The "Position", "Scale" and "Rotation" parameters that are available for some effects can be adjusted directly from Clip or Sequence Viewer. Selecting an effect from the list in the Effect Editor control panel, or double-clicking on the effect area in the viewer window, activates effect editing mode:



You can adjust the height and width of the effect application area by hovering the effect_parameter_resize_on_screen_horiz, effect_parameter_resize_on_screen_vert, or effect_parameter_resize_on_screen_diag cursor over the edges of the image and dragging the resize tool vertically, horizontally, or diagonally:



You can change the position of the effect application area on a particular frame by dragging it with the effect_parameter_relocatecursor:


If animation is enabled for the "Position" parameter, any position change will force a new keyframe to be created at that particular frame, if there was none. In the viewer window you will see the trajectory of all located keyframes and when you start playing a media file, you can track the current position of the effect application area by its center point on the graph:


All keyframes displayed here can be manipulated with the mouse. Drag a keyframe with the effect_keyframe_move_on_screencursor to reposition it in the viewer window. For those keyframes that have handles, dragging the handles with the effect_keyframe_move_handlescursor sets curves to define the keyframe transition pattern.

Refer to the Keyframes Transition section for more information about keyframe manipulation.


It is possible to rotate a clip clockwise or counter-clockwise directly in the viewer using the effect_parameter_rotate cursor:


Typically, a clip is rotating around its anchor point located in the center of the "canvas". You can move this point using the effect_parameter_move_on_screencursor, and then rotate the clip around that point:
