Make a better Glow in After Effects

The built in “Glow” effect in After Effects has a whole bunch of limitations that make it a pain to use when you want to really dial in a look. In this tutorial, Joey will show you how to build a way better glow effect than what After Effects has to offer you right out of the box. By the end of this lesson you'll be able to build your own glows from scratch. While this may sound difficult you’ll see that it’s really simple and powerful once you get the hang of it.

    00:00:11,404- Hey there Joey here for School of Motion.
    00:00:13,519And in this lesson we'll be taking a look
    00:00:15,449at how to build a better glow effect
    00:00:17,309than what After Effects has to offer us
    00:00:18,941right out of the box.
    00:00:20,320The built in glow effect that comes with After Effects
    00:00:22,775is really clunky to use and limits
    00:00:24,482the looks you can achieve.
    00:00:26,227The way that I'm gonna show you how to build a glow effect
    00:00:29,042will give you a lot more flexibility
    00:00:31,085to really dial in the look you're going for.

    00:00:35,752so you can grab the project files from this lesson
    00:00:37,628as well as assets from other lessons on the site.
    00:00:40,642Now let's jump in.
    00:00:43,190So I have a comp setup here and there's one layer
    00:00:47,441in it which is this Photoshop file.
    00:00:50,395And I picked this Photoshop file
    00:00:52,279because it has a lot of contrast in it.
    00:00:55,322And when you have images with lots of contrast,
    00:00:59,420especially when you shoot these things on film,
    00:01:02,580a lot of times you'll get natural glows,
    00:01:04,830and that's why compositors and motion graphics artists
    00:01:08,101add glows a lot to these types of images.
    00:01:11,635I also chose this image because it's very very saturated.
    00:01:15,251And when you add glows to images like this
    00:01:17,897there's a lot of problems you can run into.
    00:01:20,110And I'm gonna show you how to deal with those
    00:01:21,789and some better ways and cool effects
    00:01:24,580you can get using this technique.
    00:01:26,958So to start with I'm gonna show you
    00:01:28,381the way most people go about adding a glow.
    00:01:31,118And when I say most people I mean
    00:01:33,435most beginners that I've worked with and other freelancers
    00:01:36,754and people who don't know how to do this new technique
    00:01:39,156which I wish everyone knew how to do.
    00:01:41,636So what I'm gonna do is go up to Effect,
    00:01:45,801and I'm just gonna add Stylize, Glow.
    00:01:50,179Alright, so there you go, there's your glow.
    00:01:52,925Now the first thing I don't like about the glow effect
    00:01:55,604is that it's not that easy
    00:01:58,807to dial in the look you want.
    00:02:01,269So,
    00:02:03,067what the settings are called on this glow effect
    00:02:06,265are not that intuitive.
    00:02:07,975Now I know what they are because
    00:02:09,553I've used this many many times.
    00:02:12,844So let's say that I want a little less glow here,
    00:02:16,766so I would bring down the intensity, right?
    00:02:21,533But now I want the glow to come out further
    00:02:23,290so I would increase the radius.
    00:02:26,247But now I'm noticing that there are things glowing
    00:02:28,732that I don't want like this area here,
    00:02:31,247this white area on this red pyramid.
    00:02:33,375So I figured out, okay well maybe that's the threshold,
    00:02:37,130the threshold's set too low, so I need to raise that.
    00:02:40,190So I'm gonna raise that up.
    00:02:41,490But in doing that I've actually lowered
    00:02:42,993the Intensity as well so now I need to crank that back up.
    00:02:45,879So it's this constant dance to get the look you want.
    00:02:49,722And then at the end of it, let's say I
    00:02:51,740want the red pyramid to glow more than the green pyramid
    00:02:55,251I can't do that unless I maybe break this up into layers
    00:02:59,460or create some adjustment layers
    00:03:02,007but then that creates its own problems.
