Tips for Realistic VFX in Resolve (2024) - Blackmagic Fusion Visual Effects Compositing

in this video we're going to use a whole bunch of techniques to help you understand some deep more about V effects infusion if this is your very first day infusion check out this video instead and then come back here you know when you're ready let's go here's what we're going to be doing we're going to be making this comp is a lady on the subway with sunglasses on or is it damn no she's sleeping she's she's totally asleep she didn't have sunglasses on all right those are fake and we're going to take a look at how it's done and before anybody gets just crazy in the comments about the AI stuff you could just you could just do this with AI in certain situations maybe so but there are a ton of professional techniques involved here that you're still going to need to know even in a perfect AI world all right if you don't think so well why don't you just let me know through the magic of Internet comments just helps with the engagement let's move on first thing I'm going to do is go up to workspace and I'm going to turn off our show page navigation that'll just give us a little bit more room here in the noes and I'm just going to walk you through how I did this and then you can take these techniques and put them into your own stuff first thing we're going to do is start with our original footage and some shots are going to be easier than other shots the reason this shot is pretty easy is because she's not really turning her head she just has her head basically facing the camera she's just kind of doing this and so that makes it perfect for just a good old planer track so that's our first node the media in oh we're off to such a great start next we have a merge what are we merging do you say well let's go all the way to the top we're going to start with sunglasses PNG so this is just an image that I masked out the sunglasses and a couple things to notice we have these Reflections here on the rim which normally we would probably erase or clone or do something with but I didn't because it's going to be basically the same technique is I'm going to show you here in just like 5 Seconds the second part is we have these Reflections here in the glasses which sure looks nice as a still but if this is moving around and the reflection isn't moving that's a dead giveaway so what I did was took a couple of masks and applied them to a black background oh yes mask that beey and now looking at this I see one of them is fuzzy and one of them is not don't be like me kids be consistent but you know what it works fine and we're taking this and just merging it over the glasses with like a 85% blend all right so here's here's full here's a little bit I just did this just so we can get a little bit of lighting the curvature and everything even though it's not really realistic to do that you know it's not like totally the most realistic thing to do but it's going to work fine and then I roughly placed the glasses on her head now at this point if we were to move this around it's just it's not it's not exactly what we want it's just kind of stuck there so it's pretty good on this Frame but you know other frames be sucking just Su so what I did was I took this original footage and I brought up a tool called planer tracker like this and then I just kind of Drew a mask around her eyes like sort of where a VR headset would go right because this is virtual reality and what this does is it just selects a bunch of points inside of this shape and it tracks them all at once and so I went over to reference time and hit set and then tracked forward and it did some tracking went back to go and then tracked backward like this did some tracking and now we have her face tracked it's important to track as close as possible to where you're going to stick something to the track because that's going to be the most accurate movement right so that's why we track her eyes and not her mouth or something from there we can hit this little button create planer transform and what that'll do is make a little node called planer transform this holds all of the movement data that we tracked and it's just like a transform node but it's animated and so anything that we run through this effect is going to have that same movement okay so I took that planer transform and I put those glasses through the planer transform and then I took this transform and kind of moved the glasses to where they're supposed to be because it will kind of offset it once you apply the transform to it not a big deal just move it back and something to mention that I'm transforming this before it goes into the planer transform after the planer transform you don't want to scale things or move them around or anything like that or else it'll mess up the track if you don't believe me check this out let's put another transform there and let's just move this up like this and look what's happening oh it's crazy sauce it makes no sense I don't know why I'm talking like fog horn Leghorn but I am now who's respons I say who's responsible for this unwarranted attack on my person so we don't want to do that you always do your transforms and movement and scaling and all that stuff before your plan or transform that should be the last thing before you merge okay and so now it's doing a pretty good job you know it's it's all right we got the blacked out sunglasses it's stuck to the face pretty good but there are a few things to mention about this one which I already accidentally had turned on when I was explaining this but you want to turn on motion blur so you just select the node that you want to turn on the motion blur for go over to settings and here there's a tick boox for motion blur and check this out that's going to add motion blur as it moves which again if you don't have motion blur that's a dead giveaway so we put that motion blur on our plan to transform and now we have that moving around it's looking a little better another thing these glasses aren't quite the same color as everything else they kind of stand out they're a little bit too contrasty they're a little bit kind of pinkish compared to the background and you know the black on the headphones and that kind of thing and so we can use a color corrector to kind of blend that in a little better make it a little bit cooler change the contrast a little bit and that helps just kind of sit it in the image by the way if you're color correcting something and it has an alpha Channel like these glasses do make sure on your color corrector go over to options and click this pred post multiply checkbox if you don't look what it does oh you see that little shift it will sometimes mess with the whole image even though it doesn't really make any sense that it would do that but if you click this privide post multiply everything's going to be okay oh yes privide post multiply quite interesting then I was like I don't know this is still maybe just a little bit too sharp and so I added a little blur just to