ReView: a digital video player to support music practice and learning
Bibliographic record
Abstract
Thanks to the emergence of digital video, producing and distributing video is now possible in ways that were previously limited to video production companies. Yet the functions of current digital media players differ little from the VCRs play, rewind, fast-forward, and pause functions, which may not support learning tasks appropriately. Therefore, we designed an enhanced digital media player, ReView, to better support video-based learning. To test ReViews usefulness, advanced music students in the Young Artists Programme of the National ArtsCentre of Canada were given the opportunity to use the media player to review a video recorded lesson. In this paper, we present the students ratings of the usefulness of ReViews features, and the frequency with which the features were used. We discuss these findings with respect to technological support for browsing video content. Additionally, we present findings related to the content of the video that the students chose to watch. Specifically, we found that students prefer to watch themselves play rather than review instructions received from a coach.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
