Instead of training one large end-to-end model, the team combined existing lightweight components, including a MobileViCLIP-based video encoder, an MDETR-derived spatial encoder-decoder, and a shared text encoder. Timing is handled by either a small 1D U-Net or a basic thresholding step, letting the same setup work in both weakly supervised and zero-shot modes. The whole pipeline runs on fewer than 90 million parameters, and video features can be precomputed before any query ever arrives.\n\nMost spatio-temporal video grounding systems lean on heavyweight multimodal large language models or complex training pipelines, which makes them costly to run at scale. Pocket-STVG matches weakly supervised baselines and beats earlier zero-shot approaches while using a fraction of the memory and compute those methods need. That efficiency matters more than incremental accuracy gains for anyone trying to search large video archives rather than demo a single clip.\n\nIt is a reminder that in video AI, bigger model and better model are not the same claim. Sometimes recombining smaller, proven parts wins on the metric that actually ships: cost per query.","[\"video-ai\",\"computer-vision\",\"efficient-ai\",\"video-grounding\"]","2026-09-28T04:00:00.000Z","2026-09-28T07:18:58.845Z","2026-09-28T07:19:05.381Z","published",null,[],"ai",[26,27,28,29],"video-ai","computer-vision","efficient-ai","video-grounding",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.31135",0,{"sections":36},[37,40,44,49,54,59,63,68,73,78,83,88,92,97],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",4689,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",758,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",399,"2026-09-27T18:39:02.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",261,"2026-09-27T15:30:35.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",188,"2026-09-27T20:46:36.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":18},"Science","science",148,{"name":64,"slug":65,"count":66,"latest_published_at":67},"Consumer Tech","consumer-tech",135,"2026-09-26T14:30:00.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":72},"Software","software",91,"2026-09-25T20:55:00.000Z",{"name":74,"slug":75,"count":76,"latest_published_at":77},"Dev Tools","dev-tools",84,"2026-09-26T04:20:58.000Z",{"name":79,"slug":80,"count":81,"latest_published_at":82},"Startups","startups",76,"2026-09-25T18:33:59.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"Gaming","gaming",48,"2026-09-25T18:35:21.000Z",{"name":89,"slug":90,"count":86,"latest_published_at":91},"General","general","2026-09-26T17:02:42.000Z",{"name":93,"slug":94,"count":95,"latest_published_at":96},"Reviews","reviews",30,"2026-09-24T20:07:31.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
