This contribution presents results of tests applied to several tools in the current WD and HM (3.0) to verify whether the included tool produced the intended effects. Each set of results have been cross-checked. Based on the results, this contribution recommended removal of the following tools as they do not show clear benefits in terms of coding efficiency, complexity and design consistency:

1. 
   Center position of TMVP candidates;
   
2. 
   Chroma codeword switch;
   
3. 
   Direct coding of Intra DC coefficient in CAVLC mode;
   
4. 
   Parallel deblocking filter decision;
