Sony MVS-8000 User Manual page 157

The effect duration may also be changed by inserting or deleting keyframes.
Changes in the effect duration caused by inserting a keyframe
• When the effect is stopped on a keyframe, inserting a keyframe increases the
effect duration by the duration of the inserted keyframe.
• When the effect is stopped between two keyframes, inserting a keyframe
does not change the effect duration.
Note
In constant duration mode (see page 155), the duration of the current keyframe
is reduced to zero, and the new keyframe is inserted with the previous duration
of the current keyframe. Thus the effect duration does not change.
