Embodiments of the present invention provide a video encoding system in which a video coding engine establishes coding quality metrics that govern its own operation as well as the operation of a camera and/or a pre-processor. An imaging system may include an image acquisition system, a pre-processor and a coding engine. The coding engine may output a quality indicator identifying, for each portion of a video sequence currently being coded, a relatively level of coding quality that is being achieved. The imaging system further may include an image acquisition controller and a pre-processor controller that impose respective operating parameters upon the image acquisition system and the pre-processor in response to these quality indicators. In this manner, overall performance of the imaging system may be improved.
