DaVinci Resolve: Node Structure Explained by Walter Volpatto

Summary:

This video features Senior Colorist Walter Volpatto discussing node structure in DaVinci Resolve [Image 0]. Key takeaways include:

The evolving role of a digital colorist, balancing creative look development with technical consistency [00:00:54]. Historically, film stock dictated the look, but now colorists craft artificial aesthetics [Image 6].
Node structure should effectively translate footage to the display, whether HDR or standard, often utilizing printer light emulation for versatility [00:01:39].
Volpatto organizes his node structure into modular blocks: balance, tweaks, and scene-level trims, to ensure consistency and flexibility [Image 14].
Film grain, when used, should be applied before visual effects to ensure proper blending and is becoming less common [00:05:33][Image 31].
Discussions also cover workflow examples and technical considerations, including color space transformations and managing different display targets, such as the process for "Dunkirk" [00:09:15][Image 44].

Introduction [00:00:00]

Senior Colorist Walter Volpatto presents on node structure in DaVinci Resolve [Image 0].
Walter Volpatto is a 15-year industry veteran whose credits include "Green Book," "Dunkirk," and "Star Wars: The Last Jedi" [Image 52].
A digital colorist is a craft that has changed over the years and is now more prevalent in the industry [00:00:37].

The job can be broken up into two aspects:
- Creation of the look and feel of the movie [Image 6].
- The technicality of making the movie seem like it was shot in one place and one time, ensuring scene coherence [Image 7].
In the past, film stock dictated the look, which was determined by the stock used for shooting and printing through a photochemical process, with very little being changed.
Today, colorists have more control to create artificial looks and achieve specific creative visions [Image 9].

Node structure should bring all the shooting on the set to the main display, whether it's HDR or standard.
Volpatto often uses printer light emulation for increased versatility in the shot.
He divides his node structure into blocks for a modular and consistent approach [Image 11]:
- Balance: Initial adjustments to get the shot in the ballpark [Image 12].
- Tweaks: Fine-tuning individual shots [Image 14].
- Scene Level Trims: Adjustments applied across an entire scene for consistency [Image 14][Image 26].
Examples of node graphs and DaVinci Resolve interface for balancing and tweaking are shown [Image 10][Image 13][Image 15][Image 18][Image 20][Image 21].

Node structure consistency: The structure can vary for each movie or specific projects [00:02:56].
Film grain placement [00:05:33]:
- It needs to be applied before Visual Effects (VFX) work, or it will be hard to blend [Image 31].
- Adding grain is becoming less common nowadays.
Understanding exposure and color science:
- Discussion on technical scales and 18% gray reference [00:06:50][Image 33].
- Illustrating color transformations using waveform monitors and curves in DaVinci Resolve [Image 34][Image 36][Image 39][Image 41].
Workflow example: Dunkirk [00:09:15]
- Walter Volpatto discusses the color post-production process for the film "Dunkirk" [Image 44].
- Explanations of display targets (e.g., 500 nits) and how different transforms are applied for various output formats [Image 47].
- Discussion of a comprehensive workflow diagram, including LUTs, VFX, and primary color correction [Image 49][Image 50].
