A method for allocating bitrate in video communications is disclosed. The method includes encoding, via an encoder, a video stream that is partitioned into tiles associated with a viewing angle of the video stream, whereby encoding the video stream includes allocating each of the tiles a bitrate. The method also includes determining an image quality score associated with rendering of the tiles at a first iteration, whereby rendering of the tiles includes decoding and displaying the tiles at the first iteration in the viewing angle of the video stream with the bitrate. The method further includes, responsive to determining the image quality score, modifying the bitrate allocated to at least some of the tiles such that rendering of the tiles at a second iteration that is after the first iteration includes decoding and displaying the tiles with the modified bitrate.
