Audio Visualizer in DaVinci Resolve

hey guys CB super so today I'm gonna show you how to make this really neat audio visualizer it doesn't take too many nodes and it's really simple to do but in order to do it the way that I'm going to be doing it you're gonna need the reactor plug-in from the we suck less site and I've actually already done a video on where you can download this and how to install it and I'm gonna go ahead and link to that in the description and up in the cards so I'm not gonna go over that too much right now I'm gonna be using the suck less audio modifier actually show how to find that inside of that other video so go check that out first so with that being said I'm gonna go ahead and jump right into fusion and go ahead and start building out this audio visualizer now it's probably not a true audio visualizer in that I don't know how accurate the wavelengths are it's kind of a kind of just a like a really cool fake okay here we are inside of fusion I'm just going to bring this planet footage in and drop it over here on the left side I'm just gonna plug it right into my media out and everything that I build is just gonna be somewhere in between so there's a couple different ways to make the dashed line look you can either use a fast noise which is the way that I'm going to show you how to use it first or you can also use maybe something like a TV node or anything that makes horizontal or vertical lines that you can use as an alpha to mask out different parts of the line first thing I'm gonna do is I'm gonna go ahead and prep this fast noise so it looks like lines double click on the fast noise and I'm just gonna drop the detail down a little bit jump over to the color tab change the type from to color over to gradient you knee over to linear and I'm just gonna bring these two lines a little bit closer together now in the black I'm going to drop the Alpha all the way down I'm gonna bring these start and end points in a bit and you don't need to make them perfectly horizontal here you can actually come over to here and just type in 0.5 tab tab 0.5 enter click off somewhere and you'll notice that now it's a pretty good solid straight line now I may need to bring these a little bit closer because I have a little too much softness here in this line I want this be a nice defined line so the closer I can get them the better and now in order to make it into a bunch of lines I'm actually going to come down to the repeat section and just click on repeat and now you see I have a bunch of white lines which is exactly what I want and if I want to make these thinner like I do is come over to this second Y here on the end section and I can just move it up or down and make the lines thicker or thinner and I want these lines to be real thin because I want it to look kind of digital so that's probably good right there so the neat thing about this fast noise is you can actually mask out parts of the fast noise say if I was to bring in a circle you'll notice that it masks only this part of a perfect circle so say if I even if I wanted at the same size at this planet I could do that we're not going to be using an ellipse in order to do this effect we're actually just going to use a polyline but I actually want to see what this looks like on top of and I'm just gonna merge this drop this blend down just a little bit so I can see it a little bit better and I can tell already that I'm probably gonna need to offend these out even more just so they're real thin and I'm just gonna zoom in a little bit and since I'm gonna be using this planet background for my template I'm gonna go ahead and I'm gonna grab this polygon node tool wall clicked on the fast noise I'm gonna start on the planet and I'm just gonna bring it up close to the top of the screen doesn't have to be at the very top once I've made my two lines that's about all I'm gonna need and if I come over here to the modify only or shift m and now I can kind of move this a little bit just to make sure that it's properly straight now I don't want it to be a solid line I actually want to click off the solid and just give it a little bit of border width and this is kind of where you can kind of play with it and you can make it whatever you want it to look like personally I don't want this rounded top so I'm just gonna click on this one right here where it's flat it's gonna look a little bit better to me and I'm just gonna make this a little thinner kind of click off see what it looks like okay that's exactly what I was looking for now we can come back over to the merge and we can turn this blend all the way back up so it's nice and white and that's kind of the basis for this particular audio visualizer now you can you can make this however you want and you'll see that when we get to the polygon side we're actually gonna be animating this length here you'll notice whenever I move the length in and out it goes up and down just because I'm using the audio modifier on this to make it more automatic doesn't mean that you absolutely have to have the audio modifier you could just manually animate this length and you would get a very similar effect all right so now that we've set up our polygon and are fast noise I'm just gonna move these up just a little bit and I'm gonna add a duplicate node some shift space type in duplicate and I want this top one not the duplicate 3d and with the duplicate bring this in and for copies I find that right around 80 to 100 copies work so I'm just gonna go with 80 copies for now over here on angle I'm gonna go ahead and double click on this and since I want this to go all the way around this planet I'm gonna type in 360 for 360 degrees I'm gonna put in the division sign and I'm also gonna put 80 I want this to divide 360 degrees up 80 times because I want each one to be individually perfectly spaced from each other now again if I was to do this say I drop this down to 40 you'll notice that it covers about half of it so I would want to come back into the angle double click I could type in 360 divided by 40 and now it's gonna perfectly spaced them out if you didn't already know that that's just a quick tip to like get evenly spaced things around a circular object and so here's another thing if I come over to this polygon one let's say I add a transform in the center of this polygon well one thing you'll notice is that because I was clicked on the polygon it automatically decided it was gonna mask this transform I don't necessarily want to mask this transform what I want to do is actually gonna hold down the right mouse button bring it back in as an input and now I can use this transform node to transform where this mask is so if I wanted to bring it inward I could you'll notice that it's gonna bring all of the duplicate nodes inward you can do a lot of cool things with the duplicate nodes it's really really a powerful node it's also very computer intensive it will slow you down your fan will run like my fan is running right now you might not be able to hear what the audio denoise are on I can tell you that it definitely will run your compute a little bit hot you can decide where you want it exactly you can always mass this out after the fact I can see already that mine is just a little bit off I'll be able to fix that really easy by actually adding in another transform node after the duplicate because now from here all I got to do is just move it over a little bit rather than try to move this polygon over what that would do since I've already duplicated it so you notice if I come over to this transform here and I try to move this over to the right it's gonna start to skew these in a way that you don't really want it to and I don't know actually maybe you want to do that that looks kind of cool too but I'm not gonna do that for now so for what