Earlier versions of the tool were limited to shorter clips and lower image quality. The latest update aims to improve visual smoothness and clarity, making the videos more usable for storytelling, creative projects and social media.

According to Mint report, the update also adds more advanced audio features, including expressive character voices and background music that can be matched to video content. These additions are intended to create a more cohesive viewing experience.

The new model has also improved its ability to understand prompts. The system is designed to better follow detailed instructions and allow users to refine scenes through follow-up inputs without starting over.
