Obtain Colorist Walter Volpatto’s DaVinci Resolve Characteristic Movie Node Construction
Hollywood colorist Walter Volpatto shares his DaVinci Resolve fastened node construction which he has developed whereas color grading function movies and TV collection equivalent to Star Wars: The Final Jedi, Dunkirk, Inexperienced Ebook, The Seaside Bum, Hustlers, Halfway, Homecoming (TV), The Hateful Eight, Interstellar and plenty of, many extra.
In actual fact Walter has over 133 color grading credit to his title on IMDB going again almost twenty years, so when Ravengrade.com shared a 15 minute video of Walter strolling by way of the fastened node construction that he used on Halfway, folks acquired excited.
Particularly provided that Walter has generously allowed Ravengrade members to obtain the node construction to make use of themselves!
Replace December 2022 – LowePost and sister web site Ravengrade.com have re-structured their content material so whereas Walter’s class was initially on LowePost I feel it’s now completely on Ravengrade.com. I’ve up to date this submit accordingly.
I’ve been an enormous fan of LowePost since they launched – principally as a result of they provide a consistently increasing array of fantastic post-production coaching on color grading, enhancing, visible results and extra, from a number of the industries high instructors {and professional} artists, all at a really reasonably priced worth of $79/yr which works out to about $6.5 a month.
On this earlier submit on studying high-end ending strategies in DaVinci Resolve Fusion I’ve mentioned a number of of their greatest programs and itemizing lots of the options of the remainder of their library, in order that’s a great place to look for more information.
Anyway, again to Walter, who by the best way works at Company3 in Los Angeles.
What’s a Fastened Node Construction and Why Ought to You Use One?
Whereas many colorists grade every shot from a clean slate, merely including nodes as they go to unravel particular issues or to use a constant look throughout a scene, a hard and fast node construction, like Walter’s, is added to each single shot within the venture earlier than any inventive color grading work begins.
Each time Walter begins a brand new shot the empty node construction is there ready for him.
I don’t wish to share an excessive amount of from the video as a result of it’s behind the LowePost paywall – and it’s simply one other nice motive to hitch LowePost as a paying member – however right here is simply one of many a number of causes Walter offers as to why you’d wish to work with a hard and fast node construction:
To me a node construction that’s fastened, it offers me self-discipline, so I don’t depart underwear round.
It offers me a way to open a shot 5 months later, take a look at what I did and I do know precisely why I did what I did, based mostly on the place my corrections are.
However having the complexity solved firstly, it implies that in a while you don’t have to consider it… It solves complexity. That’s what you need. You need to have the ability to give attention to the picture not give attention to the complexity once you’re color correcting with 5 folks within the room.

Within the video Walter walks by way of what each node does, how they work together, the place different layers of complexity could be contained and why working with a hard and fast node construction creates a strong and environment friendly color grading workflow that’s fairly indestructible.

The way to Import a .DRX file into DaVinci Resolve
When you’ve downloaded Walter’s .drx file from Ravengrade and are questioning get it into your venture, it’s quite simple.
Within the Colour web page open the Gallery pane and choose the PowerGrade 1 PowerGrades folder.
Proper click on within the area that claims ‘No Stills Created’ and choose “Import” and choose Walter’s .drx file.
Then to load the node construction onto your footage simply double click on the PowerGrade icon, or drag it to the node tree, or proper click on on the PowerGrade icon and select ‘Apply Grade’.
Computerized node renumbering in DaVinci Resolve 17
A brand new ‘function’ in DaVinci Resolve 17 is that it robotically re-numbers nodes in a tree, which breaks the fastened node tree workflow, particularly when rippling grades.
Hopefully this will probably be ‘resolved’ with an possibility to show this off in a future replace!
They’re quick these DaVinci Resolve builders!
Q&A with Colorist Walter Volpatto
Walter’s video has generated a whole lot of feedback and an honest variety of questions on the LowePost web site from different colorists, which Walter has taken the time to answer to, so I assumed I’d compile one of the best of these right here, to assist make much more sense of his fastened node construction.
Q – Are you ever utilizing digicam LUTS on node one?
A – By no means. I work in LOG area and my major look/LUT no matter, is within the timeline node.
Q – Do you usually begin work with a LUT (LOG – REC709) within the Timeline once you do the bottom grade?
