Amazon says its AI video model can now generate minutes-long clips

[ad_1]

Amazon has upgraded its AI video model, Nova Reel, with the ability to generate videos up to two minutes in length.

Nova Reel, announced in December 2024, was Amazonโ€™s first foray into the generative video space. It competes with models from OpenAI, Google, and others in whatโ€™s fast becoming a crowded market.

The latest Nova Reel, Nova Reel 1.1, can generate โ€œmulti-shotโ€ videos with โ€œconsistent styleโ€ across shots, explained AWS developer advocate Elizabeth Fuentes in a blog post. Users can provide a prompt up to 4,000 characters long to generate up to a two-minute video composed of six-second shots.

Nova Reel 1.1 also introduces a new mode called โ€œMultishot Manual.โ€ In this mode, the model can reference an image along with a prompt to offer more control over a video shotโ€™s composition. According to Fuentes, given a 1280 x 720-resolution image and 512-maximum-character prompt, Multishot Manual can generate videos containing up to 20 shots.

Nova Reel is only available through AWS platforms and services, including Bedrock, Amazonโ€™s AI dev suite, and customers must request access. As with most generative AI systems, there are questions as to whether Reel was developed using ethically sound methods.

Video-generating models are trained on a vast number of examples of videos to โ€œlearnโ€ the patterns in these videos to generate new clips. Some companies train models on copyrighted videos without obtaining permission from the owners or creators, and, when these models โ€œregurgitateโ€ copyrighted stills, it exposes users of the models to IP lawsuits.

Amazon hasnโ€™t revealed the source of Reelโ€™s training data, nor has it provided an explicit way for creators possibly feeding the modelsโ€™ datasets with their videos to opt out. The company has, however, said that itโ€™ll protect any AWS customers accused of violating copyright with media generated by its models, in keeping with its indemnification policy.

Updated 4:57 p.m. Pacific: An earlier version of this article implied that developers have to request special access from Amazon to use Nova Reel. Thatโ€™s incorrect; while developers have to request access, AWS automatically approves these requests. We regret the error.
