How different nodes work in DaVinci Resolve

so let's talk about nodes so the idea with nodes is they store different adjustments for the image so we have our first node here which we start out with we can come in and we can adjust the image with several different settings and then it just stored within this one node if we want to add additional adjustments we can add another node and then add even more adjustments to stack on top of our current adjustments so how this works is it starts out here this is our source this is the timeline so the file that's on our timeline it will come in here and then it'll come over to our first node it'll be processed by the first node and then it will follow the output and it'll go to wherever the output is in this case it's just to one second node and then this second node will process it and so so on and so forth throughout the whole node tree and then it'll finally make its way over to this little box which is the output that's where the final product of the whole node tree will then be located - so everything will go through the whole node tree to this output and then that's what will be displayed as the final output when you go to deliver the project back to our nodes here or now we're going to make an adjustment on the second node all of your nodes they can take any adjustments so you can do any of the adjustments that are down here you can do any of the adjustments that are in this second area and also over here you can use the key frame and you can keyframe adjustments depending on what that whatever it is that you're changing so this is number two and then down here we have corrector - we can do the little drop down and I'll have all the different parameters that we can keyframe which is everything the other thing that you can do with nodes is you can add a open effect into that node so if you were to add let's say a blur you know it would be added into this into here and then down here and the Oh effects we can keyframe it so like let's say we start the blur at zero and then a couple seconds in we can boost up that blur so now if we were to play this back it starts out as zero and as it works through its blurring more and so there you go that's how you keyframe all right so that's keyframing ofx now let's go into the different types of notes the only nodes are just nodes and coming into all of these different types of nodes all they are is the creation of a node which is like this over here and then it's being accompanied by something so we have our node and let's start out with a parallel node and what's going to happen is it's going to create another node and then it's going to add a parallel mixer what a parallel mixer is is it takes adjustments from all of the inputs and you can have multiple you can have more than one input you can continuously keep adding more parallel nodes in here but the idea is on the input of the parallel mixer it will take all of the node adjustments and it'll mix them together into a final output so if I was to take one node we'll have our fourth node here and let's just push everything blue and then on this node we'll take a in justment and we will put it right here and we'll push everything to yellow and then for this one we'll take everything and we will push everything purple okay let me come into this green one and we will just add a little more saturation so we can understand how this works and then we will add another note and as we can see what's happening here is it's mixing this actually might be a little difficult to see here let's move these down all right so what's happening here is each one of these nodes they're mixing so you're taking the purple with a blue and you're mixing it and you're just getting a darker purple taking the purple and the green yellowish and you're mixing it and you're getting this red and then mixing nice to you getting the color if I was to come up here and make a layer node right now I'm on five but if I was to make a layer node what would happen is it would make another node and then it would be accompanied by a layer mixer so let's talk about what a layer mixer is I'm just going to delete that quick and then just come into here this is one other thing that you can do between a parallel and a layer mixers you can right-click on it and you can morph it into the other so what you've seen when I switch this from a parallel mixer to a layer mixer is that they they work a little bit differently now now what happens is all of these stack on top of each other pretty much just like that whatever is down here will be the final thing to get stacked on top so when it starts out and puts this down and then the next one it will then put that one down and then it'll go to the next one and it'll put that one down on top and as you can see what will then happen is it's coming in you're setting an adjustment to just this the rest of this is just an alpha which means that it's transparent so there's no settings being there's nothing being added to that and then it's outputting that that that change so what's happening is I added the blue change but the blue change is getting layered on top which means because it's being layered instead of mixed together it'll just take this and it'll layer it on top and then as you can see here this is being laid on top of here and then this one is just underneath so let's go over why you would use parallel over a liar and then a liar over a pelo so if I was working on a project and I wanted to add some color effects in here and I was adding in my color effects right so I have my shot I really like this shot but I want to add something up here that's yellow a lot more yellow for right now I could add in another node and I could take this guy and put it up here and then I can take my highlight and I could push it I could push it towards yellow and what's happening now so what's happening here is it's going to take this blue shot and then since it's the next node and I'm going to add yellow in here now it's going to mix this blue with yellow and then we get this color here but let's say we want to add the yellow with the color that's that's coming out of here so what we would do is we would just add a parallel node so we'll delete this quick and we'll add a parallel and I did that with the keyboard if you come up here to nodes you can see all the shortcuts for all of these so now I have this node here and I want to add that same thing up here and add that in it's going to it's very subtle but because it's