An apparatus comprising:

• means for receiving digital video content;
• means for receiving an indication of an object of an image of said digital video content;
• means for receiving an indication of a grouping of said object in a frame sequence, wherein said grouping of said object is one of lines or pixels or a combination of lines and pixels, and wherein said grouping of said object defines a horizontal and vertical position of said object within said image;
• means for intra-frame swapping said grouping of said object with a grouping of a neighboring object, wherein said neighboring object is a grouping of an object that follows said grouping of objects in time, and wherein said intra-frame swapping occurs in a forward direction with respect to time;
• means for performing an object assignment for said forward time swap;
• means for intra-frame swapping said grousing of said object with a grouping of a neighboring object, wherein said neighboring object is a grouping of an object that precedes said grouping of object in time, and wherein said intra-frame swapping occurs a backward direction with respect to time;
• and
• means for performing an object assignment for said backward time swap, wherein said forward time swap of objects occurs for half of a pre-determined time interval and said backward time swap occurs for half of said pre-determined time interval.
