# Strobing a Clip

Use the Strobe tool to create a clip that repeats a specified number of frames or fields without changing the duration of the clip. The repeated frames or fields replace the original frames or fields in the clip.

You can also create a film strobe. Creating a film strobe is useful for simulating a 3:2 video-to-film pulldown.

TipOnce you create a film strobe, add noise to the clip or colour correct it to produce a more authentic film look.
NoteWhen you create a film strobe, the duration of the clip is not affected. To convert the clip to 24 fps, use the Remove 3:2 option.

To strobe a clip:

1. With Video selected from the A/V Tools box, click Strobe.

   The Strobe controls appear.
