Method and apparatus for video coding

A method for video decoding, comprising:

• receiving prediction information of a current block, the prediction information indicating that a prediction of the current block is at least partially based on an inter prediction;
• receiving a first flag for an intra-inter prediction mode that uses a combination of an intra prediction and the inter prediction of the current block;
• determining that a usage of a bi-directional optical flow mode (BDOF) on the inter prediction is applied only when all of the following are satisfied:
• (1) a height of the current block is not four and a size of the current block is not four by eight,
• (2) the current block is coded using neither affine mode nor Alternative Temporal Motion Vector Prediction (ATMVP), and
• (3) a first reference picture used for the inter prediction is prior to the current block in display order and a second reference picture used for the inter prediction is after the current block in display order;
• and
• decoding a coded video bitstream based at least on the prediction information indicating the inter prediction and the first flag indicating the intra-inter prediction mode without using the BDOF.