I'm doing it's just a little easier to transform an after-the-fact and you can move it around a little bit if you need to place it a little bit better job placement alright so here we are we've went ahead and we made the basis of this audio visualizer I'm actually gonna go back to having a tea because I think a tea looks a little bit better and I'm gonna come over to angle and I'm gonna type in 360 divided by 80 again alright so it looks pretty cool or if I want to come into this fast noise if I want to make these a little thinner I can if I want to make them a little thicker I can do that you have options here don't feel like just because once you do something you're completely locked into so like maybe I like that look I can do that it has kind of a digital look alright so we'll just leave it there for now and I'm gonna come over to this transform node just because it's gonna be a little bit computationally heavy if I have the media in the background and I'm gonna drop this down and I want to show you how this works over here in the polygon node if I adjust the length you'll see that the length comes inward vice-versa if I go out it goes all the way out in order to add this modifier I want to use the suck less audio modifier so I'm just gonna right click come with modify width and yours should be right here hopefully it's the audio wave click on that you notice that it's it turns red over here on your key frame and everything over here on the left or on the node panel turns red that's because we have to come in to the modifiers we have to tell it where to get the sample now the waveform is going to be wherever it is on your computer now it only works with certain types of files so make sure you watch that other video or you're already familiar with how to use this I know that it took me a little while to figure out that wasn't working on other even WAV files it would only works on a very specific type of wav file and that'll all be down there in the description right so I'm just gonna go to where my file is and I'm gonna come over here to I'm gonna use unsigned median I'm gonna need to adjust this offset some one alright so in the in this time offset I'm gonna come over here and I type in point four so once you adjust the time offset inside the duplicate node you're gonna start getting your waveform look depending on what your offset is set to so I'll let me come back over to this polygon node and let me go ahead adjust in the modifiers double click on the wave come over here to the modifier is right round I find right around point two probably works for what I'm doing right here you'll notice if I offset it too much it's just going to raise even higher takes a good while for this actually to initiate you'll notice that there's a lot of colors that are flashing down here that means that each one of these nodes is trying to process whatever I've changed and one thing that I've noticed is that this process takes a good while to render in fact it took me probably almost two hours to render it the first time I did it for the demo so I'm not gonna be rendering it or caching it in this video you're gonna have to do that on your own and have fun with that but that's pretty much it so just make sure that your amplitude offset isn't too high what worked for me in this specific scenario was right around point - I thought that gave me a really good look here it is that's pretty much it the only thing I did different is right after the transform node you can add either a background to color it or you can use something like my CB alpha glow and you can give it some glow you can also just colorize it you can use this however you want you can overlay it on top of other backgrounds let me drop this strong load down quite a bit you're definitely gonna need to play around with a couple different parameters and the parameters you're gonna want to play around with to get your individual effect is probably gonna be this time offset I found that 0.4 was a really good place to start going a little bit less than a little more but not going too crazy with it and then also on the fast noise playing around with the individual thickness of these lines so like I said it doesn't have to be a fast noise it could also be a TV node so let me go ahead and just delete this fast noise real quick and I'll bring in a TV node and I'll show you how to do this I'm just going to bring this in as a mask and then I'm gonna drop this background into this TV node now one thing you always have to do TV node is also a noise generator so what I usually do is I'll get rid of the power for the noise leave this bar strength alone come back over into this TV and then you play around with the with the actual scan lines so the more scan lines you give it the more spaced out they're gonna be if you bring it a little closer they're gonna be a little closer probably not a black background I'd probably bring this make it white and so now you're gonna get a very similar type of effect so if you come back in over to this polygon you can see the polygon is just in the lower portion but if you move along the line you'll see that it does in fact animate and so sometimes you can get some different looks just by changing this up a little bit so alright so that's how you can use either the TV node the only thing that it's duplicating is this one part so of course as it you know still drives it around 360 degrees you're gonna get your neat little digital line look and of course you can you can add power to it you can do whatever you want I mean you can you can even bring it back in here and you could remash the sin to here so if you wanted to add power you can add the power and what it's going to do is it's going to add the power only to the actual white part the color so I don't know if you can tell but it's definitely different it's it looks a little bit more deteriorated so play around with it you can even increase the size make it look real rough let me show you how you can do it without the audio modifier if we come over into this polygon instead of using the actual audio modifier I'm gonna go ahead and remove this audio and instead I'm gonna replace it with and modify do a perturb because I kind of like the way that perturb moves around and they come back in over to the modifiers so now if we look at the line you can see that it's going up and down it's uh it doesn't doesn't go up and down fast enough to where it would be kind of like music but what you can do is you can turn the strength down a little bit turn up the speed a little more maybe give it some wobble and now it's kind of looking like more like music and you can you can adjust the random seed you can adjust the value to make it go even higher to use the the full line alright and there you go it's animating although very slow but that's pretty much how you could do it if you didn't want to use the auto yo modifier for whatever reason you could probably fake this pretty well to the point where nobody would really be able to tell that it's not matching up with your music just by using that type of modifier and of course again it's still gonna take you a little while to render this out so when you do end up merging it back on just make sure if you want you can come over here to the merge and if it's perfectly matched up it's probably gonna be fine but you can always come over here to the apply mode and you could just not dissolve you can come over and you can just screen it on just to make sure that it's nice and bright and now you have like a really cool looking you know effect that didn't really require too much math or too much work alright and that's pretty much it so if you guys liked this video make sure to LIKE and subscribe hit that Bell notification and I'll see you guys in this one thanks [Music] you
