Sony DVS-9000 User Manual page 709

Note
In constant duration mode (see page 707), 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.

Changes in the effect duration caused by deleting a keyframe
• When the effect is stopped on a keyframe, a delete operation deletes the
keyframe, and reduces the effect duration by the duration of the deleted
keyframe.
• When the effect is stopped between two keyframes, a delete operation
deletes the preceding keyframe, and reduces the effect duration by the
duration of the deleted keyframe.