pulling from a different source it's going to mix just a little differently and they might not be coming from there they could be coming from other locations because if I want it to let's say now I have this grade going and I add another node but then I want his skin to look a little more natural so what I could do is I could make a layer node or a light a node with a layer mixer and I could say okay well this will overlap on top of there and they won't mix together what I could do here is I could take this the input for here and pull it from wherever it may be where he had like the skin tones looking the best you could pull it from there but I'm going to just pull it from the source and then what I could do is I come over to my qualifier and I could qualify his skin and then what will happen when I start to qualify his skin his skin will then become the mask so I'm looking at this now I could make this a little bit better come over we could because this is all white we could clean up the white a bit and then we could add this little bit in there and now we have his skin in the scene and it pulled a little bit of red over here which is fine if I didn't want that I could pull up a power window and then make the selection just inside of here so it'll be just this but it'll still only be the red so you could do something like that but it's a little more advanced but okay so now I have the skin tones from the source and they're laying over top of my collar great okay that looks good it looks very contrasting cuz they're very different if I wanted to make him feel like a little part of the scene a little bit more and not so contrast do you want to come to the color difference I could come into here and then I could key this and this is stating how much of an effect this will have as an adjustment so I could key this down so let's just say it was at one so we'll do the 60s so now we have remotely normal skin tones but they're slightly affected by the overall color grade so that's the difference between the layer and the parallel mixers and you can pull like I was saying you could pull sources from anywhere in your node tree so now let's go to some of the others our next one that we can do is add outside node how that node works is let's say I want it to affect this lower corner down here okay I wanted to affect this lower corner down here and I want it to let's do purple I wanted to add a purple into this corner here so we'll just shut this off now I have this purple in this corner but now I want to add something else outside of here and I don't want to affect here but I do want to affect up here what you can do is you could just add add outside and then what happens is it makes another node but then a connection is also accompanying the creation of that note and what this is is at all of these notes habit is this is the Alpha Channel and we're connecting the Alpha channel across to this node so it's saying okay all the transparent in here I want to copy that over here and then that's what my selection is for this node so that's how the outside node works so now let's go to splitter combiner so splitter combiner does a little bit more will split these up so I can show you so what splitter combiner does is it takes this signal signal meaning all the color values and it splits it up into a red green and blue Channel and then the combiner combines them all again to get a full color image so in these nodes we can affect what the red Channel what's happening with the red Channel and the easiest way to show this is if I come into here into node sizing and then I pan the red Channel you can see my red channel is being manipulated so I'm manipulating that red Channel and you can do kind of cool things in here what let's shift you know this one let's say negative 11 and then we can shift this channel 11 positive 11 now you have a color shift so you can do cool things like that the other thing that you can do is like all of the other nodes is you can add effects so you could take the red Channel and you could you know have that affected by one of these so let's let's go back and remove all of those let's do a zoom effect to the red Channel so I add the zoom effect into the red Channel I come over to settings although this one come over to settings then I can you know increase the strength of that zoom effect and you can see in here you can see here this is the red channel and this is what's happening to that red Channel and the other one is append a node and what this does is let's say you have a particular node so so far we have a lot of setting a lot of stuff happening in this but let's say for this node I wanted to add let's say a a lot onto here so I added a lot right to this node and let's say I wanted to add that to a bunch of other shots I could come in here and took clips if I had other shots and I could highlight all of those other shots that I want it and then have this node highlighted and then I could come up to here and a pen node and what would happen at the end of the node tree for all of those clips another node would be created and that node would have the same settings as the node that I had highlighted the final thing that I the final thing is all nodes you can have them work with colors in different ways so if you I'm working on this one node here if I right-click on it I can come down here to color space and I can switch between different color spaces so right now this is on LA B I have a video explaining how la B works but once you would make another node it would just default to RGB correctors and then all of these characters would just work the same as if it was just any normal node but you could come in and then you know switch it to all of the other color spaces so that's pretty much how nodes work within a node tree if you want it to this is currently on clip so all of these nodes will only affect this one clip if I want it to affect a whole timeline I could come up here and then it's a completely different node tree so if you were to group up a bunch of shots you would just highlight all of them right click on them and then add into new group you would pick the group click OK once you did that up here now you have other node trees that you can work on so I think that's everything on how nodes work if you have any questions leave them down in the comments I would say the best thing to do to get a good understanding of how these work is just play with it honestly with that being said my name is jr. thanks for watching [Music]
