How to (reduce the pixel count size) resize of the I frames P frames and B frames by a certain factor ?

If I frames are jpeg compressed and the blocksthemselves would be reduced to half resolution and the I frames to half resolution that would already be effective but how please ?

Also the other types of frames P and B containing motion vectors and plain difference between frames those would also need to be halved in resolution and there would be no necesity of recomputing the motion vectors because motion vectors are very robust to resolution
