Changing the play speed

To change the speed at which your take plays in MotionBuilder:

Select a play speed in the Play speed field in the Transport Controls window.
By slowing down the play speed, you can analyze model and camera movements more easily.

NoteTo compensate for computer speed, frames may be dropped for playing in real time in all play speeds, excluding the ALL FR option.

You can also speed up play or draw every frame. You can also scrub through the animation by jogging.

Jogging Animation

Jogging is the easiest way to scrub, or move backward and forward, along the timeline at the play speed you want.

Note If you jog animation, it affects any audio on the timeline if the Enable Scrubbing option is active in the Audio settings.

To jog through the current take:

J-drag in the Viewer window, or on a timeline.
Drag left to jog backward, or right to jog forward.

The further you move the mouse pointer relative to the location in which you J-click, the faster the take plays.

Selecting a frame rate

You can change the frame rate at which the take plays. You can select frames-per-second (fps), NTSC, or PAL formats from the menu, or use the Custom option to enter a custom frame rate. The default time format is 24 fps.

NoteFor information on changing the time display, see Selecting a time format.

To select one of the main frame rates:

In the Transport Controls, select one of the options in the Time Format field.
