Lesson 12. Subclips and Virtual Clips > Assembling the final video program

Assembling the final video program

You'll now nest the virtual clip you just made inside a new virtual clip. In this new virtual clip, you'll combine the Masked Background virtual clip along with another video clip and some still images, adding another Image Mask transition. This time, we'll use this transition to make a clip and a collection of still images play on top of our background effects through our image mask. First, you'll add a new scene to the project.

1.
In the Navigator, use the slider or zoom buttons to set the Timeline unit menu to 1 Second so that you can see more detail.

2.
Scroll the Timeline or drag in the Navigator palette so that just Masked Background is displayed.

3.
Drag Surf3.mov from the Project window into the Video 1A track so that it snaps to the beginning of Masked Background.

The still images you'll be adding to this project will be inserted in the middle of Surf3.mov. To make this insertion possible, you'll use the razor tool to cut the clip in two pieces.

4.
In the Timeline window, select the razor tool (), and click about in the middle of Surf3.mov.



Surf3.mov is split in two pieces.

5.
Select the selection tool () to deselect the razor tool.

Before you add the still images to the project, you'll make a change to the preferences that will set the duration of the stills automatically as they are imported. Note that you must make preference change before you import the still images.

6.
Choose File > Preferences > General/Still Image. Under Still Image, type 5 for the Default Duration for Frames, then click OK.

7.
Choose File > Import > Folder, select the Images folder in the 12Lesson folder, and click OK (Windows) or Select 'Images' (Mac OS).

You'll add all 10 still images at once between the two portions of Surf3.mov you created with the razor tool.

8.
In the Project window, double-click the Images bin to open it and choose Edit>SelectAll to select all 10 files in the bin. Drag these files together into the Video 1A track, between the two segments of Surf3.mov. Close the Images bin.



The virtual clip is slightly longer than the clips you've assembled in the Video 1A track. Because you want the material in both the Video 1A and the Video 1B tracks to be the same length, you'll trim the virtual clip, just as you would trim any other clip.

9.
With the selection tool () selected, position the pointer on the right end of Masked Background and drag left until it snaps to the end of the last Surf3.mov segment above it.

Next you'll add the Image Mask transition with a new mask shape.

10.
From the Transitions palette, drag the Image Mask transition into the Transition track, so it snaps to the beginning of Masked Background.

11.
In the Image Mask Settings dialog box, click Select Image, and double-click Mask2.tif in the 12Lesson folder. Then click OK to close the Image Mask Settings dialog box.

12.
Resize the transition by moving the pointer to the right end of the transition and dragging right until it snaps to the end of Masked Background and the other clips you just assembled.



13.
Preview the two clips and the transition you just assembled by scrubbing through the Timeline ruler while pressing the Alt key (Windows) or Option key (Mac OS).



With the transition in place, you'll apply the Invert filter to Masked Background and set the keyframe markers so that it affects this clip only when the still images are playing. To make this easier, you'll add two unnumbered markers to aid in setting where the filter starts and ends.

14.
In the Program view, drag the shuttle slider to position the edit line near the beginning of Masked Background in the Timeline. Click the next edit button () to move the edit line to the beginning of the Still01.tif, and choose Clip > Set Marker > Unnumbered.



15.
In the Program view, drag the shuttle slider to position the edit line in the last segment of Surf3.mov in the Timeline. Click the previous edit button () to move the edit line to the first frame of the last segment of Surf3.mov. Now click the previous frame button () under the Program view to move the edit line to the last frame of Still10.tif and choose Clip > Set Marker > Unnumbered. Move the edit line away from the marker so it won't interfere when you align the keyframe to the marker.



Now you'll apply the Invert filter to Masked Background. This filter inverts each color to its complementary color.

16.
Select Masked Background and open the Filters dialog box.

17.
Select Invert in the Available list and click Add. Drag the dialog box so you can see the markers in the Timeline and the Program view.

18.
Drag the first marker on the Keyframe timeline right until it is aligned with the unnumbered marker at the beginning of Still1.tif.

19.
In the same way, drag the end marker on the Keyframe timeline left until it is aligned with the marker at the end of Still10.tif. Click OK to close the Filters dialog box.



20.
Preview the clips you have assembled by scrubbing through the Timeline ruler while pressing the Alt key (Windows) or Option key (Mac OS).



21.
Save the project.
