A method for supporting video coding includes obtaining an image frame including a plurality of coding block groups each including one or more coding blocks, using a first coding control model associated with a first coding block group in the image frame to estimate one or more first coding parameters, using a second coding control model associated with a second coding block group in the image frame to estimate one or more second coding parameters, determining one or more effective coding parameters based on an evaluation of the one or more first coding parameters and the one or more second coding parameters, and using the one or more effective coding parameters to encode the plurality of coding block groups in the image frame.
