Creating Timewarps in the Player

You can create a timewarp in a source clip using the Player by adjusting the speed of the source clip or the duration of the timewarp. You cannot adjust the speed of the source clip independently from the duration of the timewarp.

The timewarp is created when you edit the clip from the Source Area to the Record Area. When an edit is performed using a source clip with a speed change, the source clip is first timewarped according to the speed specified, then the edit is performed.

If you mark an in and out point on the source clip and in the Record Area, and then edit the clip to the timeline, a fit-to-fill edit occurs and the source clip is timewarped so that it fits into the specified region. You can also fit-to-fill a one-frame clip (without marking the source) into a marked region in the Record Area. The edit results in a freeze-frame.

To create a timewarp in the Player:

1. View the source clip in the Player.

   
   

   (a) Speed field  (b) In and Out Point fields    

2. Set the in and out points for the timewarp.
   NoteThe in point and out point frames of the source clip are not guaranteed to be exactly the same after an explicit timewarp. The amount of slippage is proportional to the change in the source after the speed change is applied.
3. Define the timewarp value:
   • To change the speed of the source clip, enter a value in the Speed field.
   • To change the duration of the timewarp, enter a value in the Duration field.
   NoteThe result of editing the values in the Player depends on the constrain setting for each field. For example, if you constrain the Duration field, changing the value in the Speed field does not change the duration of the timewarp. See Constraining Source Clip Timewarp Values.
4. To change the direction of the source clip, click the +/- button. The speed value is preceded by a negative sign (-) when the effect is in reverse.
5. Exit the Player.

   A percentage speed value appears in the lower-right corner of the source clip indicating that a timewarp has been applied.

6. Edit the source clip to the Record Area.

   The timewarp is created.
