Apple Final Cut Pro 7 - Manual (Page 1799)

This chapter covers the following:
• Determining the Image Format for Still-Image Export (p. 1799)
• Exporting a Single Still Image (p. 1800)
• Exporting Image Sequences (p. 1801)
At many points during your project, you may need to export still images of your video
for graphics, posters, the press, email, or the web.
Determining the Image Format for Still-Image Export
Final Cut Pro uses the built-in QuickTime technology in Mac OS X to export still images.
Because QuickTime supports a wide variety of graphics (still-image) formats, nearly any
graphics format you need to export is supported.
If you’re exporting images for a website, JPEG is a good option because it compresses
images to a small size but maintains fairly high quality. If you want to export images
without compression, you can export TIFF or Photoshop files.
Note: If you need to export a sequence as a numbered image sequence (a collection of
still images), you’ll go through a slightly different process than simply exporting a single
still image.
Resolution of Exported Still Images
Exported still images are 72 dpi. This number cannot be changed during export and is
irrelevant for video and computer use. If you are exporting for print and you need to
adjust the dpi setting, you can do so in a graphics application such as Adobe Photoshop.
Bit Depth of Exported Still Images
Exported still images are always exported using 8 bits per pixel per color channel. For
example, an RGB TIFF or Photoshop file uses a total of 24 bits (3 channels x 8 bits per
channel) per pixel. If an alpha channel is included, the exported file uses 32 bits per pixel
(4 channels x 8 bits per channel).
