When your video creative is ready and you're confident it follows the technical specs and the content requirements listed in the Advertising Guidelines, click "Add creative" at the bottom of your Campaign page.
This will open an "Add creatives" side bar where you drag-and-drop a file or find it on your device by clicking "browse".
After it passes technical review, your creative will be manually reviewed for 2-3 business days. If there's a technical or content issue, it'll be in review for another 2-3 business days.

The creatives that are being reviewed or that have been approved will appear in your creative library and you can assign those to campaigns.
