To run it in your campaign, contact our support team at [support@novastudio.ai](mailto:support@novastudio.ai)  --- ### **What Is the Collection Format?** Encourage people to move from discovery to action in an immersive way by pairing your hero asset with an interactive gallery. **Best used for:** - Drive product discovery - pair your hero asset with relevant imagery in a scrollable grid so shoppers see more of what you sell in one ad - Interactive browsing experience - audiences can hover to pause the scroller, then browse the products at their own pace - Turn discovery into action - move shoppers who interacted with the ad through to your website or landing page 📌 The layout of this format may change. Contact our support team for the latest version.  --- ### **Creative Specifications** Have your assets ready before you contact our team. | **Asset** | **Specifications** | | --- | --- | | **Main Media** | • Aspect Ratio: 1:1, 4:5, 16:9 or 9:16 • Video: 1080p, .mp4 or .mov • Image: Min 350×350 px, .jpg or .png • Max File Size: 3MB • Can be imported from a social post | | **Image Carousel** | • 3+ images, no limit • 4+ images appear as a scrolling carousel • Aspect Ratio: 1:1 • Min 150×150 px, 72dpi • File Type: .jpg or .png • Max File Size: 3MB • Each image can link to its own destination URL • Can be imported from a carousel post or product listing | | **Advertiser Name** | • Max 25 characters • Appears at the top of the creative, before the caption | | **Destination URL** | • All clicks on the CTA, caption and images go here | | **Ad Placements** | • Flex, 300×600 and 320×480 | 💡 We recommend using Nova Studio flex-sized ads to get the best rendering.
