In order to transmit the pre-coded video stream through bandwidth constrained network, downsizing transcoding technique has been introduced because it can reach very low bit rate without losing any motion information. With the proposal of arbitrary downsizing, fine gradual reduction of bit rate and video quality becomes feasible. However, there is little research focusing on frame size selection for arbitrary downsizing transcoding. In this paper, we propose an efficient method to estimate the number of bits allocated to residue information in re-quantization process. By estimating lower bound of bit rate of corresponding frame size, a reliable decision can be made. Experimental results show that, proposed method can provide an accurate estimation.
