# Gaps

Gaps are empty spaces between elements in an edit sequence. When you apply Timeline FX to a gap, you create a gap effect,.

While Timeline FX can only be applied to a clip, the effects applied to gaps are independent of all media. They effect the media under them.

Gaps usually appear in the following places:

- The empty space between media elements on a video track.
- An empty video track.
- The space between cut points on an empty video track. Cut points are useful for containing a gap effect applied to an empty video track. The areas to either side of the cut points are also gaps.

Gap effects are not restricted by in points, out points, cuts and transitions, so they are easily trimmed, moved and duplicated. You can trim a gap effect over the entire duration of the video track regardless of the underlying cut points.

You can also freely edit cuts and transitions between elements on video tracks under the gap effect. You can cut an element, add a transition at the cut point, and then replace the incoming element without affecting the gap effect. In addition, gap effects can be copied and placed over different media in the timeline.
