a.
When a scene is in Compose Window, its default length is shown in
'total' frame field (on the right) of the frame display window.
If the scene is a "moving" picture clip (e.g. QuickTime,
AVI or SWF movie) the 'total' frames will be default to whatever
that movie length is. If it's a "still" picture clip (e.g.
JPEG, GIF or PNG) the 'total' frames will be default to 12 frames
long (one second). Note that both the 'current' frame number and
the 'total' frame number are user selectable and definable. Meaning:
a typed-in number in either field (with 'Enter' key) will change
the frame position or the length of a scene respectively.
b.
From the default 'total', you can either shorten or prolong the
scene by selecting the 'total' number and replacing it with a new
number (smaller or greater than the original) then pressing "Enter"
key. Now a length definition menu will pop up at the right
of frame display window showing 4 selectable buttons: To
End, To Front, To Cycle and Reset.
To
End: means adding/subtracting frames to/from the end
of the scene. The added footage is the replications (repeats)
of the last frame of the clip. The truncated footage is to be
taken out from the last frame of the clip counting backward.
To
Front: means adding/subtracting frames to/from the
beginning of the scene. The added footage is the replications
of the first frame of the clip. The truncated footage is to be
taken out from the first frame of the clip counting forward.
To
Cycle: means adding/subtracting frames to/from the
end of the scene in a cycling manner. For example, if the original
clip is a 24 frames cycle animation and the new total is 36 frames,
the new scene will contain 1.5 cycle of the original animation.
Vice versa if the new total is 18 frames the new scene will be
0.75 time of the original length (meaning: 0.25 is missing from
completing the original cycle). When "To Cycle" command
is applied to prolong a normal "one way" scene, the
new scene will simply repeat itself at the end of the original
clip.
Reset:
This command will reset the total frame to its original length.
Please note that "original" means the original length
of a movie clip, not the last "defined" or "recorded"
length of a scene.
Note:
The shortest length you can define for a scene is 2 frames (1/6
of a second). But there is no limit on the other end. From 2 frames
to infinity, any number in between is OK.
c. Once a menu command is selected, the length definition
menu will go off and the respective change takes place immediately,
leaving a clickable symbol of your selected "definition"
on the right of the frame display window. (If you clicks
the space outside of the menu, the menu will go off and no length
change will take place.) Now the Record
button will turn red reminding you that a change has been made to
the scene and that you should click "Record" to preserved
this change.
d.
You can continuously make length changes to a scene by reentering
new numbers in the 'total' frame field (with "Enter" key).
Each change is based on the last "modified" parameter.
For instance, you add 6 still frames to the end of a 24-frame animation
cycle, and then you use "To Cycle" command to make the
total frames to 60. This means the new scene contain 2 broken animation
cycles of 30 frames each. If you click the space outside of the
definition menu, the menu will go off without new selection
and the symbol remains unchanged as it was before the menu opened.
e.
After length change(s), you can reset a scene to its original length
by using Reset command through its definition symbol. To
do so, click on the "definition" symbol of a modified
scene to bring up a menu with a sole Reset button in it (all other
buttons are dimmed out and unselectable in this menu). For making
additional length changes you should follow the same steps described
in paragraph b) and c).
Note:
You can't bring back the normal length definition menu by
clicking a scene's "definition" symbol. The symbol is
mainly to indicate the nature of the last length change to a scene.
And the button itself is solely for the purpose of "resetting"
your scene to its original length.
f.
Only when the 'Record' button is pressed the length change will
be registered to your Timeline.
