■ Setting Up a Composite 23
and that interlaced video is imported into After Effects, you can remove the 3:2 pulldown
and thus return the motion picture footage to 23.976 fps, which is close to its original 24
fps. This process is commonly referred to as inverse telecine. To apply inverse telecine, open
the Interpret Footage dialog box, set the Separate Fields menu to the appropriate field domi-
nance, and click the Guess 3:2 Pulldown button (see Figure 1.21). The program identifies
the style of pulldown and removes the duplicated frames. (Different pulldown styles repeat
the original film frames in different patterns.)
Figure 1.21 The Fields And Pulldown
section of the Interpret Footage dialog
box. The WSSWW listed by the Remove
Pulldown menu is the identified pulldown
style, where W indicates a whole frame
and S indicates a split frame. Split frames
are composed of two neighboring whole
frames.
Tips & Tricks: 24Pa Pulldown
After Effects includes a Guess 24Pa Pulldown button in the Interpret Footage dialog box. This is
designed to remove the pulldown created by 24p Advanced video systems, which record 24 pro-
gressive fps within a 30 fps interlaced video format.
Nuke Scripts
Nuke composites are called scripts. To create a new script, choose File → New from the
main menu bar. (For a review of Nuke panes and menus, see the introduction.) To edit the
script’s global properties, choose Edit
→ Project Settings. In the properties panel, the Frame
Range parameter determines the duration, the Fps parameter sets the frame rate, and the
Full Size Format parameter establishes the composite resolution. (A Nuke parameter is any
property with a slider, numeric cell, or check box.)
Importing Files
To import footage into a Nuke script, create a Read node. To do so, RMB+click in the Node
Graph and choose Image
→ Read from the menu. (Throughout this book, the RMB+click
technique is used almost exclusively when creating new nodes.) You can also LMB+click
the Image button at the top of the left toolbar and choose Read from the menu. Once the
Read1 node exists, its properties panel opens in the Properties pane. If the properties panel
is not visible, double-click the Read1 node in the Node Graph. You can browse for the foot-
age by clicking the File browse button (see Figure 1.22). Nuke automatically recognizes
image sequences and represents them with the following syntax:
name.padding.extension.
Padding indicates the number of numeric placeholders used for the sequence numbering.
This is encoded as
%01d, %02d, %03d, and so on. %02d, for example, signifies that there are
two placeholders, which creates
01, 02, 03, and so forth. Extension is the three-letter file
format code, such as
tga.
