In order to achieve AVCs fall potential in intracoding efficiency an encoder must choose an appropriate coding option for each block in every frame. This leads to a significant computational effort. In this paper, we investigate employing the AVC 4times4 integer transform in order to decide intraprediction size and mode for AVC encoding in an efficient manner. The transform is used to constrain the encoding options with a feasible overhead, as it can be implemented using shifts and additions only.