A – LUT, Look, no matter is acceptable for the venture.
Q – In your trim nodes wouldn’t it’s simpler to make use of shared nodes?
A – Sure, if you would like, in fact. It’s simply time and I began when there was no shared nodes, and I’m used to it.
Q – Within the base node, do you usually use the printer mild or Curves? What do you like?
A – The fundamental concept is that the principle tonal mapping is completed on the Look degree: LUTs, curves, look no matter you need it to be.
On the node degree, you’re within the LOG of the digicam and printer lights simulate shut sufficient publicity and white stability as whether it is performed within the digicam. Due to this fact I exploit virtually completely Printerlights/Offset. Luma combine at 0. Acquire, if I want extra distinction.
Q – Why do you set the luma combine at 0? It doesn’t appear to have an effect on offset settings, solely LGG?
A – I like the mathematics with luma combine at 0, particularly once I want to make use of LGG controls (not often)
Humorous sufficient, in ACEScc/cct the logarithmic is such that an offset is absolutely mathematically equal to an publicity change.
Q – You stated that you just by no means should key pores and skin in case you’ve performed the stability and scene node proper. Are you able to please develop a bit on this? I’m studying coloration grading and I assumed when pushing a glance far it’s usually the behavior to key pores and skin?
A – After I do the stability of the shot, I take a look at the topic: normally the topic is an individual, therefore pores and skin tone.
I need the topic to be proper after publicity/stability. I don’t give a rat in regards to the background shadow not being completely black. If I’ve to vary the background shadow, that will probably be a secondary correction.
so: stability for the pores and skin/topic.
Secondary on the “secondary” elements of the picture.
Q – If I’m right you additionally make changes to the take a look at the “trim” node?
A – The concept is that on the trim node you’re doing a “scene” look (if any) or consumer trims: it isn’t unusual that after a scene is completed, that you must do a small publicity adjustment or make it hotter or total much less distinction or no matter. Deal with that as an total.
Q – After the first node, did I perceive accurately that you skip proper to the scene node, modify for the ‘look,’ and then return to work on the L-C-R and different nodes?
A – Roughly talking, sure, simply fundamental stability on the shot, then scene look, replicate the look to the scene, then matching the shot to the hero one.
Q – How do you go about (if even) node caching? Relying on the footage and grading system, playback after heavy noise discount specifically advantages from a cached node, which is why one may wish to put that as the primary operation on the tree.
A – I’ve plenty of area and I activate [smart caching]… normally it really works…
Q – Did you have got the possibility to mess around with Resolve 17? Any new instruments that piqued your curiosity?
A – The colour warp curiosity me, I performed with the Nobe plugin and I can do issues which might be tough in a standard state of affairs, however it’s extra for both restore a shot or create a glance…
Q – I’d like to know your method for utilizing a Movie Emulation LUT such because the Kodak 2383 offered in Resolve.
Do you utilize these LUTS at full opacity and do you do a Colour Area Rework to Cineon Log as an illustration with the intention to match the Gamma the LUT is designed for? Total how do you’re employed with such LUTS?
A – I do use them at full opacity, they’re designed to work in that means, however that you must rework the colour area LOG you have got in cineon log/709 primaries (that’s what the LUT is predicted for my understanding)
Q – Are you usually utilizing the usual LUTs in Resolve like Kodak or I heard you guys making your personal LUTs.
A – I used Resolve LUTs up to now, in addition to we do our personal LUTs from analytic information from movie.
At Company3 we’ve a proprietary system for movie profiling, up to now at fotokem I used the Truelight profiling system.
“Hustler” look was initially modelled to a Resolve movie LUT (modified to style).
Q – What’s the nice secret of luminance compression?
A – There is no such thing as a secret in “compressing the luminance” the concept is to construct a tonal curve that has a great “S” curve.
You wish to protect in a linear vogue the 7(ish) stops across the 18% gray, then gently push toe and shoulder to flatten the additional black and whites, the extra gently you do it, the softer the picture is, the more durable you do it, the extra distinction the ultimate picture has.
Q – When utilizing the build-in grain, do you set it on the ‘OFX’ place or earlier than / after the LUT or look on the timeline degree?
A – There’s the philosophical method and the sensible one.
