1. Enable undo specifies the maximum levels of undo/redo allowed by Video Editor
(up to 99). As Video Editor allocates more memory for each level of undo/redo, you
may find that too high a level adversely affects performance. In such cases,
restrict the level to 3-4 only. You can, of course, choose not to have undo/redo to
maximize performance, but any editing done will be final.
2. Number of recently opened files specifies how many file names are stored in
the Recent History list found on the File menu.
3. Return to the first frame after playing returns any sequence in the Source and
Preview windows to the first frame after it has been played (like a CD player).
When left cleared, the sequence stops on the last frame in the sequence after
playing (like coming to the end of a tape in a VCR).
4. Use temporary file when creating 8-bit optimized palettes uses a temporary
file whenever you create an optimized palette for Indexed-Color video. This option
speeds up the creation process significantly and should be selected whenever you
plan on creating Indexed-Color video files.
5. Display Options dialog box opens the Options dialog box for any video filter,
transition effect, audio filter, or moving path dropped directly into the Timeline from
the Production Library.
6. Display data rate warning message halts the creation process of any video file
once it exceeds the specified data rate. Leave this cleared if the data rate is not
important or you are creating video files unattended and do not want the creation
process to be stopped.
7. Display New dialog box opens the New dialog box whenever the New button or
File: New command is clicked. If left cleared, any new video project is automati-
cally created based on the attributes of the current Project. If you often create
video projects using the same attributes then leave this option clear.
8. Automatically save every automatically saves the video project at the time
interval specified.
9. Default background color sets the default background color for any color clips.
10. Title safe area margin specifies the margin percentage for displaying any titles
in a video project. This is useful if you intend on sending your video back out to
video tape or for broadcasting, as television has a different resolution than a
computer monitor, and edges which are viewable on screen may disappear. As a
guideline, for NTSC devices choose 12%, for PAL 10%.
11. Default inserted clip duration specifies the duration for any clips loaded into
the Timeline (such as title clips) which do not have a predefined duration. As a
guideline, set this to the number of frames for each second, such as 29.97 or 25
(NTSC, PAL respectively).
