If you click the dark green area, you drag the active video segment through the timeline rather than moving the video content through the active segment, as indicated in Figure 25.41...

Lifting the work area deletes the video layer inside the work area, but leaves a gap where the video

used to be

Performing Slip Edits

Performing a slip edit is simply a matter of dragging video footage through a trim, gap, or extrac-tion in that video footage For example, I have created a gap in my footage by lifting the work area

Now I want to add another video file to fill the gap I add the file and trim the ends to fill the gap perfectly, as shown in Figure 25.39

After I trimmed the new video clip, I realized that I wanted a slightly different section of video

Without the capability of a slip edit, changing this clip would be a multistep process: I would have

to drag the ends of my video to the portion of the clip I wanted and then drag that section back into place to fill the gap A slip edit can do all this in just one easy step

FIGURE 25.38

Extracting the work area deletes the video layer inside the work area and closes the gap

To perform a slip edit, simply grab the light green area at either side of the video clip and push it into the visible content The content stays in the same place, but the video contained inside the content changes It’s lots of fun to watch and difficult to show you with the still images in a book, but you can see in Figure 25.40 that the content has changed in relation to the current time indicator

When you are trying to slip edit, be sure you click the light green area to drag your video content

If you click the dark green area, you drag the active video segment through the timeline rather than moving the video content through the active segment, as indicated in Figure 25.41

FIGURE 25.39

After trimming this video clip, I realized that I want the clip to start later, so I perform a slip edit

Adding Still Shots or Other Elements to a Video Project

Adding still images or other elements, such as text layers or a 3D model, is very similar to adding video files These kinds of files look different from a video file in the timeline as well as the Layers panel, however, so I show you some of the things that distinguish these files

You can add still image layers to your video project in several ways When I say still image, I’m lumping together all the different kinds of images that can be manipulated in Photoshop—photos, paint, vector images, and text So it makes sense that you can add them in so many ways, from cre-ating a new layer to placing a separate file

FIGURE 25.40

Use the light green area in the layer duration bar to push the content through the active video segment

Adding a blank layer

If you are building an image rather than importing it, you want to create a new layer for the image, especially if your other layers consist of video files To add a blank layer, simply click the New Layer icon at the bottom of the Layers panel You also can choose Layer ➪ New ➪ Layer or press the keyboard combo Shift+Ctrl+N A new layer is created in both the Layers panel and the time-line, as shown in Figure 25.42 Change the name of your layer immediately You can move your layer up and down in the layer hierarchy by dragging and placing it in the right spot in the Layers panel An empty layer is a blank canvas waiting for you to create whatever you want

Adding a text layer

Adding a text layer is as simple as choosing the Text tool from the Toolbox, clicking your docu-ment, and typing text A separate text layer is automatically created, which allows you to move and edit the text separately from the rest of the file

Clicking the dark green, or active, segment of the layer moves the segment through the timeline.

Creating a title for a video project is the perfect example of optimizing the Photoshop tools to cre-ate the best results for your video project You can crecre-ate a title for a video file in Photoshop, or you can create a title separately to import into a video project being created in a different applica-tion Either way, the tools in Photoshop make it easy to create a custom, classy title

Adding or placing an image file

If you have a photo or an image that is a separate file, you need to add it to your video file for it to

be part of your project This is easily done by choosing File ➪ Place and browsing to the file you want to add The file is added to the video file in a bounding box that you can scale and rotate to place the file just how you want it inside your video project

You also can drag a new file in by clicking the layer containing the still image and dragging it into the window of your video file You also can copy and paste all or part of an image file

Adding a new layer is as easy as clicking the New Layer icon in the Layers panel.

Placing or dragging an image into your video file creates a new layer in your video containing the new image file If you copy and paste an image, be sure to create a blank layer to paste it into

However you bring an image in, make sure the layer is labeled well and placed in the hierarchy where it needs to be

Note

When you add blank layers, text, images, or 3D objects to your video, they are placed so the layers are active

throughout the duration of the video If you are creating a title or placing a short image clip, you want it to be

shorter This gives you the perfect opportunity to practice your newfound video editing skills n

Adding or placing a 3D model

You can add or place a 3D model in the same way you add a still image: Simply choose File ➪ Place, or drag the object into your file

You also can choose 3D ➪ New Layer From 3D File This option adds the object as if it has been dragged in, not giving you a bounding box to change your placement options

If you drag a 3D object from its own file or create a new layer from a 3D file, the 3D object is brought

in as a 3D layer You can transform the 3D object directly from the file it has been placed in

becomes a Smart Object You can still edit it and transform it, but you have to open the originating file to do so This creates an extra few steps in the editing process

A 3D object is distinguished in the Layers panel by the 3D icon in the corner of the layer thumb-nail A Smart Object has a different icon, as you can see in Figure 25.43

FIGURE 25.43

Placing a 3D object creates a Smart Object; dragging it in leaves it as a 3D object