If I wish to emulate damaging movie grain that modifies with the colour, it ought to be earlier than the stability node. No one does that basically, however it’s a thought.
If I wish to emulate as if the damaging was completely uncovered, then it is going to go earlier than the LUT/Look/major tonal mapping, normally for me that’s within the Timeline node earlier than the “look”.
If you wish to emulate print grain, it ought to go after the principle look.
However, all of that is purely tutorial: ALL of your materials will go by way of a compression go to have the ability to be seen: from theatrical (low) to streaming (technical time period is “shit-ton of it”).
So, the compression will assault the excessive frequency of your sign first, when you’ve got mild grain it is going to be gone, when you’ve got quite a bit, it would scale back the effectivity of the compression algorithm.
It’s a shedding battle.
I nonetheless prefer to see grain, Resolve OFX is sweet for me, and it’s primarily earlier than the principle LOOK within the timeline, if a shot or a scene wants extra, it is going to be within the photographs.
For a film the place two completely different worlds LOOK have been created (Bliss, on Amazon this coming February) the look and grain was moved on the group/scene degree, so every set of scene had its acceptable look. But it surely was a little bit of an odd ball… the truth that I didn’t use the group for something (not nook your self in case you don’t should) permit me to try this.
Q – Do you most work in YRGB or Colour Managed? Or perhaps ACEScct?
A – If the consumer has no choice, I work in YRGB and that i handle my very own coloration.
Q – I feel you normally work with a timeline set to Ari LogC in order that the instruments behave intently to how they behave with Cineon log movie scans? The place do you do the colour area rework for clips that aren’t in Ari LogC (different digicam sorts, VFX photographs and so on)?
In a pre-group node maybe? And the ultimate coloration area rework is on a timeline node most likely?
A – Both as DCTL on the media web page (most popular) or it relies upon.
If the shot is already in a LOG like I normally put it on the primary node, an OFX Colour Rework will act earlier than the primaries in a node (order of operations) subsequently your correction will nonetheless be in LogC.
If the shot wants some arduous rework, I’d put it within the second node, (repurposing) so i can coloration some within the authentic area after which rework it.
Q – What’s your workflow when you’ve got a DCP and a Rec.709 model to ship and also you’re not working coloration managed?
A – Utilizing OFX coloration area transforms, you possibly can just about do the identical math that’s is in RCM. It’s an identical…
So it’s a matter of realizing do it and the place to place it.
Q – How would you’re employed when there’s an ACES-workflow demanded? Or it’s a must to work with HDR and SDR deliverables?
A – The fundamental concept works in HDR/SDR/and ACES…. there will probably be acceptable transforms both at group degree, timeline degree or ODTs.
Q – Do you utilizing Calman to calibrate your displays?
A – At residence I exploit Gentle Phantasm, at work I’ve to ask the engineer group, however essentially the most distinction is ok by the probes we use, these are $20k…
Q – Do you utilize REC 709 Gamma 2.4 within the Timeline Colour Area in Resolve?
A – Sure REC.709/2.4 for TV, P3 D65/2.6 for cinema (normally), p3PQ for HDR.
Now, in case you’re speaking in regards to the setting within the Resolve coloration administration, that matches the logarithmic hero digicam (the log area I’m engaged on).
Q – Please make clear the way you propagate/ripple the modifications. The way in which you describe it appears a really quick operation: Carry out the change, choose the photographs to change, propagate. However because you don’t use pre/submit teams for this, neither shared nodes, how do you concretely copy and propagate the modifications that quick on so many photographs directly?
A – In the colour menu you have got two methods to propagate:
- ripple color change to present group
- ripple color modifications to chose clips
Q – You talked about utilizing Group Nodes as a spot for HDR trims and appears in case there isn’t a timeline look. May you elaborate extra on the node construction you’re utilizing in Teams and Timeline? I reckon you don’t use Pre-Group that a lot, however I’d be occupied with your Submit-Group trim node construction and your Timeline node construction.
A – I feel is simply too lengthy of a dialogue to be put in few sentences (I ought to do a color area/workflow with Lowepost…) however the common concepts are that both (or) within the timeline and POST teams, you wish to put two issues:
- the principle look of the film
- plus any transformation to adapt the grasp to a special spec, like HDR.
When you do a HDR mapping per scene, then it goes into the POST group, in case you do globally, then it goes in timeline.
