6. Get on Top
Now that we have two clips in the Timeline, let’s work with multiple layers. Click on the second part and drag it straight down to place it on another layer. Then, drag it so that about a second of it overlaps the one above. Next, click on the first clip’s fade effect from step 2 to select it. Copy that effect (Edit > Copy or Command-C).
Step 6: By dragging our second clip down to a new layer, we can make them overlap to set the stage for a transition effect. Click to embiggen!

7. Cloning Away
Move the playhead so that it is at the start of the second clip (the playhead should snap to the edit point as you near it; if it doesn’t, go to View > Snapping). Select both clips by clicking on one and Shift-clicking on the other. Then, paste the copied effect (Edit > Paste or Command-V) to add it to both clips at the same time.
Step 7: We're pasting our fade effect onto the end of the first clip and the beginning of the second one. Click to embiggen!

8. Effect Alteration
With the playhead still in the same place, select the new top effect (make sure it’s the only selected item in the Timeline). Its Opacity slider should be at 100%. Select the bottom effect; set that Opacity to 0%. Move the playhead to the end of the top clip. Change the top effect’s Opacity to 0% and the bottom effect to 100%. You’ve just created a cross-dissolve.
Step 8: We're making a cool-looking cross-dissolve by fiddling with the Opacity slider. Click to embiggen!

9. Step into 3D
Move the playhead to the right of the cross-dissolve. Select the last clip and use the keyboard shortcut Command-K to create a new Video Action. Use the panel on the right to change the Scale to 40-50% and the Y rotation to -45 degrees. Play back the effect and watch your Desktop shrink and rotate clockwise.
Step 9: This Video Action rescales and rotates the Desktop image in your screencast. Click to embiggen!

10. Animate Anything
You can use actions to animate absolutely anything. For instance, move the cursor so that it’s a second or so after the rotation effect. Create a new Video Action. This time, tick the Reflection box and move the slider until it reaches 70%. Next, drag the new effect until it touches the previous one (actions cannot overlap each other). As you play the effect back, the reflection increases over time.
Step 10: Video Actions let you "animate" anything by changing it over time. Click to embiggen!

11. In and Out
Deleting specific segments, like an action or an entire clip, is easy: Click it to highlight it and press the Delete key. However, things can get a little bit more complex when you’re working with multiple layers. If the section you want to remove spans multiple clips, the easiest and quickest way to delete it is by using In and Out points. Move the playhead to the start of the section you want to remove and press the I key (or go to Edit > Mark In Point). Everything to the right of that point turns blue. You can then move the playhead to another location inside that blue zone and hit the O key (or use Edit > Mark Out Point).
Step 11: Set the In and Out points if you want to cut a portion of your screencast that exists on two layers. Click to embiggen!

12. Making Ripples as You Delete
Once the Out point has been set, dragging the blue zone’s edges alters the selected area’s dimensions, helping you be precise and only delete the section you want to get rid of. When ready, you must either use the Edit > Ripple Delete command or the Command-Delete keyboard shortcut to remove all the selected footage from the Timeline.
Step 12: Edit > Ripple Delete is the command you're looking for. Click to embiggen!
