Preparing Frames for Rotoscoping

To do frame-by-frame rotoscoping in Photoshop, you need to convert the movie to separate editable frames. By opening the movie in ImageReady, single layers and frames will be automatically created from the QuickTime movie footage.

In ImageReady, open the QuickTime movie clip you rendered out of After Effects (File > Open). You'll see a dialog box asking you to select some options (Figure 6.9). In this case, because we rendered only the portion we need to rotoscope, we'll select the From Beginning To End option. You may also select a range within a QuickTime movie to import.

Figure 6.9 Open the QuickTime movie sequence in ImageReady and import the entire clip to be rotoscoped.

ImageReady turns the image frames into individual layers that can be rotoscoped in Photoshop. Jump to Photoshop so that you can start the frame rotoscoping work (Figure 6.10), and save the new file as a Photoshop document.

Your File Really Isn't Too Big

When jumping back to ImageReady from Photoshop with a rather large multilayer file, you may encounter a recommended file size warning (40 MB maximum). Don't be alarmed—though you might be taken aback by the warning message,you can continue the process without interruption. (You may also choose to disable the warning message in the future).

Jump to Photoshop and perform the rotoscoping edits to each layer as necessary (Figure 6.11). See Chapter 7, "Rotoscoping Techniques with Photoshop," for more information on how to tackle this task. Once the editing is completed on all of the affected layers, save the Photoshop file and jump back to ImageReady.

Figure 6.11 Rotoscope the individual layers and jump back to ImageReady to export the rotoscoped movie.

You can now export the file as a QuickTime movie by selecting File > Export > Original Document and choosing the QuickTime Movie format. Once you click the OK button, a dialog box will appear to allow you to set the compression and color depth of the QuickTime movie. Because this movie needs to remain as pure and unadulterated as the original blue-screen frames, you will want to select None for the compression and choose the maximum color space.

Note: Alternatively,you may want to export single frames from ImageReady instead of a QuickTime movie. Select File > Export > Layers As Files or Animation Frames As Files.These sequenced image files can be opened in QuickTime Pro by selecting File > Open > Image Sequence. A dialog will appear,asking you to set the Frame Rate in frames per second. Because the original footage was 30 fps,you will want to match that exactly. Save the new movie as a noncompressed QuickTime movie file.

Check the QuickTime movie in real time to see if any frames require additional editing. Sometimes it's hard to tell if you are rotoscoping too close to the actors, which may cause some frame flickering. More on controlling this effect is found in Chapter 7.
