Using Adobe SpeedGrade CC, powerful professional color correction and color grading is available to anyone with a Creative Cloud membership. In this course, professional colorist Patrick Inhofer offers a project-based learning experience to get you familiar with the SpeedGrade tools. You'll work three different types of projects through the color correction and grading process, which includes getting projects and footage into SpeedGrade, color correcting and grading shots, and then rendering and outputting shots. Each step of the process is rich with lessons and anecdotes that are applicable to real-world color grading scenarios that editors, producers, and other creatives will face.
This course was created by Patrick Inhofer and produced by Robbie Carman. We are honored to host this content in our library.
In this movie, we're going to take a look at two things. The first thing we're going to do, is take a look at the analysis tools here in speedgrade, otherwise know as Waveform monitors, vectors, scopes, and histograms. The other thing we're going to do is take a look at those analysis tools which I find most useful when we're analyzing the contrast of a shot. Because the way I typically work is, I usually start with contrast, and then move on to color and saturation. If you have access to the exercise files, I'm working off of 02_05_analysiscontrast, and to find our analysis tools, our Waveforms and vector scopes, you've got this little disclosure triangle up here, and I can click that.
And it reveals my analysis tools. I can also use that to hide them, or use the shortcut key, the A button, and that'll toggle the analysis tools on and off. Now depending on if you've played with these or not, you may or may not be up here with the four scopes layout. To adjust that, we can adjust between one and four scopes. If I flip here to three scopes it changes around, and then I can right click in each of these scopes to select. Between one of the four scopes.
So instead of down here I wanted the RGB parade, I could right click, select parade, and now I've got my RGB parade down here. And if I want to move my Vectorscope up here, I can right click, select vector scope. There it is. There's also a thing to note here is this pull down menu for ten bit, eight bit, 16 bit, and float. That's going to change the, the numbering here on the right side of both the Waveform and the parade. So right now this is set for 10-bit, so it's showing me from 0 to 1023. I can also for instance flip this into float, and now 0% black is 0.0 and 100% white is 1.0.
And notice it changes for both of these displays. If I'm in a color shot, so I'm going to jump here to the last shot in the timeline, I have a choice on this LumaScope, I can right click and select switch to RGB which is usually its default state. And now it's showing me this RGB parade overlayed on top of each other. Or I can right click, switch to the Luma. And this is a Luma only or why only display. So, it's stripping away the color information and giving me basically the sum of what these three are, when they're summed together to the final image.
I find I use this on a fairly regular basis. Although I like to say, I make my living off the RGB parade scopes. So now the question is, what are the scopes or the analysis tools that I use on a regular basis when I'm looking at contrast? Well, number one is this y-only Waveform. I'm going to come down here and switch this to one scope, right-click and show Waveform. And, we're on the y-only and this is showing me. The image am looking at from black to white.
Now, I am going to go ahead and control left arrow, back to the first shot in this timeline and the first shot is this gradient with black on the left and white on the right and notice on this Wave form, I've got black on the left. Sloping up to white on the right. And every step in between, the Waveform is showing what each of these pixels are, reading from left to right. Now, if I go to the next shot here, I'm going to control right arrow, I flipped the shot and now we've got white on the left, black on the right, and notice we've got white on the left, black on the right.
In other words, the scope here reads the picture information and displays it from left to right. Now, I'm going to move to the next shot on this timeline. And also what I've got going on here, is I've got speed grade spelled out as text, but filled with a gradient. And you can see that absolutely, that the left edge of the S here is the left edge of the S here. And as we move across, you can see that there's a direct relationship between say this point in the image and this point in the Waveform.
Now, about the only time a Waveform will ever give you a (LAUGH) one-to-one relationship so you can read exactly what's going on here, is something like this, electronic text with a gradient in which every single pixel as you go from top to bottom is a different grayscale value. That's whats going on here, it's all a different grayscale value, but notice with something else, I'm going to move to the next shot where I've inverted the text itself. (LAUGH) I've inverted the text and notice that this is still reading the same.
Why is that? Because there is no top to bottom relationship in a Waveform monitor. When i flip this, I've got the white. The brightest part of this on the bottom, and the darkest on top. The Waveform doesn't care. The Waveform always displays the brightest at the top and the darkest at the bottom. So, essentially what you should walk away from this is the Waveform is a left to right display of the picture information. I come back to this last shot, what am I being shown here? Well, if I'm looking for her in this Waveform, I'm going to have to guess that she's in here and she's got some highlights up here and the sky has some highlights.
I'm thinking she's in this part of the image right here. And he's probably in this part of the image over here. Too little tough to tell. Let me hit play (NOISE) and I'm a take a look at where this camera is and she could be here, she could be here. It's a little tough to tell, but this is a left to right display. Now on the other scope I might use for this is the parade scope and it's essentially the exact same thing as the Waveform only showing me each color channel replicated. So if I come back to the very first shot in the timeline, I'm seeing each individual color channel.
And then I'll move to the next shot. And the next shot. And you can see I'm seeing SpeedGrade CC replicated out here. I move to the next shot. It doesn't flip over, remember? It's reading always from the brightest elements at the top, the darkest elements are always on the bottom. And it's replicating from red to green to blue. Now the thing is, when it comes to analyzing contrast this is useful, but the RGB parade for me is also a very valuable color balance tool. It will show me imbalances in color temperature very, very easily as I compare the red channel to the green channel to the blue channel and for more on that, we've to check out other video on doing on the analysis tools as to which tools I use when I am analysing color.
