These prompts often involve rarely co-occurring concepts with long-distance semantic relationships, falling outside training distributions. Existing methods typically apply test-time scaling for improving video quality, but their fixed search spaces and static reward designs limit adaptability to imaginative scenarios. To fill this gap, we propose ImagerySearch, a dynamic test-time scaling law strategy inspired by imagery that adaptively adjusts the inference search space and reward guided by prompts, effectively enhancing generation quality in imaginative scenarios. Furthermore, we introduce LDT-Bench, the first benchmark targeting long-distance semantic prompts, designed to evaluate the creativity of video generation models. It comprises 2,839 challenging concept pairs from diverse recognition datasets and incorporates an automatic evaluation protocol to assess creative capacity. Extensive experiments on LDT-Bench demonstrate that our approach consistently outperforms general generation models and test-time scaling approaches. Additionally, ImagerySearch achieves strong performance on VBench, confirming its effectiveness in improving video generation quality under diverse conditions.<\/jats:p>","DOI":"10.1609\/aaai.v40i13.38044","type":"journal-article","created":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T00:01:01Z","timestamp":1773792061000},"page":"10700-10708","source":"Crossref","is-referenced-by-count":0,"title":["ImagerySearch: Adaptive Test-Time Search for Video Generation Beyond Semantic Dependency Constraints"],"prefix":"10.1609","volume":"40","author":[{"given":"Meiqi","family":"Wu","sequence":"first","affiliation":[]},{"given":"Jiashu","family":"Zhu","sequence":"additional","affiliation":[]},{"given":"Xiaokun","family":"Feng","sequence":"additional","affiliation":[]},{"given":"Chubin","family":"Chen","sequence":"additional","affiliation":[]},{"given":"Chen","family":"Zhu","sequence":"additional","affiliation":[]},{"given":"Bingze","family":"Song","sequence":"additional","affiliation":[]},{"given":"Fangyuan","family":"Mao","sequence":"additional","affiliation":[]},{"given":"Jiahong","family":"Wu","sequence":"additional","affiliation":[]},{"given":"Xiangxiang","family":"Chu","sequence":"additional","affiliation":[]},{"given":"Kaiqi","family":"Huang","sequence":"additional","affiliation":[]}],"member":"9382","published-online":{"date-parts":[[2026,3,14]]},"container-title":["Proceedings of the AAAI Conference on Artificial Intelligence"],"original-title":[],"link":[{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/38044\/42006","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/38044\/42006","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T00:01:02Z","timestamp":1773792062000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/view\/38044"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,14]]},"references-count":0,"journal-issue":{"issue":"13","published-online":{"date-parts":[[2026,3,17]]}},"URL":"https:\/\/doi.org\/10.1609\/aaai.v40i13.38044","relation":{},"ISSN":["2374-3468","2159-5399"],"issn-type":[{"value":"2374-3468","type":"electronic"},{"value":"2159-5399","type":"print"}],"subject":[],"published":{"date-parts":[[2026,3,14]]}}}
