Abstract
Advances in battery technology have not kept pace with other recent advances in mobile multimedia systems with the result that power consumption is a major concern. The computational complexity of video codecs, which consists of CPU operations and memory accesses, is one of the main factors affecting power consumption. In this paper, we propose a method that achieves good video quality while at the same time guaranteeing that the complexity needed to decode the video does not exceed a specific threshold defined by a user. We focus on the motion compensation process, including motion vector prediction and interpolation, which is the biggest single component in computation-based power consumption. We formulate the rate-distortion optimization problem and present an efficient method for decoder complexity-aware video encoding in the H.264 video codec. Our results show that our method can achieve up to 95% of the optimal solution value.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