    00:03:04,978And then there's not that many settings
    00:03:07,961as to what I can do with these colors.
    00:03:09,946Let's say I wanted to de-saturate these colors
    00:03:13,746well there's really no good way to do that.
    00:03:16,521So
    00:03:18,049what I'm gonna do is delete this
    00:03:20,302and I'm gonna show you one more problem with the glow effect
    00:03:23,300which is actually a bigger problem in my opinion.
    00:03:26,219If I add the glow effect to this layer,
    00:03:29,176and all I've done is created a quick little comp
    00:03:30,920to show you guys with just a shape layer
    00:03:33,283in it on a gray background.
    00:03:35,638I'm gonna add the glow effect to this layer.
    00:03:38,524You'll see now it's glowing.
    00:03:40,861And we can control the radius and everything we can before.
    00:03:44,603Now let's say we wanted to animate this glow from off to on.
    00:03:50,598Well if I just bring the intensity down to zero,
    00:03:54,851look at this, we get this little buddy,
    00:03:57,541this little black halo around our layer that we don't want.
    00:04:02,032And to get rid of that we also have to bring
    00:04:04,132the radius down to zero.
    00:04:06,680So when you animate this on you're not just animating
    00:04:09,956a glow on you're also having to shrink and grow the glow.
    00:04:14,266So it's not a great effect to animate either.
    00:04:18,094And you get this weird, I really don't
    00:04:20,199understand why you get this black halo
    00:04:22,666and it's annoyed me for years.
    00:04:24,207But that's one of the reasons I don't
    00:04:25,493use this glow effect anymore.
    00:04:28,097So let me now show you the way
    00:04:30,119that I usually make glows and hopefully
    00:04:32,944you guys will start to get some cool ideas
    00:04:36,536about how you could use this technique
    00:04:38,342to create new glows and get cool effects
    00:04:41,213that wouldn't be possible any other way.
    00:04:46,108So first I want you to understand what a glow is.
    00:04:49,622And the way I think about it all a glow really is,
    00:04:54,309and I just duplicated this layer
    00:04:56,110just so I can show you guys,
    00:04:58,644all a glow is is a blurred version.
    00:05:01,661So I'm gonna add a Fast Blur to this layer.
    00:05:04,869It's a blurred version of a layer added over it.
    00:05:09,710That's it, see how it now looks like it's glowing?
    00:05:12,048Now that's very simplified version of it
    00:05:15,268but in essence that's what a glow is.
    00:05:17,048It's sort of the image that has bright areas, blurred,
    00:05:21,649and then that blurred copy of the image
    00:05:24,873is added or screened,
    00:05:29,518or maybe burned,
    00:05:30,884or dodged, over the image,
    00:05:32,724depending on the effect you're going for.
    00:05:35,517So what's great about thinking of glows this way,
    00:05:39,140I'm gonna delete this layer for a second,
    00:05:41,439what's great about this is that you can think of a glow
    00:05:44,100as its own layer.
    00:05:45,873And you can have total control over that layer
    00:05:49,243including the brightness and darkness of that layer,
    00:05:52,712how much that layer's blurred,
    00:05:54,353how much of that layer you even wanna show,
    00:05:56,553the saturation of that layer.
    00:05:58,377So let's say that we want only the red pyramid
    00:06:02,625to have a glow on it, and we only want
    00:06:05,066the top of the red pyramid to have a glow,
    00:06:07,523and we don't want this white part to glow,
    00:06:09,356only this red part.
    00:06:11,310So with the glow effect that would be a lot trickier,
    00:06:15,260with this technique it's actually pretty easy.
    00:06:16,880So what we're gonna do is we're gonna make
    00:06:18,774a duplicate of this layer, Command-D.
    00:06:23,072And I'm going to add a Levels effect.
    00:06:29,631Now when you make something glow
    00:06:33,634and generally when I make glows I use the Add mode
    00:06:37,927on the glow layer 'cause you get that
    00:06:40,348nice bright popping effect.
