Amazon Nova Reel

Amazon Nova Reel is a proprietary multimodal foundation model (FM) designed for enterprise use cases. Amazon Nova Reel generates a novel video from a descriptive natural language text string and an optional reference image (together, the “prompt”). Customers can use Amazon Nova Reel to create content within advertising, branding, product design, and social media workflows. This AI Service Card applies to the use of Amazon Nova Reel via Amazon Bedrock Console and Amazon Bedrock API. Typically, customers use the Console to develop and test applications, and the API for production loads at scale. Each Nova model is a managed subservice of Amazon Bedrock; customers can focus on executing prompts without having to provision or manage any infrastructure such as instance types, network topology, and endpoints. An Amazon Nova Reel <text prompt, <optional image prompts>, generated video> triple is said to be "effective" if a skilled human evaluator decides that the generated video: 1/ has the content requested by the input prompts (the combination of text and optional image prompts); 2/ makes reasonable assumptions about elements not specified in the input prompts (for example, if asked for a video of a kitchen, a refrigerator and microwave are present and not a couch or a tiger); 3/ is free from defects or image composition errors (for example, human body parts are attached in the correct places and objects are not warped); and 4/ is consistent with the standards of safety, fairness, and other properties valued by the evaluator. Otherwise, a triple is said to be "ineffective." A customer's workflow must decide if a generated video is effective using human judgment, whether human judgement is applied on a case-by-case basis (as happens when the Console is used as a productivity tool by itself) or is applied via the customer's choice of an acceptable score on an automated test
