In mid-February, OpenAI released a preview of its generative artificial intelligence technology, which can generate up to one minute of realistic videos from text and static images."Sora"In the recent announcement of new features, it was announced that "Sora" will be available in most countries and regions where ChatGPT Plus and ChatGPT Pro services are available.provided for use.
In this release, OpenAI uses an updated model architecture in the new version of "Sora", and the speed of generating videos has also become faster, but it still has its limitations, such as the possibility of abnormal physical phenomena or difficulty in continuously presenting complex movements.
In addition, users can also re-edit the generated videos or mix them into the current clips. The initial generated video specifications will be limited to 1080P and 20 seconds in length. Users who subscribe to the ChatGPT Plus service can generate up to 50 480P resolution videos, or shorter 720P videos. As for users who subscribe to the ChatGPT Pro service, the number of generated videos can be increased by 10 times, or longer and higher-resolution videos.
OpenAI also emphasized that in the future it will tailor functions for different types of users so that it can generate video content that meets specification requirements. It is expected to be launched in 2025.
Each generated video will be preset with a digital watermark and metadata that complies with the C2PA (Coalition for Content Provenance and Authenticity) technical standards. It will also restrict users from creating child sexual abuse and sex-related deepfake content through "Sora". This is done by restricting the upload of photos of real people's faces. At the same time, it also emphasizes that it will continue to improve its protection measures against deepfake content.
OpenAI said that "Sora" will be available in most countries and regions where ChatGPT Plus and ChatGPT Pro services are available, but it will take additional time to be available in the EU and the UK, where privacy information is more sensitive.
