Every week, Frame.io Insider asks one in all our skilled contributors to share a tip, software, or method that they use on a regular basis and couldn’t dwell with out. This week, Rafael Bernabeu Parreño appears at how one can get higher data from Resolve’s Qualifier software.
Using colour areas to get higher Qualifier outcomes
One of probably the most missed instruments in Resolve is the RGB Qualifier. At first look, it’s a crude software with RGB choices providing a much less intuitive values in comparison with the HSL Qualifier,
But it doesn’t should be that manner. You can use a concatenation of Color Space Transforms to make choices within the colour area you need, as an alternative.
For instance, if we alter our area to Lab (CIE) and carry out a qualifier earlier than returning to RGB, the RGB qualifier will flip into one which makes use of the purple channel as L, inexperienced as a, and blue as b. With this methodology, we then carry out a personalized qualifier on this colour area, which isn’t achievable utilizing, for instance, the 3D qualifier.
Another use of touring between colour areas is just to search out parameters which can be simpler to entry in different areas. An instance of that is how saturation in logarithmic colour areas is usually a cumbersome parameter to pick, because it’s extremely compressed. This makes it laborious for the HSL qualifier is to cleanly choose these values.
A extra intuitive answer for that is to make use of a REC709/Linear colour area and gamma to separate the saturation values as a lot as attainable, making a cleaner choice.
REC709/Linear and Lab are simply a few choices accessible for colour choices in Resolve. However, I encourage you to discover and experiment with different colour areas and methods to search out clearer outcomes. These are the choices I exploit most frequently, however different fashions can even yield fascinating ends in a extra intuitive manner than the 3D qualifier.
