Adding a Filter

Once you understand the basic concept of using filters, actually applying them is easy and can be achieved by drag and drop.

Tip

• Some filters have no value until you open the editor and adjust some of the parameters, and therefore, they show no immediate change to the clip. See "Taking Filters Further" later in this chapter for more information on this.

To apply a filter

1.	Place a clip on the Timeline and if the Project Browser isn't yet open in the Timeline, click the Open Project Browser in Timeline button .
2.	Click once on the Lib tab to show the effects Liquid Edition has to offer (Figure 9.6). Figure 9.6. The effects tree displayed in the Project Browser. Dual-screen users will probably have the Project Browser open on the second monitor; in this case the tab will be marked Library.
3.	Do one of the following: Open the Realtime Clip FX folder if you intend to add Realtime filters. Open the Classic Clip FX folder if you intend to use non-Realtime filters.
4.	Once you have selected the type of filter you want, click a Rack to display its contents. Premiere Translation Many of the filters used in Premiere are found in Liquid Edition; many even have the same names. However Liquid Edition refers to filters as Clip FXsthat is, FXs that you apply to clips. Other than that minor difference, the Clip FXs of Liquid Edition behave in a similar fashion to the filters in Premiere.
5.	Highlight the actual filter you want by clicking it, and apply the filter to the Timeline by doing one of the following: Drag the filter into the Timeline and release the mouse button when the filter is over the clip (Figure 9.7) Figure 9.7. Dragging a filter from the Project Browser to the Timeline. Right-click the filter and select Copy (Figure 9.8). Then right-click the clip and select Paste > Clip FX from the menu (Figure 9.9). Figure 9.8. Applying a filter using the copy and… Figure 9.9. …paste method.
6.	To remove this filter, do one of the following: Right-click the clip in the Timeline and select Clip Undo from the menu (Figure 9.10). Figure 9.10. Deleting a filter using Clip Undo. Right-click the clip in the Timeline and select FX Properties from the menu. Then highlight the filter you want to delete and click the Trash can (Figure 9.11). Figure 9.11. Deleting a filter via the Clip FX Properties dialog. Right-click the purple line running along the top of the clip and select Delete from the menu (Figure 9.12). Figure 9.12. Deleting a filter via a right-click on the purple FX line.

Tip

• If you are dragging a filter to the Timeline and you see the message "No Filter Target," then you don't have the mouse cursor over a valid media clip.

Clip Undo

The Undo function for filterslike the Undo function for audio keyframesis a separate entity from the Undo command you normally use.

If you add a filter to a clip on the Timeline and then use Ctrl+Z or the Timeline Undo key, then an Undo occurs on the Timeline, but the filter remains firmly on the clip. In this case, I advise you to click the Redo key to redo whatever it is that you've accidentally undone.

This becomes slightly more complex when you're dealing with filters you've added to tracks and to clips in the Project Browser. To keep this from frying your brain early on in the chapter, I've listed the removal method in the last step for each of the three application techniques.
