Join Nick Harauz for an in-depth discussion in this video Applying Light Leaks, part of Sapphire for Video Editors.
- Let's take a look at S light leaks. Here in my effects tab, just located up here on the top, right-hand corner, cause' I am in my effects workspace, I'm going to do a search for S, underscore lights, get a few lighting effects and if i actually select my clip here, in the timeline and then double-click the effect, you can see the light leak is applied and it creates this lovely popular, light leak effect across your clip. With my clip select, I'm going to press Shift 5 to go into effect controls and I want to draw your attention, of course, to just maybe, to a little bit of searching here with presets.
If you load a preset specifically with light leaks, I would recommend rather than preview on source at first, just to preview on black, cause' you'll get a sense of what is actually on top of your clip. So, you can see here, this is the default. Colors that are play, they're pretty fast moving. If I start to use my arrow keys here, the right arrow, I'm able to just cycle between all of the various types of light leaks that are available to me. Let's just say that we want or find, like we had before, a starting place for something that we like and that happens to be for me, in this case, the pastel flicker.
I'm just going to press load to load it on the clip and then we can see the light leak at work here on my image. First off, you've got this scale light setting and if I scale up the lights here, it actually scales up all the lights in the image. So you can see every single light is scaled up that once. I press control Z to undo and in this particular case, let me use my play ahead and scroll to a part where I can see the light leak. I'm going to just play with this value and bring it up just ever so slightly, maybe to 1.3.
There's an overall color to these light leaks, however, there are different colors at play but just to show you, if you change the color here, you might change the overall look, in some cases of the light leak. So I've just introduced more of a reddish color and you can take that color and you can actually just now play and offset the hue. So you could actually make another main color all together and play with the saturation and the gamma off those light leaks. Usually, I find that the presets are set up to be very fast and I prefer, that in the cases of the majority of videos, I do, for the light leaks to be a bit slower.
The advantage of seeing them very fast, is that you get a sense of what you can do with them but I prefer to really bring down the speed and I'm going to just make this a very subtle value of about .3 and if I just move my play ahead, kind of halfway between the clip, you can see that those light leaks are definitely not moving as fast across the image. Other things we can control is how much they flicker. Right now, there's a flicker frequency of four. If I want them to flicker more, I can set a value of 12 and we're going to see just a much more flashy type light leak occur across our image.
In fact, it's almost flickering about 12 times a second. Didn't want that so much, so I'm just going to undo the value by pressing control Z or command Z and let's just go down a little bit more. Your light leak is actually made of various elements and right now, one element is selected. The reason that we see varying color, is because element one actually consists of three colors. I mean, there's the main color but these are the three colors that make up the one pastel flicker across your image.
So if you started to play with these parameters here, you could actually add to the overall main color, to bring the point home, that you've got a lot of flexibility and a lot of options here for when you're playing with your light leaks. I've got color controls over this individual element and also have the ability to add yet another element to the scene. So if I enable this second element, we might see an additional light leak at the scene. The first thing I'm going to do is actually play around with the brightness.
Now we can see, the second element and its colors. So I'm going to come down here to each of its colors and start to play with that and I'm also, you can play with the size, if you wanted to like, cover the overall image or just a particular section of the image itself. In my case, I do want to keep it at the value of one. Having it quite big but maybe bring down that brightness overall. So it's a bit more subtle across the image.
I'm a big fan of each of the individual light leaks moving slowly. So I'm going to play here with the speed tube, the second element that I added and make it a value of point two. In other things, such as softness, could add to the overall movement that you have here. If I come back here to the overall value of point one, I'm slowing down all of the elements that make up my light leak. There is a bit of control that's happening there, if I got and scroll down and start to play with the value of such as flicker that we saw earlier and make that a value of one, we see that every single value below it, has become affected and keep in mind, if you find something you like, you can always save a preset to the Sapphire Library and then have it available for your next project.
