A proposed class action in a US federal court accuses New York-based Runway AI of harvesting videos from YouTube without permission to train its generative video models, a claim that would add to a mounting wave of litigation over how copyrighted material is used to build artificial intelligence. According to the BBC, the complaint was filed in California and alleges that Runway bypassed YouTube’s copyright protections to obtain user content for training purposes. [2]

The lawsuit, brought by YouTuber David Gardner in Los Angeles, contends Runway’s alleged scraping violated YouTube’s terms of service and California’s unfair competition law and asks a judge to allow a wider group of rights holders to join as plaintiffs. The complaint seeks unspecified monetary damages and frames the action as part of a broader effort by creators to hold AI firms accountable for unconsented use of their work. [2]

Runway is not a small independent: it completed a $315 million financing round that raised its valuation to about $5.3 billion, according to reporting on the deal. Investors named in coverage of the round include General Atlantic, Nvidia and major asset managers, funds Runway says will be used to accelerate development of its generative systems and expand into media and entertainment.

The company’s recent model releases have substantially expanded its capabilities. Reporting describes Gen 4.5 as enabling high-definition video generation from text prompts with native audio, long-form multi-shot outputs and improvements in character consistency and editing tools, features that help explain why large, diverse datasets would be valuable to train such systems.

Creators and artists have increasingly turned to the courts to challenge data practices across the AI industry; the BBC and other outlets note parallel suits from authors, visual artists and other YouTubers targeting major firms such as OpenAI, Nvidia, Snap, Meta and ByteDance. Those cases are testing the legal boundaries of scraping, licensing and fair use as companies race to build more capable models. [2]

The complaint notes search-and-download techniques it attributes to Runway and seeks class certification to represent additional affected rights holders. At the time the complaint was filed, news accounts said there was no immediate public comment from Runway, its backers or other platforms implicated in the broader debate. The outcome of this case could influence how generative video systems are trained and whether platforms or creators secure new protections or remedies. [2][3]
