CLIPSTER Edit Tool User Guide
The combo box Preset allows you to select common timing changes
from its drop-down list. Once one of the predetermined settings is se-
lected, the Manual items will be adjusted accordingly.
The Resize Timeline Element check box resizes the clip automatically
in the timeline accordingly once the settings for stretching/compression
are confirmed. When time stretched, the clip will be lengthened in the
timeline (outpoint of the clip moves to the right); when time com-
pressed, the clip will be shortened (outpoint moves to the left). If the
check box is deactivated, the length of the timeline element in the time-
line will be preserved, meaning when time stretched, the outpoint of
the clip will be trimmed back; and when time compressed, the possible
alteration depends on the available tail of this clip (without tail a time
compression will not be possible).
The configured time stretching or time compression will be in effect for
the clip in the timeline as soon as it is confirmed with the OK button.
The button CANCEL closes the window without altering the settings.
Time stretching or time compression can also be performed directly in
the timeline. This may be helpful when adjusting clips to a specific
length in the timeline, for example, to fit inbetween two other clips. For
this the Time stretching mode menu option on the context menu of
a clip has to be activated (check box in front of menu option activated).
Then all alterations to the clip’s in- or outpoint in the timeline (see sec-
tion “Changing In- and Outpoints of Timeline Elements” on
page 6-47) will be a time stretching or time compression and the values
in the time stretching or time compression window will be altered au-
tomatically. With this the clip and its in- and outpoint can be easily
aligned to other elements in the timeline via the snapping mode of the
Edit Tool to ensure it provides the correct length in the timeline (in- and
outpoint remain constant while the speed is changed).
6.4.14 Relinking Clips
Clips of either video or audio can be relinked in the timeline, i.e. they
can be referenced to other source material manually from the timeline
directly. To do this perform the following:
y Select the clip whose source material should be changed in the
timeline.
y Then select from the context menu of this clip the menu option
Relink clip… (see section “The Context Menu of Video Clips” on
Clips can be set back to a speed of one (1) easily by setting the
speed factor back to one (1). However, depending on the time
stretching factor(s) used rounding errors may occur, meaning
for frame accurate length you may have to trim the outpoint of
the clip.
