TSS uses a uniformly allocated checking pattern and is prone to miss small motions. NTSS <ref name=tss>{{cite journal|last1=Li|first1=Renxiang|last2=Zeng|first2=Bing|last3=Liou|first3=Ming|title=A New Three-Step Search Algorithm for Block Motion Estimation|journal=IEEE Trans. Circuits And Systems For Video Technology|date=August 1994|volume=4|issue=4|pages=438–442}}</ref> is an improvement over TSS as it provides a center biased search scheme and has provisions to stop half wayhalfway to reduce the computational cost. It was one of the first widely accepted fast algorithms and frequently used for implementing earlier standards like [[MPEG]] 1 and H.261.
 
The algorithm runs as follows:
