# Animation settings dialog

The animation settings dialog is opened by the button from the animation toolbar. It provides settings for frame rate and playback speed of the animation. You use this dialog to change the length of your animation.

## Settings

Frames per second

  Sets the frame rate of your animation in Frames per Second. This affects the playback speed of movie files generated by OVITO.

Animation start / end

  Sets the active time segment displayed in the time slider. This controls the length of the animation, i.e. the number of frames.

Playback speed in viewports

  Controls the playback speed of the animation in OVITO. This factor is multiplied with the frames per second parameter. Note that the effective playback speed may be lower if loading, computing, and displaying every frame take too much time.