    00:06:43,371I'm gonna undo that.
    00:06:45,240So when you add something if your glow layer
    00:06:48,263has any black areas in it
    00:06:51,148that part of your glow layer
    00:06:53,441will not show up, only the bright areas show up.
    00:06:56,288So I use that to my advantage by using the Levels effect
    00:06:59,385to crush the blacks to make everything disappear
    00:07:03,535that I don't want to show up, alright?
    00:07:06,564And when I say crush the blacks
    00:07:07,853that's what this arrow does on the Levels effect.
    00:07:11,281It brings everything to black
    00:07:15,058to the left of that arrow, okay?
    00:07:18,118Now
    00:07:19,312you might think that I wanna crush those blacks
    00:07:21,277all the way til only the red's showing up.
    00:07:23,335I don't need to do that,
    00:07:25,211I just need to make this little arrow,
    00:07:27,005this little white arrow that was within
    00:07:29,137the red pyramid go away.
    00:07:31,894So now that that is pretty much gone
    00:07:35,197now I'm gonna add the Fast Blur effect
    00:07:39,833to this layer.
    00:07:40,666I'm gonna have Repeat Edge Pixels turned on.
    00:07:42,614And I'm just gonna blur a little bit alright?
    00:07:45,292And you can see that when I blur it
    00:07:47,946it starts to crunch in a little bit.
    00:07:51,068So I need to un-crush those blacks just a little bit.
    00:07:55,453And then you can even push the whites
    00:07:57,100a little hotter if you want to.
    00:08:00,866Until I actually turn this into a glow
    00:08:02,956I don't know what it's really gonna look like
    00:08:04,291so I'm just gonna leave it there.
    00:08:07,087And now if I set this to Add Mode.
    00:08:11,365Now you will see something strange has happened here.
    00:08:14,765I have basically made my comp very dark.
    00:08:18,043Now the reason for that is because we are in 32-bit mode.
    00:08:22,512Pretty much all the time now I work in 32-bit mode.
    00:08:25,697It's a better way to composite,
    00:08:28,490especially things like glows,
    00:08:31,287they work a lot better in 32-bit mode
    00:08:33,602and there's some really complicated reasons why,
    00:08:35,973I won't get into those now.
    00:08:38,184But I'll show you how to fix this.
    00:08:40,645And just to prove to that this is actually
    00:08:42,270what's going on if I switch to 8-bit mode my glow works now.
    00:08:47,151If I turn this layer off and then turn it back on
    00:08:49,396you can see I now have a glow.
    00:08:51,875But in 32-bit mode I get this strange effect here.
    00:08:55,640The way to fix that is you need to clip your blacks.
    00:09:02,817The short version of what's happening is
    00:09:05,536when I crush these blacks I'm actually
    00:09:07,442creating black levels that are less than zero.
    00:09:12,645So when I add those black levels to the image underneath it
    00:09:17,521I'm actually darkening the image even though I'm adding.
    00:09:20,609It's like I'm adding a negative number,
    00:09:22,316think of it that way.
    00:09:23,649So in the Levels effect you can clip,
    00:09:26,017where it says here Clip To Output Black,
    00:09:28,935right now it's off, it's off by default,
    00:09:30,713I'm just gonna turn that on, alright?
    00:09:32,562So now we get all the glory
    00:09:35,641of 32-bit glow compositing
    00:09:39,065but our blacks are not going to subtract
    00:09:42,437if we crush them a lot, okay?
    00:09:45,024So now you can see this glow is pretty subtle right now.
    00:09:48,858It's not doing a lot.
    00:09:50,488And I'm just going to quickly rename this layer
    00:09:55,380Red Glow so I can keep track.
    00:09:58,714So you can see what happens if I crush
    00:10:01,946the blacks more or less,
    00:10:05,249you can see now this is essentially
    00:10:08,571the threshold setting of the Glow effect.
