[Mp4-tech] Do the motion estimation happens only after the calculation of PMV ?

[hungary]

Hai Experts,
In case motion estimation we come across PMV(Predicted motion vector ).
Which decides the search point form where actual motion estimation algo
starts.
Do the motion estimation happens only after the calculation of PMV ?
or we can do the same independently without doing PMV calculation ?
If so which is the origin point from where we need to start for search?
Regards
