Modifying Filters in the Timeline

Now that the new video clip has been added to the project, let's enable the filters and see how the two video clips look when played in the Canvas. While we're at it, we'll enable all of the filters in the project.

To enable the filters, you'll need to click the Filter enable/disable buttons in the Layer list. It's also a good idea to set the Show/Hide Behaviors and Show/Hide Filters buttons to Show so you can see all of the different elements in the Timeline.

1.	Click the Stills layer disclosure triangle to view the contents of the Stills layer.
2.	Click all three of the Filter enable/disable buttons in the Layer list to enable the filters for all of the objects in the Timeline. Filter enable/disable button
3.	Click the Show/Hide Behaviors and Show/Hide Filters buttons at the bottom of the Timeline tab to show behaviors and filters. The Show/Hide buttons appear darker gray when they are in the Show position.
4.	On the Timeline Layer list, click the surf_1_SD_jpg disclosure triangle to see all of the Posterize filter. Then play the project once in the Canvas. The Posterize filter still looks great on the first video clip, but it would be even better if it were used on both video clips. You could copy and paste the filter to the second video clip, or just move the filter to the Video layer so it applies to all of the contents in the Video layer. Let's try it.
5.	On the Layer list, drag the Posterize filter upward from the surf_1_SD_jpg object and drop it on the Video layer. The Posterize filter appears at the top of the Video layer, and a purple Posterize region appears on a track below the Video track in the Timeline. The Posterize filter needs to be extended to cover the full duration of the project.
6.	Press the End key to move the playhead to the end of the project; then press O to extend the Out point of the Posterize filter to the playhead.
7.	Press the spacebar to play the project. The Posterize filter is definitely over both video clips. However, the Posterize filter is so strong on the second clip that you can't tell what you're looking at. Let's modify the Posterize filter in the Dashboard to take it down a notch or two so you get the effect and can also recognize what you're looking at in the video clip.
8.	Press D to open the Posterize Dashboard, if it's not already open; then drag the Levels slider toward the right to 11. Feel free to modify the Posterize level to whatever you think looks best.
9.	Click the Video layer disclosure triangle to collapse the layer and hide the contents.
10.	Press Cmd-S to save your progress.