    00:10:13,170It's how bright does the image have to be
    00:10:15,193before it actually glows, right?
    00:10:17,394Think of it that way.
    00:10:18,559So doing it this way's better
    00:10:20,543because if I solo this layer I can actually
    00:10:23,035get a visual representation of the parts
    00:10:26,227of my image that are going to glow.
    00:10:27,890It makes it a lot easier to figure out
    00:10:29,545where things are that need to glow.
    00:10:33,247This Fast Blur is now the radius of my glow.
    00:10:37,524So if I just want a slight glow I might just keep
    00:10:40,271that around there and now if I push the white levels
    00:10:44,516that's the intensity of the glow, alright?
    00:10:50,752Now my favorite part about doing it this way
    00:10:52,769is now I can draw a mask on this layer.
    00:10:55,781So I'm gonna hit G, bring up the pen tool.
    00:10:58,388And I'm just gonna draw a mask
    00:11:00,359just around the top of this pyramid.
    00:11:02,946And I'm gonna hit F so I can feather that mask.
    00:11:06,032So now, I'll maybe need to feather that a little more,
    00:11:08,754now I have this nice glow just on the top
    00:11:10,985of this red pyramid, alright.
    00:11:14,110Now
    00:11:15,514it's starting to look a little too over-saturated to me.
    00:11:20,134That's pretty common with glows
    00:11:22,214because you're also increasing the saturation
    00:11:25,475of the image underneath the glow layer
    00:11:27,767when you add the color of the glow to it.
    00:11:29,974So,
    00:11:31,335the best way to deal with that is to de-saturate the glow.
    00:11:35,289So I'm gonna solo the glow layer so we can just see this.
    00:11:38,527This is just the glowing part of the red pyramid.
    00:11:41,099I'm gonna add an effect to this.
    00:11:44,769Color Correction, Hue Saturation.
    00:11:47,584And now
    00:11:49,503I can de-saturate the glow if I want to,
    00:11:51,720or I can add more saturation if you want to.
    00:11:55,065So if we look at this in context
    00:11:57,730if I bring down the saturation,
    00:11:59,752you can see now if I bring it down too much
    00:12:01,859it starts to turn it white and kinda de-saturate
    00:12:05,590the image underneath it which could be a cool look,
    00:12:09,171it almost starts to look
    00:12:12,139like a bleach bypass or something like that.
    00:12:14,977I don't want to do that, I just want to bring it
    00:12:16,901down a little bit so it's not such
    00:12:18,611a screaming red color.
    00:12:21,299That's starting to feel pretty good.
    00:12:22,632Now I feel like I wanna see a little bit more of that glow
    00:12:25,097so I'm gonna blur it a little bit more.
    00:12:29,014And I'm just gonna push those whites
    00:12:30,424a little hotter so we get a little more glow.
    00:12:32,333That feels pretty good to me,
    00:12:33,660I'm actually, I'm digging that.
    00:12:35,855And you can see if I turn that off,
    00:12:38,226turn it on, it's just a nice little glow hair right there.
    00:12:42,981And if this was animated, this is just a still,
    00:12:45,227but if it was animated if I animated this mask
    00:12:49,253then this glow would only be on this pyramid,
    00:12:51,822I could totally control it, alright?
    00:12:53,978So now I'm gonna do the green pyramid.
    00:12:58,102So what I'm gonna do is duplicate my Red Glow layer.
    00:13:01,169I'm gonna rename it Green Glow,
    00:13:04,752and I'm just gonna move the mask over.
    00:13:07,863And let's say we want a little bit more
    00:13:09,631of that green layer to glow, alright?
    00:13:13,352So let's solo that green layer,
    00:13:14,997we see this is now the piece of the image that's glowing.
