OpenAI has updated its Sora 2 video generation platform, increasing the maximum clip length for all users. The changes also introduce exclusive capabilities for Pro subscribers, including a new Storyboard option, available only through the sora.com browser composer.

Following the update, all users can now generate video clips up to 15 seconds in length on both the mobile application and the web interface. A key distinction has been made for Pro subscribers, who gain the ability to create clips up to 25 seconds long when using the browser version. According to a statement from the OpenAI X account, these paying users also receive exclusive access to the Storyboard feature within the sora.com composer.

This new structure marks an increase from the previous limits, which were typically around 10 seconds for standard users and roughly 20 seconds for Pro users operating in the browser. The Sora 2 model itself is powered by OpenAI’s ChatGPT technology.

The extended generation time is intended to allow creators to develop more complete scenes from a single prompt. With additional seconds, a video can establish a tone, build a brief plot, and provide a narrative conclusion. This runway offers more space for shots to feel intentional, with sufficient time to stage action and execute narrative turns. It also provides room to layer elements such as pacing cues, deliberate camera movements, and shifts in mood without the final output feeling compressed. For professional users, the ability to pair a 25-second clip capacity with the new storyboard functionality allows for a sequence to be mapped out before committing generation credits.

This update establishes a clearer division between casual and more structured video creation projects. The 15-second limit available to all users is positioned for producing quick drafts, short-form social media snippets, mood pieces, or fast conceptual tests that fit within a single scene. The Pro subscription, when accessed via a browser, is geared toward users who require longer videos, tighter pacing control, and the efficiency of storyboard planning. This planning tool is designed to reduce the number of retries and the amount of time spent on polishing content, which is a benefit for small teams. The updated feature set positions Sora 2 among the leading AI video generators currently available.

Future development may focus on tools that transform these 25-second generations into genuine edits rather than just longer rendered clips. The competitive landscape will also be shaped by how rivals respond, as the field of AI video generation involves advancements in user control as much as in clip duration. Google’s Flow and Veo platforms are reportedly advancing their control features, creating a higher standard for Sora. A video cap beyond 25 seconds could enable fuller explainer videos and cleaner narrative arcs.

The web-based storyboards will require finer controls, such as shot reordering, trimming capabilities, and quick overlays, to allow for timing adjustments without needing a complete reroll. If competitors release versions that surpass the 25-second mark or introduce lightweight editing timelines, Sora will likely need to accelerate the development of its planning features and improve iteration loops within its browser interface.
