What does this literature support, and not support, for turning any existing video into a playable or directable world?

Synthesis, not a result. Papers support: (a) learning a small discrete or continuous control interface from unlabelled video in a domain (platformers, robot arms, rendered walkthroughs); (b) copying a motion between clips with released AdaWorld/Olaf-World-style models in the authors' tests; (c) adapting such a model to real controls with little labelled data. They do not support, by what was inspected: arbitrary film footage with cuts and moving cameras; long persistent worlds (Genie's 16-frame memory; AdaWorld's limit beyond the initial scene); named, stable player controls; rights clearance of the source video. Treat a latent-action world from existing video as a research-preview capability that must be probed per source, not assumed. Curator qualifications: Synthesis is well bounded. Wording: AdaWorld's stated limit is that it 'struggles to create novel content when the rollout exceeds the initial scene' (content generation), not a long-horizon consistency limit like Genie's 16-frame memory. Reword the AdaWorld item: novel-content limit beyond the initial scene, not memory/consistency. Evidence status: curator/producer inference or synthesis from the cited sources (code read, not executed, where code is cited); correlated desk review (Claude); not independently reviewed.
