Hi @charred sapphire. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Sora 2 currently generates videos up to 10 seconds long by design. This limitation is set to ensure the best possible quality, realism, and responsiveness to user direction for short clips. The model is optimized for creating short, high-fidelity videos with synchronized audio, and longer durations may introduce challenges in maintaining visual quality, accurate motion, and instruction-following. If you need longer videos, you may need to generate multiple clips and combine them externally, as Sora 2 does not support generating videos over 10 seconds at this time Getting started with the Sora app.

For reference, Sora 1 on web (with ChatGPT Pro) allows up to 20 seconds, but Sora 2 on the app and web is currently capped at 10 seconds per video Getting started with the Sora app.
