i assume you mean blocking artefacts, in that case, use postprocessing (most 
effective) or increase the bitrate or limit the maximum quantizer or reduce 
the framerate, thare are also many many other things you should do like using 
rate distorted mb decission, trellis quantization, ...

btw, it would have been helpfull if you would have provided a little bit more 
information like the used command lines
