A video compression circuit including a video pre-processor, a macroblock data storage unit and a video processor is provided. When fulfilled by an input video signal, the video pre-processor converts the input video signal to generate a macroblock data. The macroblock data storage unit alternatively and temporally stores the macroblock data generated from the video pre-processor. The video processor alternatively reads the macroblock data stored in the macroblock data storage unit, and compresses the readout macroblock data to an output video signal.

A video encoding method and system are provided for encoding a video sequence. The video sequence includes N sub-sequences which each includes a plurality of frames. When the video encoding system encodes the jth frame in the ith sub-sequence of the video sequence, the frames previous to the jth frame in the ith sub-sequence have been encoded. Based on the encoded frames, an initial quantization scale is generated. According to the initial quantization scale, the jth frame of the ith sub-sequence is encoded in the inter-encoded mode. Whether the jth frame in the ith sub-sequence is a 'scene change' relative to the (j&#x2212;1)th frame in the ith subsequence is judged, and if YES, based on the initial quantization scale, an adjusted quantization scale is generated. Moreover, the jth frame in the ith sub-sequence is re-encoded in accordance with the adjusted quantization scale.
