You can choose a blank clip by choosing 'Edit video clip' on the menu. Decide how long the clip will be by moving left and right. When you are happy, left click to continue. You must then choose the type of clip - a shape, a background, a particle, some text, or a tunnel effect.

You can apply numerous effects and movement to your initial clip type - including color changes, splines, rotations and scaling. To do this press 'Add Chase' in the current menu. So you now have two clip elements displayed on screen.
Highlight the clip element to be edited. You can edit thousands of different parameters, including the number of shapes in your scene, the layout of objects, the direction of rotations, the size of the main clip element - in fact you can take complete control of the visuals displayed on the screen. Scrolling left and right alters the value of the highlighted clip.

If you have left information on the Timeline you can make your video trigger off the notes on a music channel or a function key on your keyboard amongst other things. So, for example, you can make the background change every time a cymbal is struck. Or you can make an object change size with every beat of the song. The possibilities are endless.

Click on Global Settings. There are three parameter boxes with arrows on either side in the Global Settings panel.

If you toggle through the parameters in the top box you will see that you can set the visual effects to trigger off a specified audio channel (1-99).

If you edit the parameters in the middle box you can make your visuals trigger off -
1. Keyboard function keys
2. Sixteenths of the bar
3. Each beat of the song
4. The first beat of each bar
5. Random parameters.

The box at the bottom defines how the information on the Timeline is played.

1. The cursor can scroll from left to right and back again through each edited stage of the Timeline.
2. The cursor will 'step' through each edited position on the Timeline.
3. The cursor can swiftly ramp up through all the parameter changes and then drop back to the start of the Timeline.
4. The cursor will play the Timeline from one end to the other over the length of the video clip (as represented on the track screen).

The box to the right in the Global section has a slider that can be moved up and down to define the sensitivity of the trigger. Set it to the top for the most sensitive response to the trigger you have added.

The numbers 1, 2, 3 and 4 at the right of the Global section refer to the four video channels. This feature is only accessible from the DVE channel - the channel at the bottom of the video screen.

If you select one of the four numbers, the corresponding channel will be deactivated and not included in the current DVE effect.

Changing or editing an existing video clip will change it throughout the whole arrangement. Avoid this by selecting the Clone Video Clip option (while highlighting a video clip on the video track screen) and creating a new video clip modeled on the existing one. The background color of the icon will now have changed. Any changes you carry out will not be applied to other versions of the original video clip.

This function will automatically create a video for you - perfect if you have just written some music and want some impressive visuals to go with it.
Select 'Auto-generate video' from the Video Track menu. You will see there are two auto-generate parameter values that you can adjust before the calculations begin. Select 'Generate video' and MTV Music Generator will cook you up a video.
