Abstract
With the ever growing popularity of video services, maintaining high Quality of Experience (QoE) of the end users with heterogeneous devices and network conditions is becoming more challenging. Each user requires content that matches with their device capability and network conditions. This motivates the need for flexible video transcoding, which enables changing the properties of videos on-the-fly to fit different users. However, the transcoding process is compute intensive especially when handling modern video coding standards such as High Efficiency Video Coding (HEVC) and supporting emerging applications such as live broadcasts. Consequently, there is a need for lightweight and resource-efficient systems that can perform transcoding quickly at real-time to sustain desired user QoE requirements. We design and implement a container-based video transcoding system to address this need. We experimentally show that our system can meet real-time transcoding while using less computational resources than a native transcoding approach. Our work also identifies container and transcoder parameters that can impact the overall performance of the proposed system.

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
