5. Key frame control allows you to control the placement of key frames for
compression schemes that support interframe compression (such as Cinepak).
This can help the compression algorithm emphasize important segments.
6. Cropping displays a dialog box where you can modify the frame dimensions of
the video. (See page 222 for more details.)
Note: For more on understanding key frames and compression, see the Appendix,
page 393.
VIDEO SAVE OPTIONS: GENERAL TAB
1. Data track specifies whether to create a video file of the video track only, or both
the video and the accompanying audio track. (To save the audio track only click
the File: Create - Audio File command.)
2. Frame rate specifies the frame rate to use for the resulting video file. For
example, NTSC video is typically 29.97fps. See your capture board's manual for
specific frame rate advice.
3. Frame type select between saving your work as field-based or frame-based
video files. Field-based video stores video data as two distinct fields of informa-
tion for each frame. If your video is only for computer playback, you should save
your work as frame-based.
