Seconds or Frames

Select either Seconds or Frames to set the Timeline Editor window to display time in either seconds or frames.

Duration Mode

Use the Duration Mode to set whether the duration of the Timeline Asset extends to the end of the last clip (Based On Clips), or extends to a specific time or frame (Fixed Length). When the Duration Mode is set to Fixed Length, use one of the following methods to change the length of the Timeline Asset:

  • Select the Timeline Asset in the Project window and use the Inspector window to set the Duration in seconds or frames.

  • In the Timeline Editor window, drag the blue marker on the timeline. The blue marker indicates the end of the Timeline Asset. A blue line indicates the duration of the Timeline Asset.

Frame Rate

Select one of the options under frame rate to set the play speed of the Timeline Asset. The overall speed of the Timeline Asset accelerates or decelerates based on the number of frames per second. The higher the number of frames per second, the faster the entire timeline plays. The following frame rates are supported: Film (24 fps), PAL (25 fps), NTSC (29.97 fps), 30, 50, or 60.

Show Audio Waveforms

Enable Show Audio Waveforms to draw the waveforms for all audio clips on all audio tracks. For example, use an audio waveform as a guide when manually positioning an Audio clip of footsteps with the Animation clip of a humanoid walking. Disable Show Audio Waveform to hide audio waveforms. Show Audio Waveforms is enabled by default.

Snap to Frame

Enable Snap to Frame to manipulate clips, preview Timeline instances, drag the playhead, and position the playhead using frames. Disable Snap to Frame to use subframes. Snap to Frame is enabled by default.

For example, when Snap to Frame is disabled and you drag the Timeline Playhead, it moves the playhead between frames, the format of Playhead Location displays differently depending on whether the timeline is set to Seconds or Frames:

  • When the timeline is set to Frames, the Playhead Location field shows frames and subframes. For example, 8 frames and 34 subframes displays as 8.34.

  • When the timeline is set to Seconds, the Playhead Location field shows seconds, frames, and subframes. For example, 6 seconds, 17 frames, and 59 subframes displays as 6:17 [.59].

Manipulating clips, previewing Timeline instances, and positioning the playhead at the subframes level is useful when attempting to synchronize animation and effects with audio. Many high-end audio processing software products create audio waveforms with subframe accuracy.

Edge Snap

Enable the Edge Snap option to snap clips during positioning, trimming, and creating blends. When enabled, clips are snapped when the start or end of a clip is dragged within 10 pixels of the start or end of a clip on another track, the start or end of a clip on the same track, the start or end of the entire timeline, or the playhead. Disable Edge Snap to create accurate blends, ease-ins, or ease-outs. Edge Snap is enabled by default.
