Flash after effects sự kết hợp chuyên nghiệp phần 4 Select Insert > New Symbol. Enter mcTextAnimation for the name and make17. sure that the type is set to Movie Clip. Click OK. The Timeline for the new movie clip appears. Highlight the first blank keyframe18. and select File > Import > Import to Stage to open the Import dialog box. Choose the SWF file you created in After Effects. Click Open. Figure 3.13: Import the SWF file created in After Effects into a movie clip in Flash. When the SWF file is imported into the movie clip, it appears as a series of19. keyframes. Scrub through the Timeline to see the animation. Go to the Library. There is a graphic symbol for each letter in the text animation. Double-click on a graphic symbol and you will see that the letter form is a vector shape. Figure 3.14: The imported SWF file appears as a series of keyframes in the Timeline and each letter appears as a graphic symbol in the Library. Let’s add to this animation. First, insert a frame (F5) at frame 85 (Figure 3.15).20. This will hold the text on the screen long enough to read it. Figure 3.15: Insert a frame (F5) at frame 85. This will extend the text’s time on the screen to allow the viewer to read it. 71Exporting SWF Files Next, create a spiral-out sequence using the exact same keyframes just in21. reverse order. To do this: 3 Select the keyframes from frames 1 to 45. 3 Select Edit > Timeline > Copy Frames. 3 Click on the empty cell at frame 86. Select Edit > Timeline > Paste Frames. 3 Highlight the pasted keyframes. Select Modify > Timeline > Reverse Frames. Figure 3.16: Create a spiral-out sequence by copying and pasting the frames at the end of the Timeline. Then reverse the frame sequence. Close out of the movie clip and return to the root Timeline. Click on the New22. Layer icon at the bottom of the Timeline panel. Rename the layer to text. Click and drag the mcTextAnimation symbol from the Library to the Stage.23. Go to the Properties panel and set the X and Y position to 0 (Figure 3.17).24. This aligns the registration point to the upper left corner of the Stage. Since the composition in After Effects was set to the same dimensions as the Flash Stage, the text will be positioned in the center of the Flash movie. Figure 3.17: Set the X and Y positions to 0 to center the text on the Stage. Save and publish your movie. The text spirals in and then out. You may want25. to add a “stop” action on the last frame of the text movie clip. Note that the final file size for the SWF file is around 8 KB. That is even smaller than the text animation SWF file exported from After Effects (9 KB). Flash does provide better compression than After Effects when exporting SWF files. Creating and exporting complex text animation as a SWF file is rather easy to do in After Effects. This exercise introduced you to text layers and animation presets. There is much more that you can do with these. In fact, Chapter 5 devotes itself entirely to creating and animating text in After Effects.72 Chapter 3: From After Effects to Flash Exercise 2: Export Illustrator Animation as Flash SWF Let’s export one more SWF file from After Effects. For this exercise, you will use footage created in Adobe Illustrator to export a SWF file for the Flash Player. The final SWF file will only contain vector art, keeping the file size small. Create a new project in Adobe After Effects.1. Import the footage file. Double-click inside the Project panel. This opens the2. Import File dialog box. Locate the SpringLogo.ai file inside the 01_Footage folder in 01_SWF/Chapter_03. Select the file. Figure 3.18: Import the Adobe Illustrator file into the Project panel. Before you import, choose Composition – Cropped Layers as the Import type3. in the Import dialog box. Each layer will import with their original dimensions. This will make it easier to animate in the Comp Window. Click OK. Double-click on the SpringLogo composition in the Project panel to open4. it in the Timeline and Composition panels. Select Composition > Composition Settings. Make sure the duration of the5. composition is set to five seconds (05:00). Click OK. If you added more time to the original duration, you will need to zoom out6. the Timeline to view the entire composition. To do this, click and drag the Zoom slider at the bottom of the Timeline all the way to the left. Figure 3.19: Zoom ...
