Soundtrack Edit Controls

The soundtrack edit controls appear as follows:

The soundtrack edit controls are used to control the elements of the soundtrack which appears below in the soundtrack display area.

Playback Controls

Above the slider is a row of five buttons that control the major shuttle functions.

If you click one of the buttons, a black square appears around it.

If no region of the soundtrack is selected, the playback buttons play the portion of the soundtrack that is visible in the soundtrack display area. If a region is selected, the playback buttons play only that region.

These buttons appear as follows:

	plays the animation in reverse, but increases the normal speed by 25%.
	plays the animation in reverse. The speed is determined by the speed menu to the right of the playback buttons.
	stops the shuttle.
	plays the animation forward. The speed is determined by the speed menu to the right of the playback buttons.
	plays the animation forward, but increases the normal speed by 25%.

Fast PlayBack Mode

Many users need to utilize geometry to accurately see the effect of lip sync on their models, but on all but the most powerful machines this playback mode doesn't approach real time. To provide real time playback with geometry mode, a new playback mode has been provided that effectively "playblasts" the geometry frames.

To the right of the playback button, a new button that has the playback symbol and a small S has been added. In addition, the reference playback window has a pull-down men that selects one of Reference, Playback, and Off.

When the new Playback button is pressed, SoundSync plays forward, one frame at a time, on the current selected region. If no region is selected, it plays back the entire width of the window. It grabs frames from the Mixed keyset window and prepares them for playback in the Reference window.

Warning: This process can not be interrupted!

Once the frames are grabbed, the frames in the Reference window can be replayed in real time.

Example

A workflow might be as follows:

1. Select a region to work in. This region shouldn't exceed a few hundred frames (for memory reasons).
2. Position the viewpoint in the Mixed window to your liking. Turn the Keyset window Off.
3. Press the Play Forward & Save button, and wait while the images are grabbed.
4. Now select Playback in the reference pull-down menu and turn the Mixed window off.
5. Using the regular playback button (NOT the Playback & save), view the sequence.

Speed Menu

The Play and ReversePlay speed is selected from the speed menu to the right of the playback buttons.

The speed menu appears as follows:

There is no menu name as such; the selected speed appears on the top of the button as follows:

Loop/Once Menu

The Loop/Once menu is used to set whether the soundtrack plays through once and stops or whether the soundtrack plays through repeatedly from beginning to end.

The Loop/Once menu appears as follows:

There is no menu name as such; the choice selected, either Once or Loop appears on the top of the button as follows:

Add Key Button

The Add Key button appears as follows:

Clicking the Add Key button works in two different ways:

1. If a keyshape is selected from the active keyset, a keyframe for that keyshape is inserted at the current meter location.

   The smoothing type of the new keyframe is Ease.

2. If no keyshape is selected, no keyframe is added.

Clicking the Add Key button is the same as selecting Edit Add Keyframe or using the key sequence Ctrl-K.

Delete Key Button

The Delete Key button appears as follows:

Clicking the Delete Key button works in two different ways:

1. If a keyframe is active, SoundSync deletes it from the active keyset.
2. If no keyframe is selected, nothing is deleted.

Clicking the Delete Key button is the same as selecting Edit Delete Key or using the key sequence Ctrl-D.

Delete Key Region Button

The Delete Key Region button appears as follows:

Clicking the Delete Key Region button works in two different ways:

1. If a region is selected, SoundSync deletes all keyframes from the active keyset within the selected region.
2. If no region is selected, nothing is deleted.

Clicking the Delete Key Region button is the same as selecting Edit Delete Region or using the key sequence Ctrl-R.

Key Smoothing Buttons

The Key Smoothing buttons are used to change the transition between two keyframes. The buttons can be used when a single keyframe is selected or when a region of keyframes is selected.

The Key Smoothing buttons appear as follows:

The Key Smoothing buttons function as follows:

	makes the transition between two keyframes linear. A linear curve is displayed as a straight line in the same color as the linear button.
	makes the transition between two keyframes flat. A flat curve is displayed as a slightly curved line in the same color as the flat button.
	makes the transition between two keyframes smooth. A smooth curve is displayed as a curved line in the same color as the smooth button.

Zoom Buttons

The zoom buttons appear to the left of the slider bar as follows:

The left button zooms out of the soundtrack.

The right button zooms into the soundtrack, magnifying a small section over a larger area.

Clicking the buttons repeatedly zooms further in or out.

Zooming in to magnify a section of the soundtrack is very helpful when adding or deleting keyframes as it allows you to be more precise.

Slider Bar

The default slider bar appears as follows:

Scroll Bar

In its default state, the entire soundtrack appears in the soundtrack display area. Therefore, the scroll bar fills the slider bar area.

As you zoom into a portion of the soundtrack, the scroll bar becomes smaller and you can click-drag it to move to the portion of the soundtrack that you want to look at.

A slider bar appears as follows when the soundtrack is zoomed in to show only a very small portion of the soundtrack filling the soundtrack display area:

Scroll Arrows

The scroll arrows are buttons.

If you click the left scroll arrow, the soundtrack display moves in the same way that click-dragging the scroll bar to the left does.
