Abstract	Although NLE (nonlinear editing) becomes widely used for multimedia contents creation, its deployment for MPEG has not been exploited much due to the inter-frame coding structure of MPEG. We propose two fast algorithms in order to realize dissolve operation of MPEG coded data. One is based on the baseband method (BBM) where dissolving is performed in the pixel domain. The other uses the transformed domain method (TDM). Since motion estimation is altered due to the transition and its re-calculation process greatly increases the computational complexity, we use texture information to determine dominant motion during dissolving and avoid the motion estimation calculation. In the experiment, it is observed that fast dissolve processing using BBM can be achieved at less than half of the conventional BBM with at most 1 dB penalty. As for TDM, although it achieves the same processing speed of that of the proposed BBM, larger degradation is found due to the restricted motion accuracy.
