# Working with Multiple Subtitle XML Files for Clip Versioning

You can add multiple Subtitle XML clips to a timeline, then mute all but the layer you want to process. With this method you can quickly version a clip.

To work with multiple Subtitle XML layers in the timeline:

1. Stack multiple Subtitle XML clips onto layers of a timeline.
2. Hold Ctrl and click the track identifier on all the layers you want to mute.
   NoteA muted layer has a yellow track indicator.
3. Drag the timeline onto the Clip Library box to save the clip.

   The clip is saved with only the selected subtitles appearing.

4. Repeat steps 2 and 3, alternating the subtitles that appear. To show a muted layer, hold Ctrl and click its track identifier again.
   TipThe top layer cannot be muted.
