  • QSVideo: Human-Style Search that Tames Long Videos

    QSVideo: Human-Style Search that Tames Long Videos
    2026/09/07

    This episode breaks down QSVideo, a human-inspired framework that finds the few critical frames in long videos by rewriting questions, weighting object/action/location importance, and scoring frames with a lightweight semantic ranker.

    QSVideo uses diversity based metric, an anchor-and-expand (or recency-first for streams) traversal, and parallel ranking to deliver notable accuracy gains on LVBench and StreamingBench, run much faster than prior methods, and plug into existing video-language models without retraining.

  • Beyond Language Modeling: An Exploration of Multimodal Pretraining

    Beyond Language Modeling: An Exploration of Multimodal Pretraining
    2026/03/06
    In this episode, we discuss Beyond Language Modeling: An Exploration of Multimodal Pretraining by Shengbang Tong, David Fan, John Nguyen, Ellis Brown, Gaoyue Zhou, Shengyi Qian, Boyang Zheng, Théophane Vallaeys, Junlin Han, Rob Fergus, Naila Murray, Marjan Ghazvininejad, Mike Lewis, Nicolas Ballas, Amir Bar, Michael Rabbat, Jakob Verbeek, Luke Zettlemoyer, Koustuv Sinha, Yann LeCun, Saining Xie. The paper investigates native multimodal foundation models by training from scratch on diverse visual and language data using the Transfusion framework. Key findings include the effectiveness of Representation Autoencoder for unified visual representation, synergy between vision and language data, emergence of world modeling from unified pretraining, and the role of Mixture-of-Experts in efficient multimodal scaling. The study also reveals a scaling asymmetry with vision requiring more data than language, which MoE architectures can balance to enable truly unified multimodal models.

  • Mode Seeking meets Mean Seeking for Fast Long Video Generation

    Mode Seeking meets Mean Seeking for Fast Long Video Generation
    2026/03/04
    In this episode, we discuss Mode Seeking meets Mean Seeking for Fast Long Video Generation by Shengqu Cai, Weili Nie, Chao Liu, Julius Berner, Lvmin Zhang, Nanye Ma, Hansheng Chen, Maneesh Agrawala, Leonidas Guibas, Gordon Wetzstein, Arash Vahdat. The paper presents a novel training paradigm combining mode seeking and mean seeking to decouple local video fidelity from long-term coherence using a Decoupled Diffusion Transformer. It employs a global Flow Matching head trained on limited long videos for narrative structure and a local Distribution Matching head aligned with a frozen short-video teacher to ensure local realism. This approach enables fast synthesis of minute-scale videos that maintain both high-quality local details and coherent long-range motion, significantly improving the fidelity–horizon trade-off.
