Abstract
Video is used extensively as an instructional aid within educational contexts such as blended (flipped) courses, self-learning with MOOCs and informal learning through online tutorials. One challenge is providing mechanisms for students to manage their video collection and quickly review or search for content. We provided students with a number of video interface features to establish which they would find most useful for video courses. From this, we designed an interface which uses textbook-style highlighting on a video filmstrip and transcript, both presented adjacent to a video player. This interface was qualitatively evaluated to determine if highlighting works well for saving intervals, and what strategies students use when given both direct video highlighting and the textbased transcript interface. Our participants reported that highlighting is a useful addition to instructional video. The familiar interaction of highlighting text was preferred, with the filmstrip used for intervals with more visual stimuli.

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
