Editing with the Timeslice Tool

You can use the Timeslice Tool to make time-based selections. Unlike selections of multiple clips with the default Selection tool (which can only select whole clips), Timeslice tool selections are entirely time-based. This means you can use the Timeslice tool to select portions of clips or portions of multiple clips. You can also easily move and adjust the size of a Timeslice tool selection and add or remove entire tracks from the selection. This is most important for processing effects.

Note: The currently active channel selections are the only channels affected by the Timeslice tool.

Use the Timeslice tool to select any combination of the following:

To make a selection with the Timeslice tool
  1. Click the Timeslice tool at the top of the Timeline (or press W).

  2. Drag across any portion of the Timeline to make a Timeslice selection.

    A Timeslice selection rectangle appears over the area.

To select a portion of a clip with the Timeslice tool
  1. Click the Timeslice tool at the top of the Timeline (or press W).

  2. Drag across any portion of the clip with the Timeslice tool.

    A Timeslice selection rectangle appears over the portion of the clip and the File Editor tab displays the same selection in its waveform view.

To adjust the size of a Timeslice selection
Do one of the following:
  • Drag any of the four edges of the selection to extend or shorten that side of the selection rectangle.

  • Shift-click any track you want to include in the Timeslice at the opposite end of the area you want to select.

To move a Timeslice selection
  • Click the center of the Timeslice selection, then drag it to a new location in the Timeline.

To add a noncontiguous track to a Timeslice selection
  • Command-click anywhere in the track.

    Note: You can add tracks that are not adjacent to or contiguous with the selection.

To remove a track from a Timeslice selection
  • Command-click anywhere in the track.

You can select a master Timeslice that includes the audio content and the envelopes of all tracks, busses, and submixes, including the video’s audio track. (Only a master Timeslice contains busses and submixes.)

To make a master Timeslice selection
  1. If the Timeline is in Select Only Clips mode, enable Select Envelope Points With Clips mode (or press Option–E).

  2. Using the Timeslice tool, drag in the selection bar of the video track, located above the Time ruler.

Cutting, Copying, and Pasting Timeslices

You can cut or copy a Timeslice and paste it at a different position in the Timeline.

Make sure the Timeline is in Select Envelope Points With Clips mode if you want envelopes to be cut or copied along with a Timeslice. Timeslice copies do not create extra envelope points around the perimeter of your selection. To ensure predictable results when pasting Timeslices, it is a good idea to create extra envelope points at the boundaries of your Timeslice selection.

To cut a Timeslice
  • Select the Timeslice, then choose Edit > Cut (or press Command-X).

    If you want envelopes to be cut along with your Timeslice, enable Select Envelope Points With Clips mode (or press Option–E if the Timeline is in Select Only Clips mode).

To copy a Timeslice
  • Select the Timeslice, then choose Edit > Copy (or press Command-C).

    If you want envelopes to be copied along with your Timeslice, enable Select Envelope Points With Clips mode (or press Option–E if the Timeline is in Select Only Clips mode).

To paste a Timeslice
  • Set the playhead at the position where you want to paste the Timeslice, then choose Edit > Paste (or press Command-V).

    The topmost track of the Timeslice is pasted in the currently selected track, and any remaining tracks are pasted in the tracks below the selected track. If there is no track selected, the Timeslice is pasted on the first track of the project. If not enough tracks exist for the number of tracks in the Timeslice, a dialog appears asking if you want to create additional tracks.

To paste insert a Timeslice
  • Set the playhead at the position where you want to paste insert the Timeslice, then choose Edit > Paste Special > Paste Insert.

    If the Timeslice is from a single track, it is inserted in the first selected track at the current playhead position. If the Timeslice is from multiple tracks, the Timeslice is inserted in the first selected track, and any remaining tracks are pasted in the tracks below the selected track. In both cases, audio at the position of the playhead is rippled along the Timeline the length of the pasted audio. If not enough tracks exist for the number of tracks in the Timeslice, a dialog appears asking if you want to create additional tracks.

    Note: The Paste Insert command works only with Timeslices.

    Any tracks that you want to be rippled must be included in the original Timeslice selection.

    Important: Because the Paste Insert command shifts audio, care must be taken to ensure your project remains in sync.

Deleting the Contents of Timeslices

You can delete the contents of a Timeslice if you want.

To delete the contents of a Timeslice selection
  • Select the Timeslice, then choose Edit > Delete (or press the Delete key).

Changing the Timeslice Selection Area

You can change the height or the length of a Timeslice selection area to include more of the Timeline, either graphically or numerically.

To extend the Timeslice selection area graphically
  • Shift-click any track at the point to which you want to extend it.

To change the In point, Out point, or duration of a Timeslice numerically
  1. Make a Timeslice selection in the Timeline.

    The Details tab displays Timeslice controls.

  2. In the Details tab, type a new value in the In value slider, the Out value slider, or the Duration value slider.

    Figure. Details tab.
  3. Press Tab or Enter to confirm the new value.

Note: To the right of the Timeline transport controls is the Selection Length value slider. When a Timeslice is active, the Selection Length value slider shows the length (duration) of the active Timeslice. You can use this value slider the same way you use the Duration value slider in the Timeslice section of the Details tab.

For more information on how to use value sliders, see About Changing Values and Timecode Entries.