    00:13:19,428Now this green layer
    00:13:22,292feels a lot more saturated to me than this red layer,
    00:13:26,008and it could just be that the color
    00:13:27,901of the pyramid to begin with was more saturated.
    00:13:30,239So I'm just gonna, on this Green Glow layer,
    00:13:33,655I'm gonna use this Hue Saturation
    00:13:35,380and bring that saturation down even more.
    00:13:38,744All the way to negative 100, alright?
    00:13:41,434Now just to show you guys some other cool things
    00:13:43,319you can do with this,
    00:13:44,460if I bring this saturation back up,
    00:13:47,149now that this is own its own layer
    00:13:48,662I could actually affect the hue of the glow too
    00:13:51,564so if I want I could push that glow more blue.
    00:13:57,070And you can see the effect you're getting,
    00:13:58,845I could push the saturation on it,
    00:14:01,539and then come back up here
    00:14:02,874and bring the whites back down a little bit.
    00:14:05,371And you can get this kind of cool glow to it, right?
    00:14:08,581It's a bluer color than the actual pyramid underneath it.
    00:14:13,159And because I have total control over this
    00:14:15,067I'm gonna solo this one more time,
    00:14:18,165if this feels too bright to me I can also
    00:14:19,793mess with this bottom set of arrows here
    00:14:23,874which is basically the output level
    00:14:27,489of the Levels effect.
    00:14:29,189This is the input level, this is the output level.
    00:14:32,331If I bring the white output down
    00:14:33,799I'm darkening the white level.
    00:14:36,403So if we un-solo that I can control
    00:14:40,176how bright that glow is on its way out too.
    00:14:45,564So now I have my red glow, I have my green glow,
    00:14:49,110and they're set very differently
    00:14:52,094but I can totally control each one.
    00:14:55,331So now let's do the blue pyramid.
    00:14:57,204So I'm gonna duplicate the green layer.
    00:15:00,820I'm gonna move the mask over so I can see it on the blue.
    00:15:05,284Now let's say for the blue one I don't want the hue,
    00:15:08,945and I'm gonna rename this Blue Glow.
    00:15:12,090I don't want the hue to shift on this one
    00:15:14,149so I'm gonna set the hue back to zero,
    00:15:16,967so now it's basically, it's a blue glow.
    00:15:22,550I do want to de-saturate a little bit.
    00:15:26,377I want it to be a little bit brighter
    00:15:28,287so I'm gonna increase the white output,
    00:15:30,484I'm gonna bring the whites, I'm gonna bring
    00:15:32,928the white input back in a little bit
    00:15:35,541so it brightens everything, okay?
    00:15:39,664And I wanna try a different blur on this pyramid.
    00:15:44,191So if I turn this fast blur off and we solo this layer.
    00:15:47,978So this is the part of the blue pyramid
    00:15:51,523that we have isolated to glow.
    00:15:53,638And we did that by using the levels,
    00:15:55,278here's the RAW image, actually here's the RAW image.
    00:15:59,002And remember we used levels to crush these blacks
    00:16:02,986so we only have this part that's gonna glow,
    00:16:06,212and then we used hue and saturation
    00:16:08,038to bring the color saturation down
    00:16:09,820so the glow doesn't blow out the color.
    00:16:13,390But we have all these other blurs in After Effects
    00:16:16,452that we can use and they all do different things.
    00:16:19,599And you can play with 'em and I would suggest you do that
    00:16:23,938because you can get really cool effects,
    00:16:27,359you actually can recreate a lot of very expensive plugins
    00:16:31,379that you can spend hundreds of dollars on
    00:16:33,739by doing this technique and combining a few different blurs.
    00:16:37,911I'm not gonna name any names
    00:16:39,019but I'm just telling you you can do it.
    00:16:41,585So for this tutorial I'm gonna show you
    00:16:44,706the cross blur because it's kinda interesting.
