Davinci Resolve 19 Color Page New Features

UltraNR is a noise reduction feature powered by the DaVinci Neural Engine within the Color page’s spatial noise reduction palette. It significantly reduces digital noise in frames while preserving image clarity. When combined with temporal noise reduction, it becomes even more effective in reducing noise in moving images.

This tool enhances the image noise reduction process by offering a more intuitive, faster, and easier method. Previously, in the industry, there was the Neat Video plugin, which automatically applied noise reduction after analyzing the footage.

To apply UltraNR:

1. Navigate to the Spatial NR tab and select the Ultra NR processing mode.
2. A new tab called Noise Profile it’s now available
3. Simply click the analyze button to initiate the analysis. DaVinci Resolve will automatically analyze the footage using the Neural Engine and calculate the luma and chroma values based on the selected area of interest. 
4. If needed, adjust the analysis square to perform a new analysis.

Over time, professionals have increasingly turned to node trees to maintain consistency and efficiency when applying effects across different shots. With this evolution, massive node trees are becoming more common. However, the complexity of nodes can sometimes be a distraction for those who struggle to maintain discipline and consistency across their work. Therefore, in order to break tasks down into manageable steps, I believe that Node Stack Layers have emerged to maintain the complexity of node trees while visually simplifying the process, allowing for a quick and easy overview of various color grading processes or stages.
Primary adjustments, secondary corrections, power windows, qualifiers, texture, and more can now be compartmentalized into multiple layers, up to 4.
For me, this will be an excellent tool to organize everything in a way that maintains consistency and breaks down my work into manageable steps. Let me provide an example of how I could use this function:

Layer 1: Primary Corrections
Layer 2: Secondary Corrections
Layer 3: Power Windows
Layer 4:Texture

The main question is: Is the signal from the green box coming directly from the original footage or from the previous stack? This is a fundamental question that needs to be answered and tested because hue and saturation qualifications will yield complementary values, which can make selection easier or more difficult.
Considering that certain actions to achieve certain results must follow a specific order, and from my analysis, the same function as the serial node is applied between stacks one after the other.

Furthermore, a key consideration is that as we complete grading, if we deactivate the stack layers in the project settings, the grading within those stack layers will no longer be applied. However, the great advantage is that Davinci Resolve, even when not displaying the stack layers, retains the stored information in case we want to reactivate them.
In my opinion, this will also be a great advantage for developing versions and looks in the early stages of the color grading process. By applying 4 different looks in each stack and activating/deactivating the stacks as needed, we can quickly analyze various types of looks.

Layer 1: Rec 709 Base Grade
Layer 2: Saturated
Layer 3: Bleach Bypass
Layer 4: Film Emultation

Copying and Using Apply Grade Between Clips: In my opinion, it becomes a bit more confusing and difficult. Let me explain:

Copy and Paste with Middle Mouse Click – I have always used this tool extensively to copy the grading from one clip to another or even to select all and copy the same grading. Now I find this task a bit more challenging because when using the middle mouse click to copy the grade and having the stack layers activated, it only copies from the active layer and does not copy the entire grading that the clip has and its respective layers. For me, this is not the best process because it forces me to first Grab Still of the same clip, then later select Apply Grade, which then applies all the layers.

Let me give an example with two ARRI LOG clips. The stack layers configuration is as follows:

My first clip: Essentially, my clip will have a Cyan grading ( Blue + Green )

Now let’s copy the grading from one clip to another. Both stack layers have adjustments. In Clip Number 2, I have the “Add Green” stack layer selected, and I click with the middle mouse button.

My second clip, which should have copied everything and turned Cyan, turned Green instead. It only copied the Stack Layer that was activated. Stack Layer ” Add Green”.

In my view, this doesn’t make much sense because it makes the process more difficult. Instead of one click to copy the grading from one to the other, now you have to make more clicks based on the number of stack layers.

The same thing does not happen if we use the “Apply Grade” option within the timeline or in the gallery.

Blackmagic, please add a checkbox “Copy and Paste All Stack Layers” for us to use with the middle mouse button. This example highlights the issue, but with footage and small changes, sometimes it will be very difficult to tell if the change has been applied or not. Our brains are already programmed and accustomed to the middle mouse click applying the grading to the entire clip.
