2. Tap the Edit button at the bottom of the screen.

3. Drag the clip to position the playhead where you want to trim or split the clip.

   • Trim the clip from the start to the playhead: Tap the Trim from Start button .

   • Split the clip at the playhead: Tap the Split button .

   • Trim the clip from the playhead to the end: Tap the Trim from End button .

You can shorten a clip, or extend the length of a previously shortened clip, by dragging the trim handles at the edges of the clip. Use this method when you’re not sure exactly how much you want to shorten or lengthen a previously shortened clip.

   Tip: If you’re not sure how much to shorten or lengthen the clip, drag the trim handle back and forth to experiment with different clip lengths, then release the trim handle when you’re happy with the length.
