When you are using the Clone or Reveal tool, you can adjust the controls under the Clone tab to transform the input that's being cloned or revealed. Adjust:
• translate - to move the source image on x and y axis.
• rotate - to spin the source image around a pivot point.
• scale - to resize the source image by adding or removing pixels. Use center (or Ctrl/Cmd+drag the transform jack) to position the pivot point.
• skew X - to skew the source image along the X axis from the pivot point. Use center (or Ctrl/Cmd+drag the transform jack) to position the pivot point.
• skew Y - to skew the source image along the Y axis from the pivot point. Use center (or Ctrl/Cmd+drag the transform jack) to position the pivot point.
• skew order - to set the order in which skew X and skew Y are applied:
• XY - Skew X is applied before skew Y.
• YX - Skew Y is applied before skew X.
• round to pixel - check this to round the translate amount to the nearest whole integer pixel. This can help you avoid softening when using filtering. If source is set to color on the Stroke tab, this control is disabled.
• filter - to select the appropriate filtering algorithm. For more information, see Choosing a Filtering Algorithm.
• black outside - When rotating or translating the clone source, a part of the image area may get cropped. To fill the cropped portion with black, check black outside. To fill the cropped portion by expanding the edges of the image, uncheck black outside.
• time offset - to clone or reveal pixels from a different frame. Time offset is either relative to the current frame (-1 is the frame previous to the current one) or absolute (1 is the first frame in the clip).
• view - to select which view you want to clone from in a stereoscopic project.
