Adding a transition

We are going now to add a transition between two clips. Transitions are normally used to smoothly change from one clip to another (or from one scene to another). Some transitions can be used also as video effects (Picture in Picture, for example). These powerful features are explained in detail in this page, but for the purpose of this quickstart guide, we'll focus on an easy one, the crossfade transition (but see the warning at the top of this page!)

Before start, be sure that you have your two videoclips in tracks #1 and #2. Also, move (as explained before) the title clip that we've created previously to the start of track #0.

If we want to apply a transition, we need to overlap the required clips in different tracks. So first thing to do is to move the clip in track #1 to overlap with the title in track #0, let say by 2 seconds.

To better control this overlap you can change the timeline zoom using the viewer tool Image:Timeline_scale.jpg. Click on the magnifying glass and select a small scale or click on the ruler and drag left.

Once done, click on the title clip and press the right mouse button. In the context menu select Add transition -> Crossfade. A yellow bar will appear between the clips in tracks #0 and #1 indicating your transition has been added to the project.

At this point your screen should look like this one:

To have a real time view of how your transition works, you can click the seek marker Image:Seek_marker.jpg and drag it over the transition area. If everything is OK, you should see in the "Timeline Monitor" how the title clip dissapears at the same time the video clip is displayed.

To edit a transition and change parameters, you can double click on it (the yellow bar). In this way, it will become red and the focus in the "Project Panel" will change to the "Transition tab". In this tab you'll be able to change the transition parameters if needed.

As the Crossfade is an easy transition, the only parameters you can change are the transition direction and the track where it applies.

If the Invert direction parameter is selected, the upper track clip is shown first and the transition is applied until the view changes to the lower track clip. If the parameter is not selected, then the direction is the other way round.

The track to apply the transition is normally the next track after the one where we created the transition. But you can change this behaviour by selecting others in the Track Selection List. This is a powerful feature for advanced transitions, but for the moment we'll not use, so be sure your selection is Automatic – Use next video track.

You can play now creating a new transition between clips in tracks #1 and #2 in the same way as explained above.

Comments

There is no longer a crossfade transition. I believe that this documentation is a hangover from 0.5:
