Pruning method in different prediction mode

An apparatus for processing video data, comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:

• determining, based on a video characteristic of a first video block, an enabling or disabling of a pruning process for a table updating process;
• updating one or multiple tables, based on the determination and motion information of the first video block, wherein the one or multiple motion tables are History-based Motion Vector Prediction HMVP (HMVP) tables;
• and
• performing a conversion between a subsequent video block of the video and a bitstream of the subsequent video block based on the updated tables.

A non-transitory computer-readable recording medium storing a bitstream of a video which is generated by a method performed by a video processing apparatus, wherein the method comprises:

• determining, based on a video characteristic of a first video block, an enabling or disabling of a pruning process for a table updating process;
• updating one or multiple tables, based on the determination and motion information of the first video block, wherein the one or multiple motion tables are History-based Motion Vector Prediction HMVP (HMVP) tables;
• and
• generating the bitstream of a subsequent video block of the video from the subsequent video block based on the updated tables.
