Abstract
Pre-trained video-language models (VLMs) have shown superior performance in high-level video understanding tasks, analyzing multi-modal information, aligning with Deep Video Understanding Challenge (DVUC) requirements.In this paper, we explore pre-trained VLMs' potential in multimodal question answering for long-form videos. We propose a solution called Dual Branches Video Modeling (DBVM), which combines knowledge graph (KG) and VLMs, leveraging their strengths and addressing shortcomings.The KG branch recognizes and localizes entities, fuses multimodal features at different levels, and constructs KGs with entities as nodes and relationships as edges.The VLM branch applies a selection strategy to adapt input movies into acceptable length and a cross-matching strategy to post-process results providing accurate scene descriptions.Experiments conducted on the DVUC dataset validate the effectiveness of our DBVM.

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
