Li would like to create a video asset for his recent campaign. He wants to augment his brand's existing video assets and feature brand elements like ratings and product details. Which of the following tools can he use?

The correct answer is Streaming TV studio because this tool allows advertisers like Li to create and enhance video assets by integrating brand elements such as ratings and product details effectively. The Streaming TV studio is specifically designed for producing engaging video content tailored for streaming platforms, making it ideal for augmenting existing video assets. In contrast, Amazon Ads production and editing services may involve more comprehensive production efforts but may not specifically focus on the quick integration of brand elements, while Amazon Video Builder is typically used for creating ads from scratch rather than augmenting existing assets, making Streaming TV studio the most suitable choice for Li's needs.
