Amazon Enhances Nova Reel AI Video Model with Extended Video Length
Amazon has upgraded its artificial intelligence (AI) video model, Nova Reel, now enabling the creation of videos extending up to two minutes in duration. This update significantly expands the capabilities of the generative video tool, positioning it as a more robust contender in the rapidly evolving field of AI video generation.
Background: Nova Reel Enters Generative Video Market
Introduced in December 2024, Nova Reel marked Amazon’s initial entry into the generative video realm. This AI video generation tool competes with offerings from OpenAI, Google, and other entities in an increasingly competitive landscape.
Nova Reel 1.1: Longer Videos and Consistent Style
Nova Reel 1.1, the updated iteration, is capable of producing “multi-shot” videos maintaining a “consistent style” throughout, according to AWS developer advocate Elizabeth Fuentes. Users can input prompts of up to 4,000 characters to generate videos up to two minutes long, composed of six-second segments. This enhancement allows for more complex and narratively rich video content creation.
Introducing Multishot Manual Mode for Enhanced Control
Nova Reel 1.1 also features a new “Multishot Manual” mode. This mode allows the model to utilize a reference image alongside a text prompt, providing enhanced control over the composition of video shots. Fuentes indicates that by supplying a 1280 x 720 resolution image and a prompt of up to 512 characters, users in Multishot Manual can create videos comprised of as many as 20 shots. This feature offers users greater precision in directing the visual output of the AI video model.
Access and Ethical Considerations
Nova Reel remains exclusively accessible through Amazon Web Services (AWS) platforms, including Bedrock, Amazon’s AI development suite, and requires users to request access. Like many generative AI systems, questions surround the ethical methods employed in Nova Reel’s development.

Copyright and Training Data Transparency
Generative video models are trained using extensive datasets of videos to discern patterns for creating new video content. Concerns exist that some companies train these models on copyrighted videos without proper authorization from copyright holders. This practice raises the risk of intellectual property lawsuits for users if these models reproduce copyrighted material. Amazon has not disclosed the sources of Nova Reel’s training data, and has not offered a clear mechanism for content creators to opt out of having their videos included in training datasets. However, Amazon has stated it will protect AWS customers from copyright infringement claims related to content generated using its models, in accordance with its indemnification policy.
Correction Regarding Access to Nova Reel
Correction: A previous version of this report incorrectly suggested that obtaining access to Nova Reel from Amazon required special dispensation. While access requests are necessary, AWS grants these approvals automatically. We apologize for this inaccuracy.
