Editing Shots — Positioning / Motion

Positioning Objects

Many objects in a shot can be positioned. In the example here, we'll position a Title.

With the Title element selected, click on "Position" tab in the Shot Editor. It should look like this:

As you can see, the Title element is positioned in the bottom middle of the screen.

To move objects, you use the mouse in the preview area at the top of the window.

Here are the options you have while holding the mouse down:

  • Move -- Move the mouse in the preview area

  • Resize respect aspect ratio -- Hold Command key down while moving the mouse vertically

  • Resize -- Hold Command key and shift key down while moving the mouse vertically (Respect Aspect Ratio must be off)

  • Rotate -- Hold down Option key)

If you've resized or cropped the object, the Arrow widgets can help reposition the Title around the window:

In addition you can use the mouse in the Preview area on the top of the window.

With this jump-start, the other options are relatively straightforward. Some of them may not be useful for a Title, but will as you work with other objects. Think of Backgrounds for tiling...

Motion for Objects

All Objects (Such as the Title object) can have motion assigned to them.

Click on the "Motion" Tab, your window should look like this:

Motion will only occur during a transition. (when you have pressed "Go", or if AutoLive is on and you change a shot).

It occurs when the object (a title in our case) needs to be added or removed from Live. It defines how that adding (Build-In) or removing (Build-Out) will occur.

There are two forms of Motion:

  1. Build In

    Build In motion occurs when the object (Title, in our case) is taken Live when it does not already exist in Live.

  2. Build Out

    Build Out motion occurs when the object (Title, in our case) was Live and at the end of the Transition will no longer be Live

You've been using build-in and build-out already - when you clicked between shots when you first opened Wirecas the default behavior was occurring - Fade-In and Fade-Out.

Changing Motion Options

Let's Change that behavior, Change the Build-In parameters by selecting "Left" from the popup and checking "Decelerate In"

To see this behavior in action, you must go back to the main window and trigger the Build-In.

Here's how to trigger it:

  1. In the Main window, make sure "Smooth" is the Transition.

  2. Click on the Blank Shot.

  3. Click on the shot you've been editing.

    Notice that when the Title appears it now has motion.
