This will make the button TRANS available in the user interface.
y Select the button TRANS.
A transition appears between the two clips (by default set to a ’Cross-
fade’ wipe):
Figure 6-41: Transition between clips
The exact position of the transition depends on the available head and
tail. If head and tail are sufficiently available for both clips, the transition
will be positioned exactly in the middle of the timeline cursor.
The transition is now added to the timeline and you can proceed, for
instance, by calling up its properties and altering them to adjust the
transition to your needs. How to do this and the individual items avail-
able to change a transition are described in chapter “Timeline Element
Properties” on page 7-1.
To set a transition there must be enough head and/or tail avail-
able of at least one clip to make a blending possible, otherwise
the button TRANS will be unavailable. You can create the nec-
essary head and tail manually by adjusting the in- and outpoint
of clips (see section “Changing In- and Outpoints of Timeline
Elements” on page 6-47).
If you are in the overwrite mode of the timeline, the Edit Tool
will create the head and tail for the transition automatically.
This means that parts of the clips will be moved for the transi-
tion. Due to the moving of the clips the creation of a transition
in the overwrite mode may cause gaps in the timeline. More in-
formation about the overwrite mode can be found in section
“Overwrite Mode” on page 6-35.
You can delete a transition the same way you delete a clip from
the timeline. Simply select its visual representation in the time-
line and press the key [Del] on your keyboard or select from its
context menu the menu option Delete.
Depending on the resolution of the material and the type of
operators used in the timeline, it may be necessary to prerender
the transition (see section “Prerendering of Timeline Elements”
on page 6-46).
