Pinnacle Liquid Edition 6 for Windows

Although the single-track edit system is indisputably the more flexible of the two approaches to NLE, you don't get something for nothing.

Because of the sheer power you wield by being able to place a transition on any track you want, you'll find that you have rules to follow. Liquid Edition needs you to follow these if it is to fully understand exactly what you want it to do. These rules are not that complex, and if you take certain precautions, you can avoid the confusion that comes with learning how to use the single-track edit system.

The most important thing to know about the rules is to make sure you have enough available handles (on both clips) and that you know how to adjust a clip if you don't have enough.

Using available handles

A handle is the bit of a clip you don't see. It's the bit that a transition needs in order to have a tangible piece of video with which it can work. It's also one of the more challenging aspects of single track editing, particularly for users transferring from the easy A/B roll system. But in fact handles are simple enough once you know exactly what you are looking for.

To visualize the handle of a clip

Place any video clip in the Source Viewer.

Insert a mark-in a few seconds after the start and a mark-out point a few seconds from the end on the Source Viewer Timeline (see Chapter 6 for details on this).

The first handle of the clip is the gap between the start of the media clip and the mark-in point. The other handle is the gap between the mark-out point and the end of the clip (Figure 8.4).

Figure 8.4. Mark-in and mark-out points added to a clip create handles at the start and end.

Send this clip to the Timeline using the insert arrow twice so that the clip appears as shown in Figure 8.5, the invisible areas before and after the mark-in and mark-out pointsthe handlesare used by the transition.

Figure 8.5. Two clips on the Timeline waiting for a transition.

However, if you try to use a clip whose mark-in and mark-out points are the same as its clip-in and clip-out pointsin other words, its natural lengthyou'll encounter a problem (Figure 8.6).

Figure 8.6. Liquid Edition uses the clip-in and clip-out points of a media clip that has no mark-in and mark-out points.

Repeat the last set of instructions but set the mark-in and mark-out points at the start and end of the clip respectively. This creates a Timeline that appears to be exactly the same as Figure 8.5, but you'll find that attempting to place a transition isn't possible. Instead, if you are dragging and dropping a transition, you see the error message "not enough media available to place transition" (Figure 8.7).

Figure 8.7. The error message you see if no handles exist for a transition to latch onto.

Worse still, if you're using the Add Dissolve button , nothing happens and no error message is displayed. This is because a transition needs these overlapping pointsa set of handlesto which it can attach itself. Without them, the transition can't work.

If you don't have enough handle length

In Chapter 6, I recommendedperhaps a little controversiallythat you use embedded audio wherever possible to avoid audio sync issues. To avoid transition problems, I recommend that you alter a setting in Liquid Edition that prevents transitions from being placed if you don't have enough available handle length.

This means that the transition can appear even if it doesn't work correctly, allowing you to continue working without constantly worrying about available handle lengths. I cover trimming these clips so that they work with transitions in the "Trimming Associated Clips" section later in this chapter.

To turn off "Restrict dragged Transitions to available handles"

Right-click the Timeline to bring up the Timeline properties dialog box.

Switch to the General tab and uncheck the box next to "Restrict dragged Transitions to available handles" (Figure 8.8).

Click the check mark to accept this change.

Tip

Once you make this change, you'll have to manually trim any clips that don't have enough handle space. See the "Trimming Associated Clips" section later in this chapter.
