Join Nick Harauz for an in-depth discussion in this video Applying Glow, part of Sapphire for Video Editors.
- [Instructor] This chapter is all about Sapphire lighting. If you need to open up your chapter three_1 sequence, you can head into the Exercise folder that's located in your Project Panel. Press Shift + 1 to find it. You can just double click in the Exercise folder, or like I like to do, Control + double click, and find the chapter three folder, which will contain the exercise files for this movie. First thing that we want to look at is actually Sapphire Glow. And I'm here in my timeline, I'm just going to play back this clip so you can see it.
It's actually a lot of white in the scene, or high illuminance values. I'm going to head over here to my Effects tab, it's up here because I'm in my Effects workspace. And I'm just going to type in 's_glow', and just to show you it leads you to the Sapphire Lighting category, where there are a series of glows that you can use for your projects. I take 's_glow' and apply it to my clip, automatically you can see the high illuminance or white values, a glow has been applied. To take a closer look, we're just going to press Shift + 5.
I would like to encourage you, you can actually load a preset of over, I believe, 20 glows that are available in your library as a starting place. But since we're trying to get more familiar with how we can manipulate glow, I'm actually going to cancel out of here and start to work with the default glow. So there are two values that are really important. One is brightness, and that's how bright your glow is. What I would recommend that you do, when you drag on the brightness value, you can actually scroll it inside of Premier Pro. And if you hold down the Control key or the Command key on a Mac, this will do it in small increments and you can get a sense for how the brightness values can either overpower or work subtly across your image.
The value of two was a nice start. The other value that I encourage you to play with is Threshold. And Threshold exists between zero and one. Zero is like saying, "All the values in your image or all "the high illuminance values, "please be effected by this glow.". By putting a value of one, it's like, "Don't effect anything.". Holding down the Control key will allow you to scroll slowly, or the Command key on a Mac, so that you can play with the Threshold value to choose what you want to be effected by the glow.
Of course, we can change and manipulate the color. Sometimes I'll go into the Color Picker, and you can choose either a highly saturated color, or just something slightly off white. Let me just reset the parameter back to its white color. Of course, we can play with the width, which sort of plays with how far that glow extends. Rathr than just playing with the width, you can choose either the X or the Y axis. In this case, that glow is isolated to the Y width.
I'll just settle on a value of five in this case. Where things can get really fun in customizing your glow is to start to play with the individual red, green, and blue widths of your glow. But to really see this effect, I'm actually going to take this number and make it five green. So I'm just going to play with the width red as well, bring it actually very close to zero just to get a colored look. And then just start to play with these values until I end up with the glow look that I'm trying to achieve.
Really liking those colors so far, and just going to actually bring down the overall width of that glow. And we can sort of see that glow across the image limited to the Y axis. Let me just introduce a little bit of X so that we have it spread out a bit more. And now that I've made these adjustments, there's no harm in going back to the original brightness value that we changed, and if you bring it down to zero, you'll have no glow in your image. Of course, I can change that value to make the overall effect more subtle.
In my process of working with Sapphire, I'm making adjustments to some of the parameters, and then going back to some of the parameters at the top to control the overall look. So let me just scroll down and introduce you to one more thing that you might want to be familiar with here, especially with glow, is Atmosphere. And Atmosphere almost adds a little bit of fogginess or smoke to the glow. I'm going to start with like an amount of .2. And sometimes you might not be able to see this at first, so remember, if you control scroll your parameter, can get small increments, rather than the default faster way of scrolling.
So I'm going to settle on a value of just .3 so that we can see that, and even bring down the frequency a little bit more. And most importantly bring down the Atmosphere detail, because it just looks like it's too powerful. Something like .3. And then by scrubbing through the timeline, we can get a sense for how that Atmosphere is interacting with our overall glow. I'm just going to go back to the beginning of this project by pressing the Home button on my extended keyboard. And as you can see, there's the glow across the image.
All of these values for any lighting effect or pretty much any Sapphire effect, can be key framed. So if we want any glow here at the start, we can go back to our main parameter, such as brightness, and I'm just going to click the stopwatch to add a key frame. Make that value zero, and as we start to move up, I'll want it to reach extreme glow at two seconds, so I'll just make that brightness value about 2.5, close to where we were, actually a little bit stronger. We can see here that we start with no glow, and then slowly the glow is introduced across the image, adding even more to our clip.
So there you have it, an overview of working with 's_glow' inside of Premier Pro.
