 Hello everybody welcome back to another Adobe After Effects CC 2021 tutorial this one I'm going to show you how to make lights flicker or blank or strobe or Illuminations flicker that type of thing guys. Let me show you what I'm talking about I will show you the original shot here this is just an image and Nothing at all is happening in it when I add on my next layer with all the effects on it And I hit space bar watch this It is blinking and flickering like it has an electrical source and again, this is just an image Let's do it. Let's start from scratch. Okay. I'm just gonna go ahead and delete this stuff But we're gonna start from zero. I'm gonna even delete the composite composition. So Here's where we are the first step is you want to bring in whatever video or image into your project panel The next step I'm just gonna drag and drop it in down here And this is going to create a new Composition with it with whatever the video or the image is in it the next step and this is an optional step But I just want to reduce the size of this is I'm gonna drag my playhead out to about five seconds or so I'm gonna drag this here the work area I'm just gonna drop it there and here's a thing I'm gonna do just gonna reduce the size I'm gonna go to composition Trim comp to work area. So we're just working with five seconds instead of 30 seconds of image or footage or whatever Okay Following along with me the next step is we are going to create a duplicate copy of this layer So this image or this video you go up to edit and you click on duplicate. That's it now We've got our duplicate layer now. It's time to apply the blur Want you want to go now to effects and presets For me it is on the right side if you do not see effects and presets panel Simply go to window. Make sure there's a check mark beside effects and presets Presto, let's go left click on effects and presets wherever it is for you and now in this search bar. We're gonna type in Gaussian When you do that, you're gonna get an option to go Gaussian blur select this one not the Obsolute legacy version Drag and drop the Gaussian blur onto the image or video Presto boom now you're gonna see under effect controls again If you don't see that make sure there is a check mark beside effects and presets and then you'll go into the effects controls Panel here is the Gaussian blur now for this. I'm going to jack the blur up and I'm gonna blur it Substantially, let's go to above. That's a bit too much. We want it to look. Well, let's see what let's see what 45 looks like Okay, you know what that's nice and blurry that looks good. Okay, so we've got a blurriness of 45 for this one Okay, good. Now the next step is we need to create a mask We only want the bright areas to be blurred. We don't want the rest of the image blurred So what we want to do is making sure you're on the top layer still head up here and grab the pen tool Let's click on it and we're just gonna draw a very quick mask and it doesn't have to be extra accurate And the reason why is because Excuse me. We're going to be feathering it so we don't need to be super accurate So I'm gonna go to here. I'm gonna go to here I'm just gonna pull on that a bit to create a little bit of a bend and a pull on that to create a bit of a bend I'm gonna click here create a bit of a blend again. This does not have to be Perfectly accurate. I'm gonna create a bit. Oh, that's a bit much Whatever alright something like that. I'm a little too far out, but that's okay There we go, and then I'm gonna go to here and a pull on it pull a bit of a blend and again This doesn't need to be all that accurate just nice and close and Go to here and we'll go to here and then we'll go to here here Here and zip it up. There we go We have added the mask and I made sure that on the last point when I clicked on it There was a little oh so that it means that it closes now go to the Second layer here the top layer click on that triangle Click on the one on beside masks and when you do that you're gonna see mask one This is good news. What we want to do now is we want to increase the feather considerably This basically blurs the outside edge and the inside edge, and it just sort of makes it sort of shade and Less stark contrast between outside and inside. So it just feathers the edges I guess that's why the word is feather. So we've increased the feather to a hundred pixels Excellent the next step on the top layer. We're going to switch the mode now If you do not see mode don't panic because there's a chance that you will see this You want to go down here and expand or collapse the transfer controls paint If you don't see the mode left click on that little button here, and now you will under mode Click on it, and we're gonna drop it down from regular. We're gonna change that to screen all the sudden It is brighter. Let there be light Excellent. Let's keep going. I'm gonna click out of this one here I am going to go back to my effects and presets panel And now it's time to add in a little bit of blur The best way to do that in my opinion is to go to the top here under animation presets Click on that and then click on behaviors Sort of scroll down to the bottom ish area, and you're gonna see a few options The one we want is opacity flash random Left click on that and drag and drop that on top of the light bulb mask When you do that, you're gonna see something cool I'm gonna go ahead and hit spacebar, and all of a sudden we have a very subtle But very noticeable Flash now that's a good chance that that is all you need to do and if that's it you can click off this video now We have solved your problem. We've got some flashing and some strobing, but it is quite subtle, and it's not very fast So making sure we're selected on the top layer. We're gonna go to effect controls again Under opacity flash you'll see it in the effect controls here You have the chance of flashing and flashed nervousness. What is this a? Flash went to a first dance or something or at the prom whatever the chance of flashing I am going to increase it to about 70% because I want it to flash frequently Partly because that's kind of the effect I'm going for and be because I want it to be more noticeable for you And more importantly, I'm going to increase the flashed nervousness from a standard of 50 I'm going to jack it up to about 150 sir. Let's go about 150 something like that so that it happens a little bit more often Let's go ahead and now see what we've got him a left click outside of it hit spacebar. It is nervous That's right guys. We have a jittery nice perfect strobe flash If you want to go even further down the rabbit hole and again This might be not necessary for you if not click off leave me a like I'd like that. Thank you We can add one more thing in here and what you can do is you can go to stylize down here and Under stylize we're going to add one more effect the one we are looking for is strobe light left click on strobe light and Also drop it on top there This is going to make it a little weird looking because in this case here You'll see when I hit spacebar It's flashing but it's flashing and the color is wrong as you can see here It's bright white LED light and this one is an older lamp. So what we're going to do is we're going to go to strobe color We're going to left click here And we're going to click on this little eyedropper and we're going to take one of the yellow colors like something out here Like an orange yellow there we go And I've left clicked on it now the strobe color is that color now when I hit spacebar It looks a little bit more believable, but it's a bit too much So the last thing I will do is I will blend this in with the original a little bit and now let's see something like 47 Let's go 47% now let's hit spacebar and watch what we got We have a flickering light. We did it out of nothing. That's all there is to it guys Thanks for watching. I'll be back soon with some more tutorials. Cheers
