Apple Final Cut Pro 6 - Manual (Page 1827)

344 Part IV Settings and Preferences
Compression Tab
The settings available in the Compression tab depend on the codec chosen from the
Compressor pop-up menu.
Motion Settings
 Compression type: This pop-up menu has the same codec choices as the Compressor
pop-up menu in the QuickTime Video Settings section of the Preset Editor window.
 Frames per second: Choose a value to specify the number of frames captured per
second. This value is the same as the FPS field in the QuickTime Video Settings
section of the Preset Editor window.
 Key frame every N frames: Even though QuickTime supports temporal compression
using keyframes and in-between frames, you should not select this option
when capturing.
 Limit data rate to N KBytes/sec.: Some codecs allow you to enter a target data rate for
your compressed QuickTime file. The codec may use a combination of spatial (per
frame) and temporal (across multiple frames) compression to try to reach your target
data rate. Be aware of your frame size and frame rate so you don’t set an impossible
goal and get disappointing quality in the visual image. This is identical to the Limit
Data Rate field in the QuickTime Video Settings section of the Preset Editor window.
Click Compression.
Specify the
desired settings.
