Synchronizing video clips

To make the images in the different clips comparable, you need to synchronize their action so that you are comparing relatively similar action within the performances. You can synchronize video clips by using the key positions (see next section) or by using the timeline(s).

Method A: using the Timeline

1.	Load two clips in split-screen (see sections Loading multiple clips and Display modes)

2.	Click anywhere in the clip displayed on the left of the screen (most likely clip A). A blue timeline shows underneath the screen. Note that timelines are color-coded according to the display screen; blue corresponds to letter A.

3.	Drag the Playhead to the position where the clip should be synchronized (e.g. at the impact)

4.	Click the clip on the right of the screen (most likely clip B). A yellow timeline replaces the blue one.

5.	Click and drag the yellow timeline forward or backward (NOT the playhead) until the two clips are synchronized (e.g. when both clips are at the impact).

Use the [shift] + [left] (or [shift] + [right]) arrow to fine tune the synchronization. This moves the timeline one frame backward or forward.

To play the synchronized clips, click on the Stop button to move the Playhead to the beginning of the play range and click the Play button.


Method B: using the Timline tab

You can use the Timeline view to synchronize clips. Click on the corresponding tab to display this view.

The synchronization process is the same as described above except that you do not need to click a clip to select the blue or yellow timeline. You can directly click on a timeline to select it. This view also allows for quick re-synchronization. Simply move the playhead to a new position and adjust the timelines to re-synchronize at the new position.
