
If all devices had e.g. exactly sRGB, there would be no big difference in color saturation.
You can calibrate it with a COLORIMETER, but it is a strong compromise in quality, the built-in panel is still at e.g. 88% sRGB coverage and can only be changed conditionally by software.
With a hardware calibrated monitor you can set and switch real sRGB or DCI-P3 as color space, has 100% color fidelity.
There are still color profiles, can be embedded in the photos. But to explain all that would go beyond the scope of this article.
I just think it's important to have heard it and why calibrating hardware and the lamps in your room makes a lot of sense. Otherwise it's a lot of gambling and a pity about the time spent on color grading.
Depending on the monitor it can work well or not.