    00:16:47,544What the cross blur does is it let's you blur,
    00:16:51,032it blurs an image on X
    00:16:53,848and Y separately
    00:16:55,286and then blends those two together.
    00:16:57,315It's sorta like using a directional blur
    00:17:00,088horizontally and vertically and then combining
    00:17:02,333those two layers together.
    00:17:04,352It just does it in one effect
    00:17:06,117and you can add the two blurs together
    00:17:09,245and you can get some interesting effects doing it.
    00:17:12,083So I'm gonna use this blur and you can see
    00:17:15,361you get this kinda cool hard edge to it
    00:17:17,670when you do this.
    00:17:19,066And you can really crank this up
    00:17:20,623and get some interesting looking blurs, alright?
    00:17:28,087And now this blue it feels a lot brighter
    00:17:30,229than the green so I feel like I need to make
    00:17:32,143the green a little bit brighter and probably,
    00:17:39,112probably need to
    00:17:41,540just kinda equalize the glow levels
    00:17:43,577across all three of these.
    00:17:45,211So anyway you can see that using the glow,
    00:17:49,488doing a glow this way is incredibly flexible.
    00:17:53,441And if you
    00:17:55,759see something on Motionographer
    00:17:59,078or you see a commercial and you see a glow
    00:18:01,930that has a unique look, it's de-saturated,
    00:18:04,934or it's a different color or it looks like this
    00:18:08,050where it looks like it was blurred a certain way,
    00:18:10,290you can create all that and then just add them
    00:18:14,479to your base layer, and now you have
    00:18:16,127a glow that you can totally control.
    00:18:19,117So this is the way I suggest doing glows.
    00:18:22,166And I'm gonna show you one more
    00:18:23,504thing before we end the tutorial,
    00:18:25,176so let me just show you real fast.
    00:18:27,486If I solo the original layer,
    00:18:29,305this is where we started, this is where we
    00:18:31,262ended up with our three glow layers.
    00:18:34,113Now this is sort of the tedious way of doing it
    00:18:37,820and even though you can do it very quickly
    00:18:40,384sometimes you have a dozen layers
    00:18:42,954that all need the same glow,
    00:18:45,656and you don't have time to make masks
    00:18:48,284and do all these things.
    00:18:49,478So I'm gonna show you a great way of doing that.
    00:18:54,277So let's just say we wanted, I just turned
    00:18:57,563all these glow layers off.
    00:18:58,785Let's just say that we had our original layer
    00:19:01,039and we wanted to make a good glow
    00:19:03,513that we could then copy and paste and apply to other layers.
    00:19:07,434So what we're gonna do is pretend
    00:19:09,687that we have duplicated this layer,
    00:19:11,469even though we haven't,
    00:19:13,214and we're going to add the Levels effect.
    00:19:17,489I'll crush the blacks,
    00:19:21,394til we have just these parts of the image.
    00:19:25,874We're gonna add the Fast Blur.
    00:19:30,576Okay?
    00:19:31,745And now we need to un-crush the blacks
    00:19:33,269a little bit just like before.
    00:19:36,524Now at this point we also need to make sure
    00:19:40,514we have this set, Clip To Output Black, needs to be on.
    00:19:43,568Now at this point if we had a copy
    00:19:47,135of this layer
    00:19:49,536and that was what we were working on
    00:19:50,999we would just set that to Add mode.
    00:19:53,220The problem is if you have a dozen layers
    00:19:55,667that need this glow you don't want to have to have
    00:19:57,481a copy of every layer making 24 layers now.
    00:20:02,164That's one of the things about After Effects
    00:20:04,221that I don't like is that a lot of things
    00:20:06,484require you to duplicate layers
    00:20:08,223that you really don't need to duplicate
    00:20:09,948in a node based compositor.
    00:20:12,489Luckily After Effects has this cool effect
    00:20:15,633that a lot of people don't know about
    00:20:17,927but it's incredibly useful and I'm gonna show it to you.
