In this exercise, you'll learn the basic operation of the Timeline and how clips are laid out in the Timeline, and discover the similarities between how the Viewer and Timeline play back clips.The Timeline and the Canvas are, essentially, two views of the same thing. The Timeline allows you to organize your clips from start to finish, whereas the Canvas displays the video under the Timeline playhead. You need both to be able to edit and view your program.
1. Start by opening Chapter 02 Lesson, if it isn't already open.If you already have it open, chooseFile > Revert(and clickOKto agree to lose all changes)to reopen the project to the condition it was in the last time it was saved.[View full size image]Notice that when you open this project, a sequence automatically opens into the Timeline. The Timelineis the window that contains sequences of edited clips. You can have as many sequences open as you likein all cases,though, they are displayed in the Timeline.
NOTE | Sequences Take Memory
Although Final Cut allows you to open as many sequences into the Timeline as you want, the more sequences you open, the more memory they will take. For this reason, I make it a habit to keep the number of open sequences to a minimum. Sequences in the Browser take almost no memory, but memory is allocated when they are opened in the Timeline.The Timeline is divided into four main sections: video tracks and audio tracks that contain clips, track controls, and Timeline controls.[View full size image]The audio and video clips section of the Timeline is divided into two halves, separated by the double-gray line in the center: the top half contains video clips, displayed in blue, and the bottom half displays audio clips, displayed in green.Each horizontal line of clips is called atrack. Final Cut allows you to create sequences containing up to 99 tracks of video and 99 tracks of audio. In general, you stack clips vertically when you want more than one image (or sound) on the screen at one time. You lay clips out horizontally when you want one shot followed by another. The shot on the left goes first.
NOTE | Turn Audio Waveforms Off for Better Performance
Although the Timeline in this exercise shows audio waveforms on, you'll get better performance from Final Cut Pro by turning waveforms off because when they are on, the computer needs to allocate CPU resources to calculate them. Especially if you are using a slower computer, turning waveforms off will make a big difference in how quickly Final Cut responds.Chapter 4," Build Your Story."On the left side of the Timeline are the track controls. The green visibility indicators are all lit by default. Turning off the visibility indicator for a track makes a video track invisible or an audio track inaudible. You'll work with these more in Chapter 7," AudioThe Secret to a Great Picture," and Chapter 10," Motion Effects."
7.
Put your playhead in the middle of a clip. Click the green visibility indicator next to the V1 patch panel. Notice that your Canvas has gone black because all your video clips on the V1 track are now invisible.
8.
Turn off the green visibility indicators for all audio tracks and play a portion of your sequence. Notice that now all the audio has become silent.
9.
Turn on all visibility indicators by clicking them so they glow green.The patch panel controls how audio is routed from the Viewer to the Timeline. You will learn more about this in Chapter 7," AudioThe Secret to a Great Picture."The track locks are off by default. Turning a lock on makes it impossible to make changes to a track, including repositioning a clip. You'll learn more about them in Chapter 6," Trim Your Story."Chapter 5," Organize Your Story."
10.
At the bottom left of the Timeline are the Timeline controls. Click one of the four bars in the "bar chart" and notice how the height of the tracks changes.
11.
Click the small right-pointing triangle to display the pop-up menu for the Timeline. You've already used this to turn off, or on, the display of audio waveforms. Turn on, or off, the other four options in the top section of the menu and watch what happens.
12.
Click one of the bottom four choices (Reduced, Small, Medium, and Large). Notice that choosing one of these is exactly the same as clicking the blue/gray bar chart icons immediately to the left of this menu.
13.
Next, grab the horizontal track Zoom slider and slide it back and forth. Notice how it repositions the Timeline.
14.
Now, grab either end of the Zoom slider (I tend to call this the "mad popsicle stick") and change the size of the slider bar. Notice, as you do so, how the horizontal scale of the Timeline changes.
15.
If you want to stop, choose File > Close Project and don't save your changes. If you are ready to tackle the next stage, leave the project file open.
NOTE | Which Should You Use: Zoom Control or Zoom Slider?
By dragging the middle of the Zoom slider from left to right and back again, you can easily get from one side of a large sequence to another. It can also be used to quickly change the scale of the Timeline, by grabbing one of the tabs at either end and dragging. However, zooming using the Zoom slider changes the scale of the Timeline without any respect to the playhead.This means you can zoom in such a fashion that the playhead will totally disappear off the edge of the screen. When this happens, look in the Zoom slider track and you'll see a small, thin, almost invisible purple line. Click it and the Timeline will automatically jump to the current location of the playhead.Zooming by using the horizontal Zoom slider, however, automatically centers the playhead in the Timeline, then changes the scale. For me, using the Zoom slider, rather than the Zoom control, helps keep me from losing the playhead (which is the principal reason I call the Zoom control the "mad popsicle stick").Well, um, this is not totally true. I love keyboard shortcuts. So, if you want to know the truth, when I want to zoom in or out on the Timeline, I could press Cmd+ + (that's the Cmd key and the plus key) to zoom in, or Cmd+ (Cmd and the hyphen key) to zoom out.But, uh, if you demand absolute honesty, I don't really use any of these. I use the Zoom tool. I wasn't going to mention this until later, but, well, you force me to reveal another secret.To access the Zoom tool, either click the magnifying glass in the Tool palette and select the Zoom tool with a plus (+) sign in it, or press the letter Z once. To zoom out, select the second Zoom tool, the one with a minus () sign in it, or press the letter Z twice. Then, drag the Zoom tool around the portion of the Timeline you want to enlarge (or shrink).Even faster, press the letter Z once, to select the Zoom In tool, then hold down the Option key to switch to the Zoom Out tool.Like I said, Final Cut has lots and lots of different ways to do the same thing.
