Show Groups: Displays the Group layers in the Timeline.
Show Effects: Displays the Effect layers in the Timeline.
Show Sound: Displays the Sound layers in the Timeline.
Show Sound Waveforms: Displays the imported sounds waveform in the Timeline.
NOTEYou can always toggle the visibility of the waveform in the Timeline view by adding the Show Sound Waveform button from the Toolbar Manager. This button will work whether you have the Show Sound Waveform option enabled or disabled in the Preferences panel.
Show End of Scene Marker: Displays the red bracket that delineates the end of your scene in the Timeline view. If you know that many different hands will be working on your scene, you may want to deselect this option so the scene length is not increased or decreased by accident.
Reduce Indentation: When this option is enabled, the horizontal indentation for parented nodes in the Timeline is reduced to optimize the amount of space taken in the Timeline. When you have a cut-out character and there is a long cascade of parented nodes, you can enable this option so the Timeline (left side) does not have expand too wide to see all your nodes.
|Paste/Drag & Drop||
Add Keyframes at Beginning and End: Copies and pastes a set of frames that includes an interpolated sequence between two keyframes, but only extracts a partial section. Under normal circumstances, cutting and pasting a function without either the start or end keyframe would render the function null. This option caps the partial function with a new keyframe when you perform the paste.
Overwrite exposures and keyframes during drag and drop:When enabled, dragging and dropping drawings and keyframes in the Timeline view will overwrite the drawings and keyframes between the selection and the destination, as if the selection "wiped" everything on the way to the destination.
NOTEWhether this option is enabled or not, dragging and dropping a selection of drawings will always overwrite the drawings at the destination with the drawings in the selection. This option only changes what happens with the drawings between the selection and the destination.
Create Key Exposure: When enabled, changing the drawing at the current frame using the Drawing Substitution panel of the Library view will always create a key exposure at the current frame, even if the drawing is the same as the drawing in the previous frame. If disabled, a key exposure is only created if the drawing at the current frame is different from the drawing in the previous frame. If the drawing at the current frame is the same as the drawing in the previous frame, the exposure of the drawing in the previous frame is extended over the current frame.
