Techniques and tools for deriving chroma motion vectors for macroblocks of interlaced forward-predicted fields are described. For example, a video encoder or decoder determines a prevailing polarity among luma motion vectors for a macroblock. The encoder or decoder then determines a chroma motion vector for the macroblock based at least in part upon one or more of the luma motion vectors having the prevailing polarity.
