Amazon Bedrock Workshop - ValidationException in Nova Reel workshop

[arun-gupta]

This is regarding Amazon Nova Reel workshop and using the Jupyter notebook to modify the prompt.

I change the prompt to create a reel and got the following error:

ValidationException: An error occurred (ValidationException) when calling the StartAsyncInvoke operation: Malformed input request: #[/textToVideoParams/text](https://bedrock-workshop-a3lk.notebook.us-east-1.sagemaker.aws/textToVideoParams/text): expected maxLength: 512, actual: 676, reformat your input and try again.

Is that a Nova Reel limitation or workshop? If its Nova Reel, then 512 is not sufficient to express a prompt for generating video.

Just for fun, here was the prompt:

create a video for Amazon Bedrock Workshop, title: `Build with GenAI – Join the Amazon Bedrock Workshop`, keep the tone professional, use Instagram reel format
scene 1: 0-2s, visual: Clean animation of a developer coding in a modern IDE with "Amazon Bedrock" text on screen. voiceover/Text: Build with Generative AI, no model training needed.
scene 2: 2-5s, Visual: Quick flash of supported models: Anthropic, Cohere, Meta, Stability AI, Amazon Titan  voice over/text: Access top foundation models with a single API.
#scene 3: 5-6s, invite developers to take the workshop, with a clear CTA to a link to https://catalog.us-east-1.prod.workshops.aws/workshops/a4bdb007-5600-4368-81c5-ff5b4154f518/en-US
