Reading scopes in a NLE

- Now, we've been looking at making adjustments inside of Photoshop, reading the overall histogram, but when working with video, there are some very useful tools, the waveform monitor and the vectorscope. Now let's jump into Premiere Pro and take a Photoshop file in there and I'll show how we can spot some issues as well make tweaks to overall fix things. What you're going to want to do is make sure that you get things balanced correctly. So I'm going to leave this here, and things look pretty good where I've got maximum flexibility. Let's go ahead and save that, and I'll put that to the desktop, and bring that into Premiere Pro, and I'll right-click and make a new sequence from that. You'll notice in this case that on the histogram some of the data is getting pretty bright. You also see how the white point isn't pure. We have a little bit more intensity of the reds than the greens than the blues. So this is actually indicating a slight color cast. Now, some people will choose to go back to Photoshop to fix it, but I can actually fix it here as well. Let's just apply that Lumetri Color effect, and I'll going to pull the effect controls over here for a moment, and let's take a look here under the color wheels. So in the highlights here, there's too much red. So if I pull away from red towards green and blue, notice how the red shifts down or we could take a look here at some of the other sections such as curves, and make a slight tweak. I can go to the blue curve for example, and add a small control point there and pull up on the highlights. Now, what's important is that the rest of this curve doesn't move too much, so let's add a few points there, and just lift up, and notice how the blue value raises, getting rid of some of that color cast. What I've introduced to you here is some pretty complex techniques. Don't worry about mastering it right now, but what you're seeing is that looking at tools like a vectorscope, like a waveform monitor, like a histogram, are useful because they will show you when things like exposure is over or underexposed, or when you look at channel view, you can actually see when the color is out of balance, when the white point isn't exactly white and the shadows or the highlights have a slight hue or a tint. This can be quite useful as you learn advanced tasks like color correction and color grading.