kind of diffuse this a little bit and then I was thinking that if she has sunglass glasses on there's going to be a little Shadow under these glasses like a little Shadow on her face so I just added a drop shadow this is just a plain old drop shadow and that really sells it it just puts a little bit of Shadow on her face and this is not advanced stuff this is just like the default drop shadow and it works pretty well I just tweaked the Drop Distance and the angle a little bit to be realistic and be kind of under the glasses and yeah works pretty well again all of that is getting ran through our transform which puts it roughly where it's supposed to be on her face and then the planer transform which actually sticks it to her face okay so now here's where we're at we have the sunglasses and she's moving back and forth and it looks pretty good if you're just going to do a quick meme or something like that you could totally just go with this like nobody's going to care if there's realistic Reflections and stuff in your two second shot it's fine and probably nobody's G to call you on and be like wait a minute I don't think those sunglasses are real most people aren't going to care or notice but if you do want to go the extra mile you can do something like get an image that's kind of roughly what you would think the environment would look like on you know behind the camera if you saw in the reflection of the sunglasses and do some color correction to it resize it by the way this is kind of stretched out but I don't really care that much just because it's in a reflection the right way to do this would be to probably crop this and resize it and that kind of thing but I was lazy I just resized it like this and it kind of squished it down down it's not going to matter that much just cuz it's a reflection you won't notice it very much and then again roughly putting this where it's supposed to be over her face like that and we can kind of just paste it over where the sunglasses are right so now we have this reflection roughly in place but we only want the reflection to show up in the lenses of the glasses right so what we can do is actually use our blackout for our lenses as a mask this is what's so cool about nodes is you can use this no node that's being merged over other stuff and you can take this and use it as a mask way down here for this merge and I'm just duplicating the planer transform and the transform that we had for the glasses and because this background is the same resolution 1920 x 1080 as our footage and everything we can apply that planer transform and it's going to perfectly stick that to the glasses and so we can use this as a mask for our reflection and look at that oh baby we have such a cool reflection now now these look like miror lenses and they're way too bright there's a bunch of things wrong with this but you get the idea right so we could take this blend down in our merge and kind of dial that into taste maybe it's something more like that maybe a little more subtle right and now we see that reflection and that's not a dead giveaway but one thing that does bother me a little bit if we were to zoom in here and let's just turn this up so we can see it a little better if I were to just line this up with the edge of my UI here check this out as I play this back this still in her glasses doesn't move at all which just ain't that realistic it would move a little bit because if we look back here we have sort of a shaky camera she's riding on the train the reflection and everything in the train is going up and down and so it's pretty safe to say that the reflection in her glasses would be moving around a little bit too it wouldn't just be like locked in the center what I did is went back to my planer tracker and I just tracked something that's kind of moving not as much as her face but just the background and I just made a little selection here just looking for a little bit of contrast here with these screws and just tracked that and made another planer transform which is right here and applied that to our still which makes it move with the train you get it you see so this is moving with the train let's just take this mask off and we see it's kind of moving with this window in the train and that's a close enough movement to be believable right and then we just mask that to her lenses and we have a little bit of Parallax here in her lenses it's moving around it's not just standing still then we take this reflection down and we've got a pretty realistic looking reflection in the glasses isn't that sweet so much fun and the last thing I did is if you have a still and you're just animating a still check this out as I go back and forth there's no real grain there's nothing there's no dancing grain here it might be hard to see on YouTube but here you can see there is dancing grain look at look at it go it's like a snowstorm all right that's what the footage actually looks like and so we want to put in some grain that looks similar on these elements that we put in afterwards there are a lot of ways to do this one cheap way to do that is just to add the grain over it right so we can take some film grain and this is just a plugin inside of resolve that just generates film grain and again it's like it's close enough it's not the exact grain but it's close enough if you just kind of like size it similarly and I just Ed this tracked glasses element as a mask for the film grain and now we have some dancing grain over the glasses as well as the background and then I can just turn off this grain only and now we have matched Grain on the glasses elements as well as the background and it's not a dead giveaway because without this grain this just looks too smooth and perfect and d a dead giveaway it's all about the details so our finished shot some fake sunglasses maybe just a little over the top on the uh reflection but I like it it's fun again if you were trying to be really great you'd probably get rid of these little Reflections here and either just black them out or do a similar thing where you would mask out this part and add a different kind of reflection on the edges oh boy that'd be a fun time but yeah that's how you add realistic sunglasses to somebody who does not have sunglasses hey if you're new here my name is Casey and I teach Fusion on the internet I even have a course that goes into all kinds of little essential tips for working in Fusion some of which we covered in this video but some of them are just really good to understand if you're going to be spending any time in Fusion it's called the fusion survival guide and if you click right here you can get it for free is my gift to you just cuz I think you're cool and I'm kind of bribing you to spend time with me because I think I think it would be really cool if we could hang out and talk about Fusion together you can get that Workshop right here and there's more visual effects goodness right here hey thanks you're the best have a have a sweet [Music] [Music] Day dead giveaway
