The Filmmaker’s Guide to Final Cut Pro Workfl ow<br />

The following chart shows several popular video formats and the sizes that should be used to create<br />

graphics in a pixel-based system like Photoshop. Several need to be scaled to a new size before<br />

importing into Final Cut Pro.<br />

Video Format: Design Graphics at: Scale Image to:<br />

4 × 3 Web Video 640 × 480 Scale to fi nal output in FCP<br />

DigiBeta MPEG IMX 720 × 486 No need to scale<br />

DigiBeta at 16 × 9 853 × 486 720 × 486<br />

SD DV formats at 4 × 3 1280 × 960 720 × 480<br />

SD DV formats at 16 × 9 852 × 480 720 × 480<br />

HD 1080 i or p 16 × 9 1920 × 1080 No need to scale<br />

Table 8.1 Video Format Size Chart<br />

To create a title or graphic in Photoshop, select New in the File menu. In the dialogue window, enter<br />

the horizontal and vertical size from the Video Format Size Chart in pixels. To scale the fi nished<br />

title, select Image Size in the Image menu. In the dialogue, enter the scaled size in the horizontal<br />

and vertical in pixels.<br />

HD images use square pixels and so do not have these problems or require rescaling. They can be<br />

created in their native resolution and will have the proper proportions on the computer monitor. The<br />

HD image uses either 720 or 1,080 horizontal lines, and 1,280 × 720 or 1,920 × 1,080 pixels. It can<br />

be either progressive or interlaced and its standard aspect ratio is 16 × 9.<br />

Alpha Channel<br />

An alpha channel is a fourth channel in the image-defi ning areas of the image that are transparent.<br />

This is essential if you want to superimpose titles over picture. It is also a great way to reduce contrast<br />

to improve the look of the titles (more on this later in this chapter).<br />

Some titling systems automatically create this alpha channel. The Final Cut Pro titler creates an alpha<br />

channel. Any title with an alpha channel can be simply placed in video 2 with the background video<br />

in video 1 and the title will automatically be superimposed over the video.<br />

When creating titles in Photoshop you must set up your own alpha channel. When creating a new<br />

title, set the background to transparent as shown in Figure 8-3. Photoshop will now show as a gray<br />

checkerboard background. Lay out the title and save it as a Photoshop fi le. This will import directly<br />

into Final Cut Pro with an alpha channel that will allow the title to be superimposed over video, and<br />

you can control its opacity to control the contrast.<br />

Colors are a problem as well. The computer uses RGB colors, NTSC uses a different “color space”<br />

called YUV. NTSC cannot reproduce many of the colors that can be displayed on the computer<br />
