Interpretation of the Diagrams and Examples
The upper diagram maps the chronology of the source clip (vertical axis and position bar to the left)
against the chronology of the destination clip (horizontal axis and position bar). In its initial state when
you call a clip that has not yet been edited, the following applies:
Source clip chronology = destination clip chronology.
The straight red line in the display represents this state: The mark-in and mark-out points of the source
and destination clips are identical with regard to timecodes. Each individual frame in the source clip is
mapped on the corresponding destination clip.
In order to understand all the Timewarp functions, it is important to know that “position” in the spatial
sense (as applied to a video tape) has nothing to do with the position bars. These bars deal with time
.
The lower diagram indicates the speed (vertical) throughout the destination clip time axis (horizontal).
In the initial state, the straight red line runs horizontally at a height of 1.0 (100 percent), i.e. in a constant
positive play direction.
Some examples:
Linear Slow Motion at Half the Standard Speed
For linear slow motion at 50%, the destination clip becomes twice as long as the source clip. The speed
remains constant, which is why it is called “linear slow motion”.
Linear slow motion at 50% play speed (factor of 0.5)
A Key Frame is set at the first frame of the source clip that is assigned a speed parameter of 0.5. The
resulting straight blue line ascends less steeply than the standard red line.
