Video: Pulling a luma key

Now I'm not quite sure why, but I've always found this shot mildly amusing. Just a bunch of camels walking in the desert, but I looked at it and I thought it'd be really kind of cool if we could have their silhouettes over top of a graphic. So I've created a graphic underneath this video layer and this also happens to be a perfect shot to pull a Luma Key. So let's stop playback for a second, so I can explain what a Luma Key is. If you go to the Library tab, under the Filters section, under Keying, when we select Luma Key, in Motion it's defined by saying Pulls a key based on luminance.

Motion 4 Essential Training
6h 21m Beginner Sep 11, 2009

Viewers: in countries Watching now:

In Motion 4 Essential Training, Ian Robinson shows how to start building outstanding motion graphics and animations for video production. He demonstrates how to build custom text animations with the new Adjust Glyph tool and explores Motion’s amazing real-time 3D tools. Ian highlights working in the 3D space, creating depth with lights and shadows, and using reflections to add realism. He gives practical advice on how to integrate Motion into a professional video workflow, round-tripping with Final Cut Pro and sending a final project to Compressor. Exercise files accompany this course.

Topics include:
  • Understanding the toolbar and setting the essential preferences to get started
  • Adding .mov files, still images, and Photoshop and Illustrator assets to a project
  • Animating with behaviors and keyframes
  • Creating 3D animations with lighting accents, shadows, and reflections
  • Creating simple and complex particle systems
  • Creating real viewer interest with Focus Behavior and the 3D Camera Framing behavior

Pulling a luma key

Now I'm not quite sure why, but I've always found this shot mildly amusing. Just a bunch of camels walking in the desert, but I looked at it and I thought it'd be really kind of cool if we could have their silhouettes over top of a graphic. So I've created a graphic underneath this video layer and this also happens to be a perfect shot to pull a Luma Key. So let's stop playback for a second, so I can explain what a Luma Key is. If you go to the Library tab, under the Filters section, under Keying, when we select Luma Key, in Motion it's defined by saying Pulls a key based on luminance.

Well, if you don't know what luminance is, that's not a big help. But basically, if you remember from our definitions section, luminance is the brightness of the image and we'll use a Luma Key to key out the brightest parts of this image, which just happened to be the sky and we'll keep the darker parts of the image, the camels and parts of the ground. So let's get started. To apply the Luma Key, just drag it and drop it right on to the canvas. You'll notice the graphic is already starting to appear.

But to make adjustments, let's go to the Inspector under the Filters tab and let's adjust our Luma Key. So the key mode, by default, is Key Out Brighter. Since that's what I wanted to do, that will work beautifully. Under Luminance, we'll leave it for NTSC because that's what this footage is. Let's adjust the Threshold a little bit to darken up this shot. We can also adjust the Tolerance if we bring that down. You can see we can get a little bit more tolerance in the image. Now I can tell this isn't really going to work, so let's turn off the Luma Key for right now and let's intensify the contrast of this image.

If you go up to Add Filter > Color Correction and choose Contrast, now we'll crank this up and let's drag the Luma Key on top of the Contrast to make sure we have the proper filter order. Now let's turn the Luma Key back on and see what we've got. It's getting a little bit closer. Let's adjust the pivot point. There we go. Let's press Play and check out our graphic. It's getting there, but this is still a little bit noisy.

Let's adjust the Contrast a little bit more. Make sure to click directly in the number value slider, so you can drag to a higher value than this actual slider to the left. Now let's go ahead and press Play and, I think, this is a little bit more along the lines, just to what I was looking for. Now as you can see if you just think a little bit outside the box, you can create some pretty interesting graphics, all using the Luma Key.

Q: In Motion 4, is it possible to create an intro with multiple pictures, where some pictures enter from the left side and some from the right side of the frame, with all fading as they approach the center of the canvas?
A: The effect described is a very specific move utilizing 3D space.  One effective method is to work in true 3D space, instead of trying to use a behavior, by keyframing the animation. Try these steps:
  1. Place a camera in the scene and switch the scene to 3D. 
  2. Rotate the first image to an angle that achieves the desired effect, and slide it on the X axis until it is out of the scene on the right of the stage. 
  3. Turn on Auto Keyframing and make sure a keyframe is recorded for the rotation and position. 
  4. Move the playhead down the Timeline and move the picture to it's ending point and adjust the rotation a little for the end. 
  5. To get the image to disappear, adjust the camera's far plane of view, making sure to soften it so it has a smooth transition into oblivion. 
    Then simply duplicate the picture and change the rotation and position keyframes to the exact opposite values for rotation and position. 
Q: When attempting to change views as the instructor demonstrates in the “Viewing a 3D scene in different layouts” video, I only see the text in the Perspective view. When the instructor uses the Top and Bottom screen split, and uses the Top view, my screen does not show the four horizontal lines that represent the four words used in the tutorial.
Are there settings that need to be changes in order to view all the objects as demonstrated in the tutorial?
A: It’s possible that when viewing the project from different?angles, the letters may be sliding way out of the view area.
Here’s how to fix it: Whenever you can't see your objects in the?scene, select at least one of them in the Layers panel and then press?F or Command+F to frame the selected objects in the scene.
