1. A method of encoding video content, the method comprising: assigning a predefined quantization model to each of at least two regions of interest of video content, wherein a respective region of interest of the at least two regions of interest comprises a rectangular-based region covering less than a full frame identified on a frame-by-frame basis by a first descriptor associated with top left corner coordinates of a first sub-segment in the respective region of interest and a second descriptor associated with a last sub-segment in the region of interest, wherein the first descriptor and the last descriptor define a defined structure of the respective region of interest based on a number of sub-segments in the respective region of interest, wherein the respective region of interest includes an arbitrarily shaped object in a portion of the respective region of interest that is smaller than the defined structure of the respective region of interest; and encoding at an encoder of a plurality of encoders each of the at least two regions of interest based on the predefined quantization model assigned to the defined structure of the respective region of interest, the encoder using quantization model information to encode each of the at least two regions of interest differently based on the assigned predefined quantization model.