    00:20:21,210If you go to Effect, Channel, CC Composite.
    00:20:27,057Now when you apply this by default
    00:20:30,303all it does is take the original image
    00:20:33,660before any of these effects, before the levels,
    00:20:36,250and before the fast blur have been applied,
    00:20:39,268and it puts it back over itself.
    00:20:41,587So you're basically back to zero,
    00:20:45,726which is not what we want.
    00:20:47,454All you need to change is this Composite Original.
    00:20:50,314So what this effect does is it takes your layer,
    00:20:55,217applies Levels, then Fast Blur to it,
    00:20:58,655then it, this CC Composite effect
    00:21:00,791takes the original unaffected layer and composites it
    00:21:04,285with itself after you've put the effects on.
    00:21:08,630I don't know if that made any sense
    00:21:10,611but if I, essentially if I change this
    00:21:13,306from In Front to Add, we are now
    00:21:17,200basically adding the results of Levels and Fast Blur
    00:21:20,309to the original image.
    00:21:21,905So we're doing what we did before
    00:21:24,809using two layers with one layer, alright?
    00:21:28,344And if you turn this effect off this is now your glow
    00:21:33,759that is being added to your original layer.
    00:21:36,696So what's great is that now we say,
    00:21:38,976"Okay, look at this, this glow looks pretty good.
    00:21:41,391"Maybe we wanna boost the whites a little bit
    00:21:43,357"so it's a little more intense,
    00:21:45,544"but then we wanna bring the white level down."
    00:21:48,690However it's very saturated,
    00:21:51,279I wanna de-saturate that glow a little bit.
    00:21:54,073So what's cool about the CC Composite effect
    00:21:57,068is that you can think of it almost like
    00:21:59,793it's splitting your layer in half.
    00:22:02,108If we now add a Hue Saturation effect to this layer
    00:22:06,922if I bring the saturation all the way down,
    00:22:10,747you can see it makes our entire layer black and white.
    00:22:13,464That's not what we want.
    00:22:15,020If this effect comes after the CC Composite
    00:22:18,479it will affect the entire layer.
    00:22:20,981If it comes before the CC Composite,
    00:22:23,688so we just drag it above this effect,
    00:22:27,204now it's only affecting the image,
    00:22:31,756the effected image before this effect.
    00:22:35,137So if we turn this effect off again
    00:22:38,160you can see that this is now the result
    00:22:42,419that is being added, 'cause we're in Add Mode,
    00:22:46,679to the original, alright?
    00:22:49,977So this is great because if you had five other layers
    00:22:53,625now that you wanted this glow with you could
    00:22:57,143just copy this effect stack here
    00:23:00,779and paste it and have that exact look on each layer.
    00:23:06,388This is useful for a lot of other things
    00:23:08,069but for glows it's incredibly useful
    00:23:10,983because you can stack a whole bunch of effects
    00:23:14,247and you don't have to use a Fast Blur
    00:23:15,917you could use the Cross Blur if you wanted.
    00:23:19,026But as long as you end your chain
    00:23:20,875with CC Composite set to Add,
    00:23:22,650and it doesn't have to be Add it could also be Screen
    00:23:24,664if you wanted a little bit less intense of a glow.
    00:23:28,529But as long as it ends with the CC Composite effect
    00:23:31,376you get your glow and it's all in one layer
    00:23:34,509and you don't have to mess with all those other layers
    00:23:36,757and masking and all that stuff.
    00:23:39,210So anyway I hope this was really useful,
    00:23:42,203there's a lot you can do with this.
    00:23:44,947It really takes a lot of playing around
    00:23:47,151with different effects to find what effects
    00:23:50,206you can combine to make cool glows.
    00:23:53,617Another thing I like to do is to add noise to glows
    00:23:57,361so that it kinda breaks them up,
    00:23:58,753and you can do that using this method.
    00:24:01,792And that's all, so until next time
