Overview

SLoMO brings together researchers working on the story-level understanding of long-form, edited videos—particularly movies and TV episodes. Building on the success of the first edition at ICCV 2025, this 2nd edition continues our invited talks + competition format with in-person attendance, and broadens the discussion to long-form edited media understanding and how deeper movie comprehension can benefit generative models.

Compared to conventional video tasks, this setting demands: (i) modeling long-range narrative dependencies; (ii) reasoning over complex character relationships; and (iii) understanding editing patterns and cinematography.

  • Invited Talks showcase recent advances in Audio Description (AD), movie understanding, and accessibility for visually impaired audiences.
    We address the following key open questions:
    • How can we ensure fair evaluation of large vision-language models, particularly with respect to knowledge leakage from movie data?
    • How can movie understanding advance accessibility in edited media?
    • How can modeling movie structure and cinematography benefit both story-level understanding and movie generation?
  • SLoMO Competition evaluates narrative-level reasoning through two complementary tracks: Movie Question Answering (MovieQA) over full story arcs, and Audio Description (AD) Generation producing coherent, story-aware narrations to enhance accessibility for visually impaired audiences.

SLoMO Competition

The SLoMO Competition advances story-level video understanding through two complementary tasks: Movie Question Answering (MovieQA) and Audio Description (AD) Generation. The competition is designed to evaluate long-form, narrative-level reasoning in video-language models, going beyond clip-level perception toward coherent story understanding.

Datasets

  • Short-Films 20K (SF20K) — a large-scale, publicly available collection of 20,143 self-contained short films totalling 3,684 h. Each film lasts 5–40 min (~11 min on average) across diverse genres, with both automatically generated and manually curated QA pairs.
  • Condensed Movie Dataset (CMD-AD) — short clips from over 1,432 online movies with professionally annotated Audio Descriptions from AudioVault, temporally aligned with the clips.

Tracks

  • SLoMO QA Track: Movie Question Answering (MovieQA)
    Dataset: SF20K (19,071 train / 50 public test / 45 private test movies).
    Metric: LLM-QA-Evalgpt-4.1-nano compares ground-truth and predicted answers and assigns a binary correctness label; the final score is the percentage of correct answers.
    Example MovieQA question and answer
  • SLoMO AD Track: Audio Description (AD) Generation
    Datasets: CMD-AD (1,332 train / 98 public test / 100 private test movies) + SF20K (zero-shot, 17 public test / 45 private test movies).
    Metric: a single AD score -- a weighted combination of
    ADQA (a question-answering measure of how well the ADs convey the story's visual content, leveraging gemini-3.0-flash)
    CIDEr (n-gram agreement with reference ADs). The exact weights are not disclosed
    An AD Duration Check (conformance to the expected length of audio descriptions) is performed for each AD as a qualifying check, and does not contribute to the overall score.
