Abstract: A method of video processing includes determining, for a conversion between a current block of a video and a bitstream representation of the video, an operation associated with a list of motion candidates based on a condition related to a characteristic of the current block. The list of motion candidates is constructed for a coding technique or based on information from previously processed blocks of the video. The method also includes performing the conversion based on the determining.

Abstract: A mechanism for processing video data implemented by a video coding apparatus is disclosed. The mechanism determines to apply template-based intra mode derivation (TIMD) to a block based on whether the block is dyadic or non-dyadic, where TMID is associated with intra prediction. A conversion between a visual media data and a bitstream is performed by applying intra prediction to the block based on TIMD.

Abstract: A mechanism for processing video data implemented by a video coding apparatus is disclosed. The mechanism determines to split a coding tree unit (CTU) into one or more coding units (CUs). One or more of the CUs may be one or more prediction tree units (PTUs). The mechanism further determines to recursively split the CUs into prediction units (PUs). The method performs a conversion between a visual media data and a bitstream based on the PUs.

Abstract: A mechanism for processing video data implemented by a video coding apparatus is disclosed. The mechanism determines to apply a prediction splitting tree to a prediction tree unit (PTU). The prediction splitting tree includes a leaf prediction unit (PU). A prediction mode is selected for the leaf PU based on whether the leaf PU is split from the PTU. The method performs a conversion between a visual media data and a bitstream based on the leaf PU.

Abstract: Video processing methods, systems and appratrus are described. One example method includes performing a conversion between a video block of a video and a bitstream of the video using a palette mode in which samples of the video block are represented using a palette of representive color values. A size of the palette of the video block is determined based on whether a local dual tree is applied for the conversion.

Abstract: A method implemented by a video coding apparatus. The method includes determining that a scalability dimension information (SDI) supplemental enhancement information (SEI) message precedes a multiview acquisition information (MAI) SEI message in decoding order whenever an access unit (AU) contains both the SDI SEI message and the MAI SEI message; and performing a conversion between a video and a bitstream of the video based on the SDI SEI message and the MAI SEI message. A corresponding video coding apparatus and non-transitory computer readable medium are also disclosed.
