Timewarp Editor
Setting and Editing Key Frames
The Timewarp Editor contains the usual range of buttons for setting, deleting and copying Key Frames
(for basic information, see “Key Frames” on page 529).
However, it also allows you to do the following:
 Set a Key Frame -
Press the
CTRL key and click the desired position in the grid. The mouse pointer changes to a
hand with an extended index finger and a plus sign. This applies to the upper and lower dia-
grams. The curve changes accordingly.
 Move a Key Frame -
The mouse pointer with the extended finger appears next to the Key Frames and can be used to
move Key Frames to new positions.
Key Frames in the Timewarp Editor are absolute, i.e. when the Timewarp clip is subsequently trimmed,
the distribution of Key Frames over the length of the clip does not
change, instead the currently applica-
ble parameters are extrapolated before the first and after the last Key Frame.
Linearize/Delinearize Segment
Firstly, this function serves to create direct transitions, such as a sudden shift from “forward” (speed of
1.0) to “reverse” (speed of -1.0).
Secondly, linearizing results in a steady progression of motion between two Key Frames, i.e. without
acceleration or delay. For more information, see the example under “Linear and Nonlinear (Curve)” on
page 798.
This function always is always applied to the left-hand
Key Frame and the next Key Frame to the right:
Select a Key Frame (color changes to orange), click the button (click while holding down the
SHIFT key to
delinearize). The Key Frames appear as vertical bars of differing heights, depending on their original
position:
Linearized segment with Key Frames
The results of the function are visible in the upper diagram where the transition between two Key Frames
is linearized or delinearized. Curves become straight lines, and vice versa.
