Abstract
The MPEG-2 bitstream syntax offers a great variety of coding mode options for encoding a macroblock. We present an MPEG-2 compliant interlaced video encoder that employs an efficient macroblock coding mode selection method. The macroblock coding mode is selected based on a rate-distortion criterion. However, a computational analysis as well as predictive and statistical modeling techniques are introduced that lead to substantially better computation-performance trade-offs. The proposed MPEG-2 video encoder is shown experimentally to be better than the MPEG-2 TM5 encoder in both compression performance and computation requirements, simultaneously.

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
