3. Fancy Filter Tricks, Part 1
I was going to call this exercise "Combining Multiple Filters," but how boring is that? In this exercise, you will learn how to combine multiple filters to create an effect, reorganize filters to change an effect, create a filter stack you can apply to other clips, and remove attributes from a clip.This is an exercise in learning a technique, so you'll need to use only one clip.
| 1. | If Final Cut is not running, start it and open Chapter 11 Lesson. Double-click Seq Video Fancy Filter 1 to load it into the Timeline.[View full size image] | | 2. | Although you can create these effects anywhere you wish in the clip, if you want your screens to match mine, position the playhead on the second marker. | | 3. | Select MS Brown coat in the Timeline, then choose Effects > Video Filters > Border > Bevel. Double-click the clip to load it into the Viewer, then click the Filters tab.   | | 4. | Click the color tab in the Bevel filter and select a light golden color. (Oh, no reason, I just like the color gold.) Notice that the bevel matches the color you selected. Twirl the Bevel filter up by clicking the small down-pointing triangle. This provides more room to work in the Filters tab.  | | 5. | Next, apply a second filter to this same clip. Choose Effects > Video Filters > Blur > Gaussian Blur. This blurs the image. (By the way, this is the only filter to use when you want to blur a clip. The other blur filters look pretty tacky.) For the purposes of this exercise, crank the Radius up to 20.  | | 6. | Finally, apply a third filter to this same clip. Choose Effects > Video Filters > Image Control > Desaturate. This removes all the color from the image.What you have created is a colored bevel around an image, then you blurred the whole image, including the bevel, and removed all the color from the image.Here's the point of this exercise so far: you can combine multiple filters to create effects not possible with one filter alone. However, and this is an even more important point, the order of your filters directly affects your effect. Watch this…   | | 7. | Click and drag the title of the bottom filter (Desaturate) to the top of the filter stack.See the change? The image is desaturated first, then the color bevel is added, then the whole image is blurred.
NOTE | Filter Processing
Final Cut processes filters from the top down. In other words, the topmost filter is processed first, then the results of that filter are processed by the next filter down, then those results are processed by the next filter, and so on from top to bottom.This means you can change an effect simply by changing the stacking order of your filters. And you move filters by dragging their names up or down the list.There is no limit to the number of filters you can apply to one clip, though after you combine more than one or two filters, Final Cut will need to render your effect, rather than play it in real time. |
   | | 8. | One more time to make the point. Drag the bottom filter, Gaussian Blur, to the top and watch how the new order changes the image. | | 9. | Just as you can create a Favorite filter, you can also create a Favorite filter stack (or group of filters, such as you've been working on here). To create a filter stack, select the clip containing the effects you like (MS Brown coat). Choose Effects > Make Favorite Effect. | | 10. | Choose Browser > Effects tab > Favorites folder. Inside you will see a folder labeled with the name of your clip and (Filters). This is now a Favorite effect that can be applied to other clips.
WARNING | Don't Open a Filter Stack
A filter stack is represented by a folder in the Effects tab of the Browser. But be careful not to double-click this folder to open the stack. Why? Because the Browser sorts files in alphabetical order. Watch… If you want to see what's in a filter stack, twirl down the folder. That maintains the order of the filters. If you open the folder by double-clicking it, the Browser sorts all files in alphabetical order, thus totally rearranging your effect. |
There's more to learn about filters, but, first, let me show you another way to remove attributes from a clip. Its called, ta-da! Remove Attributes. | | 11. | Select MS Brown coat and choose Edit > Remove Attributes.Remove Attributes is smartit looks at the clip to determine what effects have been applied. In this case, you have only added filters, so only the Filters option is selected. If you had applied other effects, other options would be selected. The benefit to using this window is that you are able to remove some effects without removing all of them. | | 12. | In this case, leave Filters checked and click OK.All filters have now been removed from the clip. And this is a good thing, because you are about to work with this same clip in a new way. | | 13. | That's it for this exercise.Don't save your work, unless you feel the need. Quit Final Cut if you want to take a break. Otherwise, leave this sequence open; you'll use it in the next exercise. |
