Chapter 7: Video effects 135
The Delete button is available whenever the current
frame has a keyframe; that is, whenever the Current
keyframe indicator shows a number rather than a dash.
The Keyframe time counter shows the time offset
within the clip of the current movie time – the frame
showing in the Player. The first keyframe is therefore at
time zero, and the last is at an offset equal to one frame
less than the duration of the clip.
When the current frame has a keyframe, its time offset
can be changed with the counter’s jog arrows. The
positions of the first and last keyframes cannot be
adjusted. Others can move freely between the current
positions of their neighboring keyframes.
Setting the time of keyframe 3.
Previewing and rendering
While you are working with the Video effects tool,
choosing effects and adjusting parameter settings, the
Player gives a dynamically-updated preview of the
current frame in your movie. Previewing a single frame
may not be very revealing when you are working with
effects that evolve over the duration of the clip (like the
Water drop effect, page 146). In those cases, you will
need to play back the clip to see the full impact of the
effect you are applying.
Because many effects require intensive calculation, a
fully smooth and detailed preview of the full clip won’t
